There is no shortage of articles written on the Los Angeles River, and I’ve covered some of the broader hidden hydrology work being done there in a previous post here, Beyond the LA River. I do however have a special affinity for the quality of scholarship on Places Journal, and an essay from May 2018, Willful Waters by USC’s Vittoria Di Palma and Alexander Robinson doesn’t disappoint.  This longform essay provides a great background and historical framework for anyone wanting to understand the river and it’s long and contentious history, as well as recent efforts of revitalization and reconnection.   It also comes with a great collection of historical imagery, which elevates our thinking out the past, present, and future river beyond the concrete ditch we tend to associate with the Los Angeles River.

I’d recommend the essay in its entirety, so I’ll just include a few snippets and comments I thought were compelling.  At first I was a bit confused about their allusion to the Thomas Cole series The Course of Empire in this context, but after some explanation, it’s an interesting framework in which to think about hidden hydrology, in terms of binaries such as life/death or sin/redemption, and as a “cyclical” journey from wildness through some sort of apex and back through destruction and desolation.  That narrative begins another cycle of  “revitalization” and “restoration”.  As the authors mention: ” If not for the galvanizing effect of a set of historical ideas — the belief that a site, destroyed and degraded by human industry, could be transformed into something evocative of its original condition through the power of “nature” guided by enlightened design — Los Angeles might have continued to forget that it ever was a river city.”

From a historical viewpoint, the idea of a soft, meandering river is hard to comprehend, but also is the origin of the city itself, supporting described as “…a stream trickling through a wide sandy bed.”  with “The river basin was overspread with springs, marshes, and shallow ponds (the very name of La Cienega Boulevard recalls the landscape’s original swampy character), and the debris from the mountains, deposited over centuries, created a layer of alluvial silt that in some areas lies 20,000 feet thick.”  This lack of structure meant lots of variability, which created unpredictable volatility during storms and “rain events” in which “…waters would rush down from the mountains, carrying gravel, silt, boulders, and trees.”  This factor would ultimately lead to the demise of the river itself.

The other interesting idea was the concept of zanjas (irrigation ditches), in which there were miles built as shown in the above map:  Quoting John Shertzer Hitell, “The “zanjas, or irrigating ditches, run through the town in every direction.” They “vary in size, but most of them have a body of water three feet wide, and a foot deep, running at a speed of five miles an hour. They carry the water from the river to the gardens, and are absolutely necessary to secure the growth of the fences, vines, and many of the fruit trees.”   The image below showing how these canals were parts of the fabric of the city, enclosed but still open and visible, and enlivened the place, as mentioned in a reference to visitor Emma Adams, who commented on “…the soft murmuring of water as it glides through the zangas [sic] in some of the beautiful suburbs of the city is sweet music to the ear, a happy voice sending out joy and gladness. Wherever it is heard are sure to be seen verdure, flowers, and fruit.” In this way, the wild and unpredictable Los Angeles River was remade into a tractable urban water source.”

The manipulation of the river for utilitarian purposes followed many others before it, but foreshadowed larger interventions of control.  As the authors point out, “Los Angeles was shaped by a dual need to be at a safe distance from its unpredictable, flood-prone river, and in close contact with the river’s highly controlled, artificial reincarnation: the zanja madre and its network of ditches. This relationship between city, river, and ditch is illustrated by the map drawn up by Ord and the surveyor William Rich Hutton in 1849.  Agricultural lands occupy the area between the river and the city up on the Elysian Hills, with the southerly extension of both fields and city closely conforming to the route of the zanja madre. At the same time, the problematic nature of the flood-prone river is indicated by this inscription: “sand over which the River spreads its waters which are wasted.”  They go on to conclude that,“The zanja madre was, in other words, the Los Angeles River tamed and perfected by the improving force of human culture.”

The river at the time was still natural in most places, but the canals soon depleted water levels, and created a trickle, which was the impetus for Mulhollad’s hyperbolic yet apt “Titanic Project to Give [the] City a River”.  After this change to more consistent supply, which included piped water from the Owens Valley some 233 miles away via aqueduct, the Los Angeles River only emerged during rain events, those “… “intermittent moments when it flowed with a violence that only intensified as galloping urbanization further hardened the city’s watershed. No longer valued as a natural resource, the ever-wilder river was now feared as a “predator,” able to roam and strike wherever it wished.”  This unpredictability and ensuing series of floods changed how people thought, thinking of the river as a “menace” and thus “perceptions of the river were changed irrevocably.”

The flooding was the final impetus to use new technology to “train” the “unruly dog” of a river, which seemed to be the particular bailiwick of the Army Corps of Engineers, and creating what amounted to a “water freeway” that we know today. In a few short years, the Corps …systematically transformed the Los Angeles River from an intermittent, meandering stream bordered by willows and cottonwoods into the concrete storm drain we see today.”  The authors point of the lesson of this today.

“In a textbook example of the triumph of reason and human agency over willful nature, the Corps created the ultimate Los Angeles fantasy of a river: a “water freeway.” That a drought-prone region would celebrate the speed at which water could be drained off to the ocean was an irony not then appreciated by either the military engineers or the public.”

Perceptions changed in the 1970s, and the media, politicians, artists, and environmentalists rediscovered the river in a variety of ways.  A series of articles in the Los Angelse Times by Dick Roraback in 1985 entitled , ” “Up a Lazy River, Seeking the Source: Your Explorer Follows in the Footsteps of Gaspar de Portola.” provided a poignant story about the forgotten waterway, where “… the  author narrated his expedition from the river’s mouth to its putative source, chronicling the riparian habitats of its flora and fauna. Roraback’s picaresque tale turned the Los Angeles River into an incongruous backdrop for a cast of quirky urban characters (the blonde waitress, the salty sea dog, the mussel gatherer, the dog-walking divorcée) engaged in various activities, both licit and illicit, in the river and along its banks. By presenting the river as a neglected urban feature, the series brought its paradoxical charms to the attention of a large new audience, and, crucially, positioned the river as a postindustrial terra incognita — an attractive, slightly dangerous, and alluring urban landscape.”  

Further work by artists and others who started exploring the waterway, and ultimately went on to found the Friends of the Los Angeles River, started to think about the area in different ways, and through exploration,  began as a “…characterization of the river as a paradise lost, a place of discarded things and marginalized people, served to ignite a potent landscape imaginary. It also introduced the idea of the river as a space for environmental action. ”  This was aided by the Donald C. Tillman Water Reclamation Plant which added 20 million gallons of water per day, which had an effect of revitalizing the ecology of the river.  “This infusion of wastewater generated a verdant riverscape, which in turn, and somewhat improbably, inspired comparisons with the earlier paradise described by Father Crespí and sparked talk of a riparian rebirth. As the changing river increasingly evoked that lost, idealized waterway (particularly in the unpaved eleven-mile stretch known as the Glendale Narrows), it also inspired residents to take up walking, bike riding, bird watching, horseback riding, and even kayaking and canoeing…”

The kayaking wasn’t always for pleasure, as it was interesting to learn that a waterway has to be navigable to be eligible for the Clean Water Act, so a group of people in 2008 kayaked the length of the river to provide its navigability.  This meant that maybe “The fantasy of transforming the flood control channel into an arcadian waterway began to seem real. Kayaking has also become a powerful means of introducing visiting dignitaries to a vision of a newly green and civic river.”  The final part focuses on the long and winding road of Revitalization, including master plans in through the 1990s and more recently efforts by interdisciplinary design teams, government agencies, and non-profits.  These focused on ecology, hydrology, and recreation, amongst other factors, either as technical studies but more often than not art intervetions or designs.  One such example is the Piggyback Yard Feasibility Study (image below), done by Mia Lehrer + Associates, which “…integrates economic and hydraulic modeling with community design considerations, but such efforts such are still few in number and small in scale.”

The mix of design, art, tours, and other creative methods of interpretation, often using minimal intervention, hint at “…the remarkable activity generated by the Los Angeles River — which as yet remains largely a concrete channel bisected by a thin course of water — testifies to the profound power of the city’s desire for ecological redemption and urban rebirth, and to ways in which civic or even poetic acts have found purchase within a byzantine network of managerial interests.”

The post in Places referenced above is an excerpt from what sounds like a great book, River Cities, City Rivers published by Harvard University Press and edited by Thaisa Way.  Will track down and report on at some point on this book, but here’s a summary from the site:  “Cities have been built alongside rivers throughout history. These rivers can shape a city’s success or cause its destruction. At the same time, city-building reshapes rivers and their landscapes. Cities have harnessed, modified, and engineered rivers, altering ecologies and creating new landscapes in the process of urbanization. Rivers are also shaped by the development of cities as urban landscapes, just as the cities are shaped by their relationship to the river.  ¶  In the river city, the city river is a dynamic contributor to the urban landscape with its flow of urban economies, geographies, and cultures. Yet we have rarely given these urban landscapes their due. Building on emerging interest in the resilience of cities, this book and the original symposium consider river cities and city rivers to explore how histories have shaped the present and how they might inform our visions of the future.”

Our understanding on the arc of history around hidden hydrology is informed with maps and accounts from early explorers and settlers to areas, augmented with records, diaries, and oral histories. Often this neglects and misses the valuable stories of indigenous inhabitants of areas, and leaves us with a significantly shorter timelines for reference. The role of archaeology is vital to unlocking the layers of hidden hydrology that don’t emerge from these illustrative written histories, so I was really intrigued with a recent tweet from the Museum of London Archaology (MOLA) (Twitter: @MOLArchaology) that told of their current work, called London’s lost river: the Tyburn.  From their site, the project is the result of “…a team of expert geoarchaeologists  whose work is helping us to understand London’s lost rivers. As an educational charity, we want to share what we’ve learnt, so please join us to explore the story of this long-lost river.”   

Using the interactive ESRI Story Map, MOLA developed a narrative to describe the process and some of the key findings.  Much of the work is conducted along with construction sites, which gives an opportunity to look below the surface while excavation is happening.  The River Tyburn flowed on the north bank of the Thames, and most famously, was routed and defined the space called Thorney that Westminster Abbey was located, seen in this view circa 1530.

The origins of the river are tied to the longer history of the Thames, which is illustrated (see header image) and reaches back to the last glacial period of 11,500 years ago.  From there in, “…this new epoch, known as the Holocene, the Thames began to take the shape we know today, but many channels still criss-crossed the river’s floodplain within the wide gravelly valley. One of  these channels was the Tyburn, which flowed into the Thames.”   In this zone, there are hundreds of sites, or ‘deposit logs’ that are recorded, and these are modelled to create a snapshot, particularly focusing on the depths of land (depicted below as green – high ground and purple – low ground.  From this model, “projected possible courses for the River Tyburn, following the lowest-lying areas of the modelled 11,500-year-old topography.” with a caveat that “the river would have migrated over time.”

Drilling down (literally) into the specificity of the deposits shows the ranges of material and how it can inform, looking at “ancient flora and fauna” and focusing on things like Diatoms, Pollen, and fossils of things like “Ostracods, the remains of small crustaceans, can indicate salinity, water depth, temperature, water acidity/alkalinity”.

Below is “…a cross section, or transect, running north–south from Westminster to Vauxhall Bridge, along the north bank of the Thames. This connects deposit sequences recorded in trenches and boreholes, and helps us look at these sequences over wide areas.”

They also connect their study with the work of Barton and Myers 2016 book ‘The Lost Rivers of London‘ (see here for a post on the same), which speculated on a number of scenarios for the Tyburn, and various routes.  There’s some graphic things I’d change here (namely it’s hard to read the Barton and Myers layers) but the concept is interesting, to overlay varying studies and ‘proof’ the concepts of routing. In essence, does the data reflect the speculation on routes, either reinforcing or disputing what was speculated?  The below map is a composite of this

There’s links to some coverage in London Archaeologist, such as a 2014 article in which “… Tatton-Brown and Donovan used historic documents and maps to suggest that the medieval waterways separating Thorney Island from Westminster were man-made and that the Vauxhall Bridge route was the original and only course of the river.”  The 3D views of the route and the illustration of the provide a speculative view of the area.  From the site:  “Our topographic model supports Barton and Myers’s suggestion that discussing two distinct branches (towards Westminster and towards Vauxhall Bridge) is an over-simplification of what was probably a more complex delta-like network, as shown [below] (artist Faith Vardy).  This geoarchaeological study provides a baseline for reconstructing the evolving landscape; when combined with historical records and archaeology, even more detailed models could be created. The research done by others, such as Tatton-Brown, which focuses on later periods, may be supported by geoarchaeological work undertaken in the future.”

The concept of geoarchaeology is pretty fascinating as well, and worthy of some further exploration.  In the interim, you can check out the MOLA site for what their team does, which focuses on using “…auger or borehole surveys and interpret the archaeological soils and sediments retrieved, allowing us to reconstruct past landscapes and environments.”  The reason for this particular subset is to pick up “…where the archaeology is too deeply buried for traditional excavation techniques to succeed. It is also a cost-effective archaeological evaluation tool and geoarchaeological deposit modelling, which maps buried landscapes and deposits.”  This is relevant as the surface remnants of these, but the underground deposits, so they work in a “…wide range of depositional environments, including alluvial floodplains, fluvial environments and estuarine/intertidal zones. Using palaeo-environmental proxy indicators, such as pollen and diatoms, we reconstruct past environments. Our specialists also use a range of sedimentological techniques.”

These techniques don’t answer every questions, but coupled with expertise and interdisciplinary research, enables us to see further, and deeper than previousl.  The role of archaeology and geoarchaeology in hidden hydrology is vital, as shown above. While we often rely on maps, photos, sketches, and written histories to reconstruct places,

A few months back, I posted part one of this dual post on sensory ways of interpreting spaces and art with a focus on the amazing work around Smellscapes. Part two, as advertised, will shift gears a bit, to think about Soundscapes, and how audio can be used to illuminate places, tell stories, and engage the senses in new ways.  And there’s a lot of exciting stuff happening in this space, and this will barely scratch the surface of what people are doing, but I am focused mostly on that which is relevant to the agenda of hidden hydrology, or in ways that are not directly relevant, could inspire some new methods of intervention and interpretation.

The idea of sound is expressed in a number of interesting ways, and more importance is placed on soundscapes in design, or the larger urban sphere, and the impacts of things like noise and how it impacts humans and other species.  Or conversely, it may just be confronting the dilemma posed by White Noise, in their article about innovative sound artists “The Trouble With Sound Is That It’s Invisible.”  New ways of thinking about these topics more holistically show up under terms like Acoustic Ecology, or Sonic Ecology, which thinks about it from a broader way of thinking.  From the abstract of a introductory paper on Soundscape Ecology , the idea for the authors is that:

“The study of sound in landscapes is based on an understanding of how sound, from various sources—biological, geophysical and anthropogenic—can be used to understand coupled natural-human dynamics across different spatial and temporal scales.”

A great resource on the topic I’ve found is The Acoustic City, which is a book/CD and website focused “on sound and the city…  The book comprises five thematic sections: urban soundscapes with an emphasis on the distinctiveness of the urban acoustic realm; acoustic flânerie and the recording of sonic environments; sound cultures arising from specific associations between music, place, and sound; acoustic ecologies including relationships between architecture, sound, and urban design; and the politics of noise extending to different instances of anxiety or conflict over sound. This innovative essay collection will be of interest to a wide range of disciplines including architecture, cultural studies, geography, musicology, and urban sociology.”  

INTERACTIVE SOUNDSCAPES/WALKS

There’s a number of leaders in the field, but I will lead off with one of the rock-stars of this sub-genre that is doing inspired work around water is Leah Barclay, who seems to be everywhere doing amazing work.  From her bio: “Leah Barclay is an Australian sound artist, composer and researcher working at the intersection of art, science and technology. She specialises in acoustic ecology, environmental field recording and emerging fields of biology exploring environmental patterns and changes through sound. Over the last decade her work has focused on the conservation of rivers, reefs and rainforests through interdisciplinary creative projects that inspire communities to listen.”   One such installation is called Hydrology, which is a collection of sounds “…recorded using hydrophones (underwater microphones) in freshwater and marine ecosystems across the planet.” and River Listening, which is “an interdisciplinary collaboration designed to explore the creative possibilities of aquatic bioacoustics and the potential for new approaches in the conservation of global river systems.”   Her work is also available at this interesting site 100 Ways to Listen, from Queensland Conservatorium Griffith University, which has a ton of great soundscape info, focusing on “exploring the art and science of sound and documenting a decade of innovative music-making.”

The idea of interactive sound around water has a few specific precedents worth focusing on hidden hydrology directly.  A project I mentioned a few years back is relevant, SCAPE’s work in Lexington, Kentucky. which featured that of a series of listening stations and a self-guided ‘Water Walk‘ for their project around Town Branch Commons, to tell the story giving users:  a broad understanding of the biophysical area around the Town Branch, reveals the invisible waters that run beneath the city, and demonstrates some of the impacts each resident of Lexington can have on the river and its water quality. By sharing how water systems and people are interrelated—both locally and globally—the Town Branch Water Walk makes stormwater quality relevant, linking it with the history, culture, and ecology of the city.”

Another project that really embodies the potential of this is a School of the Art Institute of Chicago (SAIC) project from professor Linda Keane and artist Eric Leonardson called  RiverWorks, which is described as “…an interactive transient sound mapping and community engagement series of classes that reimagines and visualizes the sustainable world above and beneath the surface of the Chicago River. Challenging engagement with water, water habitats, water conservation and water quality, students activate new connections and thinking about the Chicago River as a healthy, working and recreational ecology. Inspired by John Cages’ 1978 Dip in the Lake series of acoustical experiences throughout Chicago, the course captures sounds of water, water use and misuse in the city.” 

Students explore and create art, around walking, sensing, and as a project called River Listening, which is exciting as an “interdisciplinary collaboration examines creative possibilities for marine bioacoustics and the potential for new approaches to the conservation of urban global river systems…  students fabricate hydrophones for listening for wildlife diversity below the river’s surface. Connecting invisible riverine life with urban water infrastructure, River Listening activates familiar places with unfamiliar information creating immersive spaces. Students experience interactive listening labs and document field recordings in preparation for sound maps, spontaneous performances, and installations that creatively use everyday technologies.”

An article in Open Rivers Journal from 2017 by Christopher Caskey provides a fascinating context for this work.  “Listening to a River: How Sound Emerges in River Histories” which posits that environmental historians could use sound more to develop inquiry into environments.  Drawing from Peter Coates article “The Strange Stillness of the Past: Toward an Environmental History of Sound and Noise”, in which Coates “argues both for “knowing nature through sound” and “picking up nature’s voices” in his case for analyzing sound in environmental history”, the article focuses this idea on rivers, ending with this important conclusion:

“Rivers are particularly auditory places. They make their own sounds and they have played important roles in influencing aural culture. Whether as a storytelling device, as part of an analysis, or even as an inclusion for the sake of posterity, the sounds of a river, both past and present, are worth documenting as part of the historical record.”

SOUND MAPS

An interesting strategy is to provide maps of sounds, which tie the auditory with the spatial, as mentioned in this abstract “growing research initiatives that take up soundmapping as a way of inquiring into pressing spatial, geo-political and cultural issues primarily in cities and also in the endangered wilds.”  This happens in a few ways, but can include modern soundscapes, where there are no shortage of maps and sites documenting the sounds of places, including global maps, such as this one from Cities and Memory, or Locus Sonus and to cities as diverse as Charlottesville, Virginia, Florence, ItalyShanghai, China, and  Montreal, Canada (below)

Each map comes with its own agenda, which ranges from nature sounds, biodiversityurbanization, transit, social spaces, art or even places of quiet.  The key, is that these maps have to have some agenda or viewpoint and have some innovative delivery method, otherwise, they will be boring, as pointed out in this great opinion piece on the subject, “Sound Maps in the 21st Century: Where Do We Go From Here?

The idea of mapping historical sounds does have a viewpoint, as it allows ways of connecting to the past, and appreciating the changing nature of urban environments.  One of my favorites is The Roaring Twenties, which gives an extensive spatial overview of NY City by coupling noise complaints and newsreels with places and sounds – giving a hint of a place, more focused on the man-made than natural sounds, but the section ‘Harbor & River’ connects a bit with the hydrology, along with some info on Sewer/Water Construction.

Another extensive example is the London Sound Survey, which is a really ambitious project (more here).  There’s interesting maps of a range of topics both contemporary and historical, including the hydrological, focusing on both exportation of the Thames Estuary, and a  map of London’s waterways “An auditory tribute to Harry Beck’s Underground map, the skeleton which has long lent shape to the city in the minds of Londoners. Here sounds were collected from along London’s canals and lesser rivers.”   

MUSIC

A number of interesting projects focus on music, which can be used to creatively engage with the environment.  Re:Sound is an experimental music series which explores the relationship between forgotten spaces, sound abstraction and the natural environment.

The ClimateMusic Project is another sort of endeavor with a larger mission to “…enable the creation and staging of science-guided music and visual experiences to inspire people to engage actively on the issue of climate change.  As an analogy for climate, music is familiar, accessible, and—for most people—much easier to relate to than articles or lectures. We created The ClimateMusic Project to harness this universal language to tell the urgent story of climate change to broad and diverse audiences in a way that resonates, educates, and motivates.”

The use of apps is an interesting option as well, melding GPS and music to orchestrate unique experiences that change and evolve as one moves through space.  One I’ve always been excited about is by Bluebrain from 2011 and their installation“‘Central Park (Listen to the Light)’ … a site-specific work of music that responds to the listeners location within the stretch of green of the same name in New York City…  work by tracking a users location via the iPhones built-in GPS capabilities. Hundreds of zones within the landscape are tagged and alter the sound based on where the listener is located in proximity to them. Zones overlap and interact in dynamic ways that, while far from random, will yield a unique experience with each listen. The proprietary design that is the engine behind the app stays hidden from view as the melodies, rhythms, instrumentation and pace of the music vary based on the listeners’ chosen path…. The app is the work itself. A musical ‘Chose-Your-Own-Adventure’ that does not progress in a linear fashion but rather allows the listener to explore the terrain and experience music in way that has never been possible before now. “Read more about this in a NY Times article ‘Central Park, The Soundtrack‘ from when it was released as well, and check out a short video here.

Phantom Islands is an interesting work that exists in the peripheral vision of Hidden Hydrology.  Developed by experimental musician Andrew Pekler, which was part of an oddly intriguing show called Fourth Worlds, Imaginary Ethnography in Musical and Sound Experimentation.   From the site: “Phantom Islands are artifacts of the age of maritime discovery and colonial expansion. During centuries of ocean exploration these islands were sighted, charted, described and even explored – but their existence has never been ultimately verified. Poised somewhere between cartographical fact and maritime fiction, they haunted seafarers’ maps for hundreds of years, inspiring legends, fantasies, and counterfactual histories. Phantom Islands – A Sonic Atlas interprets and presents these imaginations in the form of an interactive map which charts the sounds of a number of historical phantom islands.”   

A screenshot of it is below of one of the ‘entries’, but you really have to go experience it, let loose and have fun.

And, closing the loop on the musical side, there’s a fun Billboard article ‘10 Songs About Rivers‘ which, I feel, focused a bit much on the contemporary and missed some classics, but fun to think about. The BBC has plenty of interesting music, such as the session on Playing the Skyline, in which “musicians look at how the land meets the air and imagine it as music.”  And if we’re getting fully into the influence of environmental on music, a series of works by composer Tobias Picker inspired by Old and Lost Rivers, and even a Lost Rivers Opera from the Czech Republic, which i had a link to in the past but is now no longer working (anyone help there?)

So much more to explore, but this at least provides a primer on sound, and I’m excited to see more about how people are using this media to explore and expand our awareness, specifically focused on hydrology.  Any ideas in that realm, please feel free to comment.

A recent article in the Denver Post “Denver accelerates “daylighting” of lost waterways, “undoing history” with decades-long re-engineering effort” discusses some exciting new work on restoring hidden hydrology and “Re-opening of buried waterways” in the area to manage stormwater runoff and create habitat.  The context:

“Old Denver pulsed with H2O, water that snaked through the creeks and irrigation canals crisscrossing Colorado’s high prairie before 150 years of urban development buried most of them or forced them into pipes.”

A similar story to many cities across the globe, “…developers focused on filling in creeks to make way for the construction of railroads, streets, smelters and housing — all laid out across a grid imposed on the natural landscape.”  This can be remedied today “…by reconstructing the urban landscape where possible, they’ll slow down water, filter it through vegetation to remove contaminants, control storm runoff and nourish greenery to help residents endure the climate shift toward droughts and rising temperatures.”

It’s heartening to see this large of a paradigm shift, and engineers, such as Bruce Uhernik, whom quoted saying:

“We’re just trying to take back that space and make waterways more natural and more beautiful. Why would people not want something to be more natural? This is being responsible — not just to what the city and people need, but to the environment’s needs. Birds. Fish. Trees that should be growing along these corridors. All these work in unison. If you break the chain, things fall off course.”

I appreciate some of the language, but the term “undoing history” is a bit strange to me as I always think of projects like this, in any form, as redoing history.  I guess it’s your take on what is history: the original pre-development condition that needs to be restored, or the interventions and filling as the history that needs undoing.  As mentioned, there’s plenty of history as “Historic Denver maps from the late 1800s show multiple irrigation canals and curving dotted lines denoting unnamed waterways, including a creek that flows through the Montclair Basin from Fairmount Cemetery toward north Denver industrial areas where smelting and rendering plants were located along the South Platte.”  

Either way, it’s a cool project, and has some unique components and context, much of which can be found in the Denver Public Works ‘Green Infrastructure Implementation Strategy‘, a document broad interventions for stormwater and habitat.  The prevalence of creeks is seen in the map of Recieving Waters (page 7) shows that while there are a number of urban creeks, they are impacted by residential, commercial, and industrial development throughout the region,

 

A series of maps in the report outlines pollutants of concern like Fecal bacteria and E.coli, Total Suspended Solids (TSS), Nitrogen, Phosphorous.  This map (page 21) shows subbasin level designations of Nitrogen, which is elevated by human activity, and can lead to algae blooms, and issues with aquatic species.

A focus on the urban core includes the Platte to Park Hill (Part of area 20 above (City Park/Park Hill), which integrates a number of systems.  As mentioned in the report:  “Stormwater Systems is taking a
comprehensive green infrastructure approach to better protecting people and property against fooding while improving water quality and enhancing public spaces.  Four projects are part of the Platte to Park Hill… Collectively, the  four coordinated projects will increase neighborhood connectively, add new park and recreation spaces, provide critical food protection, and improve water quality.” (page 54)  The Globeville Landing Outfall project is one of these segments, as part of the strategy, using open channel design, which “…will help clean storm water naturally when possible and will move the water to its ultimate destination, the South Platte River.”  A rendering of the plan:

The 39th Avenue Greenway (also seen in the header) also includes open channels for flood control and storm events.  The opportunity to layer community function with these facilities is key, as they are “…designed using a community-focused approach to provide the following benefits in addition to flood protection… “ which includes new open space, bike/walking trails, and more.  A rendering shows this integration.

An additional article from the Denver Channel provides a bit more perspective in video form on the Montclair Creek Project, including the “gray to green” approach “correcting past mistakes” focusing on the daylighted river weaving through a golf course and some more urban parts of the City, along with a greenway as mentioned above prior to outlet into the South Platte River.  The funds for the project, which were not insubtantial at $300 million, were voter-approved, with “daylighting of old waterways that were forced into pipes and buried during the industrial revolution in favor or streets, railroads and homes.”

There’s a plethora of early maps of Portland, many of which I’ve recently included and cataloged here for reference.  One of those maps I’d never seen before recently, oddly, is this sketch-map made by William Clark (yes, he of Lewis & Clark expedition fame) from April 3, 1806, featuring a sketch of the Multnomah River, “given by several different Tribes of Indians near its entrance into the Columbia.”  The original link comes from this Oregon Encyclopedia article on the Wapato (Wappato) Valley Indians, found whilst researching native settlements in Portland, notably those around the important confluence of the Willamette and Columbia but getting a feel for pre-settlement use of waterways. The map is found in Volume Four of the Original Journals of the Lewis and Clark Expedition, 1804-1806, which constitutes the return trip of the Corps of Discovery from Fort Clatsop on the Oregon Coast back towards the east.  The entry and fold-out map includes a remarkable amount of information including natural and hydrological features, as well as references to many of the tribes as alluded to in the title.

It’s amazing to see the detail of the map and density of information, in what I assume was field drawn, probably in a canoe, fending off bears while simultaneously collecting plant samples.  I jest, but I’m constantly amazed at the ability of early explorers to represent places quickly and with much    For me, at least, it was much easier to conceptualize graphically if you rotate the map so north is facing up, so the subsequent enlargements flip this over.  This enlarged view shows the key features at the confluence, perhaps not drawn to scale, but remarkably accurate, including to the east, both the Washougal River (noted as Teal) and the Sandy River (noted as the Quick Sand). There are also notes on the various encampments on river banks, such as the Nechacolee and Nechacokee around Blue Lake in Portland on the south bank, Shoto up around modern day Vancouver Lake to the north and many more smaller encampments of the local Multnomah and Kathlamet tribes. To the west, around Wappato Island (modern day Sauvie Island) which was home to Multnomah, Clannahqueh, Cathlahcommahtup and others on Sauvie Island on the Columbia River, and around the other side of the island, known as the Multnomah Channel. See this additional post from the Oregon Encyclopedia for Lewis & Clark’s estimate of the Portland Basin Chinookian Village tribal populations here as well for more detail.

The same zone taken from a Google Earth image shows the general location of and features. The fidelity of the geography is a bit off (it’s a sketch map) but it’s all there.

Further south, the geography is a bit more sparse, but does include the upriver span of the Willamette (called here the ‘Multnomah River’) and it’s connection to the Clackamas River (heading east) including encampments of Clackamas along that river, and perhaps mis-estimating a bit how far away Mt. Jefferson actually was (see below)… and ‘The Falls’ which denotes Willamette Falls, which was an important settlements along this important confluence,  and Charcowah, and Cushhooks near the Falls….

The same view of current day area, again with a bit of misalignment of the rivers, which probably comes from the map being adapted from a drawing done by a local tribal elder, but the general features there.

The text supplements the map somewhat, with stories of meeting a group of Shah-ha-la Nation and showing them the Multnomah:

“we readily prevailed on them to give us a sketch of this river which they drew on a Mat with a coal, it appeared that this river which they call Mult-nó-mah discharged itself behind the Island we call the image canoe island, as we had left this island to the south in decending & assending the river we had never seen it.  they informed us that it was a large river and runs a considerable distance to the south between the Mountains.”

Clark takes a party to explore, and encounters huts from various tribes, along with harvesting of wappato and roots via canoes along the rivers, and found the hidden entrance to the Willamette (which he refers to as the Multnomah River, along with the tribes on Wappato Island and noted the depth of the.  He mentions that he “…can plainly see Mt. Jefferson” which may allude to it’s proximity on the one map.  As he continued to explore he mentions being “satisfyed of the size and magnitude of this great river which must water that vast tract of Country between the western range of mountains and those on the sea coast and as far S. as the Waters of Callifonia…” which if not totally true, does allude to the size of the Willamette drainage in at least draining a fair portion of NW Oregon.  He continues by visiting a long house, and learns the constant refrain of deaths from small pox and starvation. He asks for a map of the area and the people from one of the elders.  “I provailed on an old man to draw me a sketch of the Multnomar River and give me the names of the nations resideing on it which he readiliy done, and gave me the names of 4 nations who reside on this river two of them very noumerous. The first is Clark-a-mus nation reside on a small river… the 2.d is the Cush-hooks who reside on the NE side below the falls.”

They note the entrance to the Multnomah river being “142 miles up the Columbia river” from the Pacific, include the sketched map, and then are off, up-river, continuing eastward.

An excerpt of the journal, the specific passage of which is available via this Oregon Encyclopedia post here as well.

A recent story picked up by multiple sources focused on the potential for hidden hydrological systems to provide heat and cut carbon emissions through tapping into underground lost rivers.  The crux of the argument is that heat pumps could extract heat from these now piped subterranean waterways, and this heat could be used for buildings and other uses, offering an alternative power option for London.  The Guardian offered the potential for heat to “cut capital’s emissions”, and the Times and The Londonist echoed this, focusing on Buckingham Palace as a visible example for the potential for heating buildings.   Mother Nature Network and Earth.com a took a slightly different slant, focusing on helping curb carbon emissions, similar to the coverage from the Daily Mail about using heat from underground rivers to “tackle climate change”.

The specifics come from a group called 10:10 Climate Action, and a recent report highlights ‘Heat seeking in London’s lost rivers’, and looking at the variety of now-buried rivers as a source of power:

“But what if we could use them to power our city once again? Through the magic of heat pumps, London’s lost rivers could provide low cost, low carbon heating and cooling to the buildings above. They could help us solve the big challenge of decarbonising heat.  There’s huge potential for London’s lost rivers to provide clean, efficient and reliable heating for the city – tackling climate change and air pollution. And of course the same technology can be used in other underground waterways like sewers in towns and cities across the country.”

 

y for heat pumps to transfer heat from one place (the subterranean pipes) to another, specifically buildings or other areas via refrigerant, where it is compressed to form heat at the top of the loop, and then expanded to cool down and capture more of the heat.  A primer on heat pumps, as well as a video showing how heat pumps work also helps explain the concept, along with this diagram.

This is already happening in some areas, including Borders College in Scotland, tapping into local wastewater, and the State Ministry Building in Stuttgart, Germany, which is tapping into flow from the Nesenbach, a buried river.  A map extracted from the report (image below) shows a number of the potential sites in London, including The Effra, Stamford Brook, The Tyburn, and the Fleet, all of which have potential sites for the use of these technologies.  Specific places include Buckingham Palace (mentioned in a few of the articles above), which would tap the Tyburn, Hammersmith Town Hall which flows above Stamford Brook, and other buildings like schools and site elements like heated swimming pools, which is currently being done in Paris.  [click to enlarge map below]

A video from 10:10 explains this in a bit more detail, showing an example of a London pub sits atop a lost river and uses this heat pump technology and for it’s heating and cooling.

There’s questions on the cost-benefit, and each of these systems would require some infrastructure to be viable, however it’s pretty exciting to consider the potential of these systems to contribute to energy savings and reduction of carbon emissions, giving back some of their benefits to the city, even while still being buried underground.  I’m sure we’ll hear more about this process in cities around the globe, all of which could utilize similar techniques, as we search for expanded tools to battle climate change and rising energy costs.

A simple yet evocative project, Below the Surface is a catalog of objects found when a canal was drained in Amsterdam, creating a longitudinal timeline spanning from modern day to prehistory.  From the site:  “Urban histories can be told in a thousand ways. The archaeological research project of the North/South metro line lends the River Amstel a voice in the historical portrayal of Amsterdam. The Amstel was once the vital artery, the central axis, of the city. Along the banks of the Amstel, at its mouth in the IJ, a small trading port originated about 800 years ago. At Damrak and Rokin in the city centre, archaeologists had a chance to physically access the riverbed, thanks to the excavations for the massive infrastructure project of the North/South metro line between 2003 and 2012.”

The immensity of artifacts found in this hidden hydrology is amazing, and offer a rare chance to look below the surface (as opposed to underwater explorations, which has a range of limitations).  As mentioned:

“Rivers in cities are unlikely archaeological sites. It is not often that a riverbed, let alone one in the middle of a city, is pumped dry and can be systematically examined. The excavations in the Amstel yielded a deluge of finds, some 700,000 in all: a vast array of objects, some broken, some whole, all jumbled together.

The historical context spans a modern timeline going back many centuries, and the evolution of the site were important and provide context for what was found.  For the Rokin site, seen below, the area: “…served as an inland harbour for boats transporting goods and people from the hinterland. Both banks were densely developed with housing, workshops, shops and institutions, among which the Nieuwezijds Chapel (1347). The local urban fabric was constantly changing as major spatial interventions were implemented.”  

The site gives a detailed overview of the project and the archaeological challenges and opportunities, which include two sites, the Rokin and the Amstel. “For purposes of research, there were two intertwining strands: the city and the landscape. These revolved around the origin and history of Amsterdam. Finds from the river, consisting of (the remains of) ceramic, bone or metal man-made objects (artefacts), afford an insight into the material culture of the city. Ultimately, archaeological remains reflect the everyday activities of humans, in this case, of the inhabitants of Amsterdam and its visitors. As such, they are invaluable in the reconstruction of the historical picture of Amsterdam. The value of material remains as sources of urban history lies largely in their connection with the topographical structure of the city. Hence, the vital importance of the link between the deposits and their spatial origin in urban archaeology.”

The concept of streambed archaeology is well documented also, including the process of retrieval is aided somewhat by their submersion, as mentioned: “Another factor that makes streambed sites unique is their tendency to remain intact on account of the inaccessibility of the sunken objects. Once they had fallen in the water it was not easy to get them out. “  There are specific water focused objects, as well as giving clues to what was adjacent to the waterways: “Quite apart from the physical aspect of archaeological material sinking down in water, underwater depositions differ from deposits on land in the diverse origin and generally mixed nature of the finds. They are primarily associated with shipping activities and vary from items that have fallen overboard to complete shipwrecks and parts of ships. Archaeological remains can also be connected with activities ashore. As such, they can often be linked to objects associated with a building or structure, workshop or installation along the bank.”

The visuals of what has been found is provided in a grid, following chronological order, in order to sort from modern to ancient.  The recognizable debris from the modern era, such as credit cards in the 2000s, jewelry and china from the 1650s, pottery from the 1450s, and even fossiles and shells from early prehistory (listed as -119000).  A temporal snapshot of evolution, and an indication that, among their many urban uses, urban water bodies are a repository for our shared archaeological history.

Beyond this, each individual object is cataloged individually, such as this pocket knife.

There’s also a print version, called Stuff, which is available:

The cultural relevance of this detailed exploration hints at an expansive role of waterways in the urban context as containers for memories and, perhaps a time capsule for objects that can trace our lineage over millennia.

Today I picked up a copy of Richard Sennett’s new book ‘Building and Dwelling: Ethics for the City’. (Farrar, Straus and Giroux, April 2018).   From the website: “Building and Dwelling is the definitive statement on cities by the renowned public intellectual Richard Sennett. In this sweeping work, he traces the anguished relation between how cities are built and how people live in them, from ancient Athens to twenty-first-century Shanghai. He shows how Paris, Barcelona, and New York City assumed their modern forms; rethinks the reputations of Jane Jacobs, Lewis Mumford, and others; and takes us on a tour of emblematic contemporary locations, from the backstreets of Medellín, Colombia, to the Google headquarters in Manhattan. Through it all, he laments that the “closed city”—segregated, regimented, and controlled—has spread from the global North to the exploding urban agglomerations of the global South. As an alternative, he argues for the “open city,” where citizens actively hash out their differences and planners experiment with urban forms that make it easier for residents to cope. Rich with arguments that speak directly to our moment—a time when more humans live in urban spaces than ever before—Building and Dwelling draws on Sennett’s deep learning and intimate engagement with city life to form a bold and original vision for the future of cities.”

While the book aims to hit on a much broader range of topics that we typically cover, the first part resonated on the Hidden Hydrology front with some interesting analysis of the work of that prominent figure in the history, that of Joseph Bazalgette.  For a bit of a primer to the unfamiliar, check out this good post about Bazalgette as “Scientist of the Day” and also behold his amazing mustache below.

Sennett discusses this in Chapter 2, which looks at the evolution of cities in the mid-19th Century, which was a turning point for urbanization that was leading to overcrowding, pollution, and disease, many issues of which had been somewhat unprecedented in modern cities.  As he mentions, “Plague had always been a danger in cities — the Black Death wiped out a third of Europe in the late Middle Ages. As early modern cities became bigger and denser — and so more shit-and-urine filled — they became fertile gardens to feed rats and rat-borne disease.” (21)

Sennett mentions that the first actors in combating this trend were not doctors, but engineers.  Working to improve the quality of urban life, he mentions the ideas around paving of streets as a way to encourage cleaner urban areas, as well as the development of the pissoir  a simple yet seemingly necessary advance in urban sanitation.   The effect of these improvements were functional, but as Sennett points out, the ripple into more livable cities was a unique cross benefit.  As quoted:

“… a knock-on effect of removing shit and urine from the street was that it made the outdoors more usable as social space; the huge outdoor cafe fronting a boulevard was the sanitary engineer’s gift urban civilization.” (23)

The idea that engineering was the major driver for public health in the 19th century, and that it had the residual impact of creating better cities, was often “accidential and unintentional” as Sennett mentions, but often it did come with a direct purpose.  This action-oriented and experimental approach was best embodied by Joseph Bazalgette, and his engineers, working incrementally and often experimentally, invented technologies through trial-and-error:

“The engineers working for Joseph Bazalgette, for instance, when building London’s sewers in the 1850s to 1860s, invented such technology as solid-waste screens in the course of fitting sections of piping together, experimenting with several different filter designs, rather than knowing right away which size to use.  Bazalgette was what to do overall: the realm of the sewer — the realm of Les Miserables — had to be made into a network of pipes mirroring the streets above.”  (24)

The concept of experimentation was an interesting point, as he “often built sewers with pipes larger in diameter than seemed to be needed, saying that planning could not predict future needs,” (24) and as Sennett contends, “One of the truly admirable aspects of Bazalgette’s character is that he exuded Victorian confidence without claiming that he knew exactly what he was doing, believing only that he would get it right in the end.  This is more largely true of civil engineers in the city at the time; their technical knowledge was open-ended.” (25)

The simplified version of the Bazalgette plan shows the series of cross connected interceptors that are all funnelling pollution away from the Thames.

The other element brought up, which deserves more thinking is the “…experimental process required the engineer-urbanist to develop new visual tools,” and that “the messy compound forms along a dense, disordered street requires a different means of representation” (24).

Classical techniques such as plan and section worked to build the infrastructure, as seen above, however they failed to work to communicate concepts as “the infrastructures the engineers were building below ground were invisible” (25).

An image I did find that hints at these new techniques, via the Linda Hall Library, shows the use of cutaway section-perspective to outline the multiple layers of surface and subsurface systems working in tandem.

While I don’t purely think that Bazalgette was motivated by anything beyond doing the right thing, I think the idea of ‘what was the right thing?’ is perhaps the bigger question.  The fact that this ‘modernization’ is often times purely reflected as only a positive move, rubs me the wrong way, as it discounts all the other impacts.  Maybe there was a lack of understanding or lack of imagination at the time, and that burying urban rivers, creeks and streams was the only means available to solve the issues of pestilence, smells, and disease.

The implications, in London, but also world-wide, as these approaches were copies and applied often elsewhere around the globe, had such massive ecological consequences on the hydrology of cities that is, without hyperbole, impossible to reverse. A river or creek sacrificed into a pipe is not the same as a more holistic plan understood and valued the myriad benefits of urban streams and saved these waterways while protecting public health. Sennett’s take that the engineers, as mentioned in the photo caption “Joseph Bazalgette, the finest engineering of the modern city…” (Fig. 1) were saviors and their focus on public health saved many lives is indisputable.  But the cult of this benefit misleads about the cost, and it would be great to counterpoint this message with the worldwide implications of what he and many future engineers wrought on the urban ecology everywhere.

 


HEADER:  London Sewer Plan Map from 1882 – via Wikipedia 

I’ve been inspired by the work many others have done to capture the qualities of coverage of waterways at national scale both in the US and the UK, and beyond the mapping, appreciate their investigations into the unique distribution of place names, or toponyms.  The language of the waterways informs more local hidden hydrology endeavors, and understanding regional vernacular variations provides a snapshot into our varied relationships with water.  While a glance at the Pacific Northwest via these other maps shows that the predominant name for waterways is probably going to be either creek or river, I wanted to dive a bit deeper to see what other names are used to denote waterways.  To accomplish this, I spent some quality time with the USGS National Hydrography Dataset (NHD) to unlock a bit of the secrets of regional variations.

For starters, the NHD is an amazing resource of information, pulling together a comprehensive collection of data on flowlines, watershed basins, and more and the ability to get data from a variety of formats for small to large basins and states.  From their site, the purpose of the data is to: “define the spatial locations of surface waters. The NHD contains features such as lakes, ponds, streams, rivers, canals, dams, and stream gages, in a relational database model system (RDBMS). These data are designed to be used in general mapping and in the analysis of surface water systems.”  The first steps are a bit daunting, as the State of Washington included data with over 1.3 million flowlines, seen below in aggregate. The flowlines aren’t any one single waterway, but are the individual segments that make up each creek.

While the data preserves local basins shapes by sprawling outside state lines, I wanted to make this unique to Washington, so needed to clip it to the state boundary.  This ended up being a bit of a task for my rather slow computer to crank out the clipping, so I had to think of some alternatives to simplify the dataset.  Interestingly enough, over 80 percent of the flowlines (around 1.1 million of them) are unnamed, and while I’m sure are perfectly lovely bits of creek and river, they don’t help in our purpose in terms of deriving place names.  Eliminating them also serves the dual benefit of reducing the size of our working dataset quite a bit.  After trimming to the state boundaries, we ended up with a nice workable set of around 170,000 flowlines that have names, seen below.

Per the NHD FAQ page, “Many features also are labeled with the geographic name of the feature, such as the Ohio River. The feature names must be approved by the Board of Geographic Names (BGN) in order to qualify for inclusion in the NHD.”  More on the BGN and the wonderful assortment of place names that exist in these lists beyond their descriptor (which is perhaps the fuller idea of toponyms), in this case we break down the list and see what comes to the top.   Not surprising, but the use of the terms Creek and River dominate the landscape of Washington, accounting for 98% of all named flowlines.

Of the totals, creeks truly dominate, with around a 75% chance that a trickle of water in the state will be referred to as a creek.  The larger, less numerous rivers make up 23% of all flowlines, and the map above paints a wonderful portrait of the density of waters.  Separated out by type, you see the branched structures of trunk and stem that pumps water through most of the mountainous west side of the state, with the larger, drier plains to the east more open.  All total the combined length of these equals over 30,000 linear miles.

1. CREEKS

2. RIVERS

So we live in a creek and river area of the world.  Amidst these dominating toponyms are a distributed layer of types of flowlines that make up the remainder of the story of Washington, that final 2 percent, emphasized in a darker blue below.

The secondary naming of these includes the most common, isolated and color coded, with a legend denoting the eight most common alternative flowline names.

The relative percentage as a portion of that slim 2% of state flowlines, include:

  1. Slough (30%)
  2. Fork (16%)
  3. Canal (16%)
  4. Ditch (9%)
  5. Wasteway (4%)
  6. Branch (4%)
  7. Run (4%)
  8. Stream (3%)

The remaining 14% are composed of small portions that include Lateral, Brook, Drain, Slu (a variation of Slough), Gulch, Channel, Siphon and it’s alternative spelling Syphon, Washout, Waterway, Swale, Glade, Pass, Gate, and Range.  Many of these as we see, are geographically located towards the center of the state where agricultural landscape has created larger modifications and creation of waterways (described in the NHD data under the names like Artificial Path, Canal Ditch, and Connector).  There’s a split between more traditional waterway name variations (i.e. Slough, Fork, Branch, Run, Stream) and those that mostly utilitarian, capturing the poetry of industrialization (i.e. Wasteway, Ditch, Canal, Siphon, Lateral).  Removing the background landform, you see the composite of the different stream types as a whole, with creek/river in blue and the remainder by color.

For a more local view, the NHD data is a bit less sparse, not capturing the same amount of complexity is smaller urban waterways, plus without the other water bodies like lakes the geography seems somewhat off.  The purple to the west in the Olympic Pennisula shows a density of flowlines referred to as streams, and the darker red denotes a number of local sloughs that exist in local river systems.  It’s harder to see, but you can catch the Ship Canal in this group, and the slightly lighter red fork in the center is the infamous Duwamish Waterway, the lower stretch that runs through Seattle and ‘lost’ its designation as a river – interestingly enough it’s the only flowline in the state with that moniker.

I was expecting the dominance of creeks and rivers in the nomenclature, but was also really surprised that these combined to make up so many of the collective flowlines. Perhaps early settlers and place-namers lacking a bit of creativity.  It was also a good surprise to find a wealth of other place names in Washington, albeit many used to describe man-made features, including the most poetic name of wasteway, but enough fun to find an occasional branch, fork, brook, and run, which are more common elsewhere in the United States, per the other US maps.

These are pretty basic graphics exported from GIS just to give a feel for the data, so I’d like to play around more with representation, perhaps some sort of heatmap.  Also I’m eyeing Oregon for a comparison, and maybe wanting to dive into the waterbodies as well beyond linear flowlines, so more fun to come.  Who knows, an atlas of the whole country with a top ten of their most common names of each state.  Or maybe not…

The exploration of hidden hydrology takes many forms. While often focusing on the visual through maps and illustrations, and the verbal, through documents and texts, there’s a range of other sensory experiences that connect lost rivers and buried creeks to our modern life.

It is vital to connect the lost experiences with actual places, if only help imagine what was there previously, as well as to, surprisingly, find the traces and fragments of the palimpsest that remains after decades or even centuries of erasure. Beyond the idea of just being mere ground-truthing as a method of connecting the maps and texts to actual places, is the ability to engage other senses of touch, hearing, and  We engage and use our brains differently when we’re outdoors versus indoors, as a recent study showed that “…brain activity associated with sensing and perceiving information was different when outdoors, which may indicate that the brain is compensating for environmental distractions.” 

At the root of this is physically experiencing spaces through exploration and discovery. While we will dive into the more specific literature and potential for walking/flâneury in this context of exploration that encompasses our collective sensory experience, for now we will focus on some relevant overlapping themes in terms of specific focused sensing in a spatial frame – specifically soundscapes and smellscapes.  Some, but not all of these fit exactly in the tighter sphere of hidden hydrology, however all do provide valid paths of inquiry that could be directly applied to increasing our understanding and engagement with these buried, disappeared, worlds.

As with all of these explorations, this quickly expanded beyond one post, so I’m focusing first on the concept of smell – and will follow up subsequently with elaboration on other sensory subjects.

Smellscapes

The sounds and smells of water are powerful sensory experiences, which can evoke a range of emotions, hint of hidden landscapes, confront and astound then sooth and delight.  There’s also a strong historical element, outlined beautifully in this CityLab article ‘Sense and the City‘, which discusses Carolyn Purnell’s book ‘The Sensational Past: How the Enlightenment Changed the Way We Use Our Senses’.  in which she shows through explorations of noise, smell, and more over the span of history, “….while our bodies may not change dramatically, the way we think about the senses and put them to use has been rather different over the ages.” 

It is no accident that the events around what led to the massive reconfiguration of London through the burial of rivers into pipes is known as the ‘Great Stink‘, driven by growing water pollution and hot weather which  causing a mass exodus due to the notion that the smells could transmit disease, which was coupled with recent cholera outbreaks.  As mentioned in the Wikipedia article “The problem had been mounting for some years, with an ageing and inadequate sewer system that emptied directly into the Thames. The miasma from the effluent was thought to transmit contagious diseases, and three outbreaks of cholera prior to the Great Stink were blamed on the ongoing problems with the river.”  The scientist Michael Faraday, who investigated and wrote a letter on the poor conditions of the Thames, is depicted in this Punch Cartoon from 1855 holding his nose and “…giving his card to Father Thames”, commenting on Faraday gauging the river’s “degree of opacity”

And while access to land and reduction of negative impact so the irony of much urban modernization of rivers by burying them was often driven by smells, fear of pollution via miasma, or legitimate issues with outbreaks like cholera, the so called “Monster Soup” via the 1828 image by William Health depicting the water of the Thames.

Expanding that notion, I recall this map, via CityLab, of the ‘Stench Map” from the “Charles F. Chandler Papers,” Columbia University Rare Books and Manuscript Library, which was described as a “Map Showing Location of Odor Producing Industries of New York and Brooklyn, circa 1870”

They quote Virginia Tech historian Melanie Kiechle and author of the recent book “Smell Detectives“, who is quoted in the article about the fascination and challenge of spatially representing sensory data: “Trying to show smells, which are not concrete—they’re invisible, they’re ephemeral, they’re always changing…”.  She also authored this paper in Journal of Urban History called ‘Navigating by Nose: Fresh Air, Stench Nuisance, and the Urban Environment, 1840–1880” [paywalled] where she mentions “City dwellers used their understanding of stench nuisance as detrimental to health to construct smellscapes or olfactory maps of New York City. Such maps identified health threats and guided movements through or out of the city.” 

And another, referenced in this Instagram from the NY Public Library Map Division, entitled “Going the whole hog. The odiferous Midtown West in 1865”, which shows this excerpt from a map “Region of Bone Boiling and Swill-Milk Nuisances” found in “Report of the Council of hygiene and public health of the Citizens’ Association of New York upon the sanitary condition of the city” published by The Citizens’ Association of New York. Council of Hygiene and Public Health in 1865″

The short of it was, in the mid 19th Century, cities were often foul and disgusting places, and, if you want a more thorough and frightening description of the above, visit CityLab’s post “The Sanitary Nightmare of Hell’s Kitchen in 1860s New York”  which describes conditions that inevitably existed throughout many cities at the time.  For rivers, this meant modernization, none as famous as the sewerization of London by Joseph Bazalgette, which tackled the issues of urban pollution and flooding in the mid to late 1800s, while also opening up room for development.

This approach served as a model for many areas around the world confronting similar issues, and serves as perhaps the greatest driver of buried creeks and hidden hydrology in modern cities.  Not solely based on smell, but it was definitely a factor.  In entombing these rivers, we cut off the bad but also vacated the positive associations of the smell of water that couple nostalgia via memory. Good and bad, the evocation of smells of water – ocean funk, tidal salt/fresh water mixing, freshness of a bubbling creek, wet grass, and all things in between have strong impacts on our experiences.  One of these concepts mentioned recently in writings I recall, including both a chapter in Cynthia Barnett’s book “Rain: A Natural and Cultural History“, and featured as Robert Macfarlane’s word of the day, is the concept of “petrichor,” which is much more complex but can be simplified as the smell air before, or after rain, which is so evocative as to support an entire industry, outlined in detail in an Atlantic article by Barnett “Making Perfume from the Rain“.

The role smell plays in our experience and enjoyment of places is often not discussed specifically, beyond nuisances, so it is heartening to see artists, designers, and planners taking on this specific area for study.  We will expand more on the water-specific aspects of this in the future, but for now, a great intro is this wonderful meditation on ‘The Conservation of Smellscapes” from the blog Thinking like a Human, which captures the idea better than I, and which also references a couple of the smellscape pioneers which we will discuss in more length below.

Kate McLean

Anyone interesting in the topic of smellscapes has inevitably come across the amazing work of Kate McLean, especially with recent write-ups in Atlas Obscura, The New Yorker, BBC News, and  Co.Design to name a few.  McLean is an artist and designer and current PhD candidate who focuses on sensory research which is found at her site Sensory Maps. and you can follower her as well on her Twitter account @katemclean.  In her websites explanatory text, she mentions the techniques and use of the visual to represent the sensory: “The tools of my trade include: individual group smellwalks, individual smellwalks (the “smellfie”), smell sketching, collaborative smellwalks, graphic design, motion graphics, smell generation and smell diffusion, all united by mapmaking” 

A 2015 story on “Mapping Your City’s Smells” discusses some of her work, specifically for London, where they developed a ‘dictionary’ of urban smells, “…including less pleasant odors (“exhaust,” “manure,” “trash,” “putrid,” and “vomit” among them) and downright lovely-sounding ones (“lavender,” “fruity,” “BBQ,” and “baked,” for example).”  An aroma wheel developed by the team, captures the complexity of these smells.

From this, they used words in geotagged social media posts to capture a spatial picture of these elements, then mapped them based on concentrations in a Pollock-esque composition showing bad smells along red tones and nature smells in greens.  As noted:  “The researchers envision these maps being used in a variety of ways. Urban planners, they suggest, can use them to figure out which areas of the city smell the worst—and then consider using air-flow manipulation, green spaces, and pedestrian-friendly streets to change them. Maybe computer scientists will one day create a wayfinding app that gives users the most pleasant-smelling path to their destination. Or maybe city officials will be inspired to use social media data to more consistently monitor how their residents are being affected by smells—and by the pollution that creates it.”

An online map of this data also exists from McLeans collaborators Daniele Quercia, Rossano Schifanella, and Luca Maria Aiello, under the auspices of goodCitylife.

Smelly Maps provides an interactive version of the data for London, with some additional Info about this: “Think about your nose. Now think about big data. You probably didn’t realize it, but your nose is a big data machine. Humans are able to potentially discriminate more than thousands different odors. On one hand, we have our big data nose; on the other hand, we have city officials and urban planners who deal only with the management of less than ten bad odors out of a trillion. Why this negative and oversimplified perspective?  Smell is simply hard to measure.  SmellyMaps have recently proposed a new way of capturing the entire urban smellscape from social media data (i.e., tags on Flickr pictures or tweets). Cities are victims of a discipline’s negative perspective, only bad odors have been considered. The SmellyMaps project aims at disrupting this negative view and, as a consequence, being able to celebrate the complex smells of our cities.”  

Zooming in, you get a breakdown on the relative smell density and dominant smell in a dashboard style.

On the interactive side, a smellwalk project from 2014 for Amsterdam gives a good overview of the process, where multiple people walk and record information, with “Over 650 smells were detected by 44 people undertaking 10 smellwalks over a period of 4 days in April 2013. Based on written descriptions from the smellwalkers, 50 broad categories were identified. Both frequently-mentioned and curious smells feature on the map.”

She provides a short description of the results, discussing her expectation of cannabis instead replace with the reality of waffles, spices, herring, laundry, flowers and leaves detected by participants.

“Dots mark the origins of the smells, concentric circles indicate their range and the warped contours allude to potential smell drift in the north- and south-westerley winds encountered on the days of the smellwalks. It is estimated that humans have the capacity to discriminate up to 1 trillion smells and our experience is highly individual; to walk and sniff is to know.”

The color legend breaks down specific dominant smells (both frequently-mentioned and ‘curious) derived from the 650 smells, and a subset of the 50 categories.

The graphical quality of these maps amplifies the the experiential quality, which also I believe makes them more engaging to wider audiences of designers and planners.  The magnitude lines offer an opportunity to zoom in on some specific comments displayed in an engaging way.

A video of this Smellmap Amsterdam is worth a look also:

The 2017 New Yorker article “The Graphic Designer Who Maps the World’s Cities By Smell” shows a more localized example, as the author, guided by a kit she downloaded from McLean’s site, later mapped by McLean herself in Greenwich Village.  One of McLean’s own earlier endeavors looked at some specific blocks in New York, with a hyperlocal exercise,inspired by another article from New York Magazine ‘The Smelliest Block in New York‘.

The work blending art and science is a great model, and the representation offers some good lessons for mapping less concrete elements in the urban landscape.  The further parallel with hidden hydrology is in being able to interpret the unseen, as McLean mentions in the Atlas Obscura post, ““Participants are often surprised about how many odors can be detected if you really pay attention to smell,” McLean says. “Humans can differentiate a trillion different smells but we breathe about 24,000 times a day. Much of it can easily go unnoticed.” “

Victoria Henshaw

Another pioneer in the field is Victoria Henshaw, who sadly passed away in 2014. She provided another strong voice in the field of smell, authoring a 2013 book on the subject, Urban Smellscapes: Understanding and designing city smell environments, which was “…contributing towards the wider research agenda regarding how people sensually experience urban environments. It is the first of its kind in examining the role of smell specifically in contemporary experiences and perceptions of English towns and cities, highlighting the perception of urban smellscapes as inter-related with place perception, and describing odour’s contribution towards overall sense of place.”

An urban planner by training and an academic, Henshaw wrote on the topic at her blog Smell and the City, which, along with her book left a wonderful trove of info on the topic. An interview in Wired UK “Odour map seeks to save endangered smells‘ hints at an oft-mentioned theme in any writing around the subject: that while we scrub the cities of the bad smells, we also lose the essence of what makes places unique and special.

As mentioned by Henshaw: “”The approach to town-centre management has always been about sterilisation,” she says. “We’ve become so unused to strong smells that we now have adverse reactions to them.”  This disassociation is both the target as well as the opportunity to tap into unrealized sensory design opportunities, as we gain more understanding of the impacts.  One such method as the ability to reroute ventilation systems “to the front of restaurants and entertainment venues — with the intention of attracting more customers,” which ostensibly captures the essence and vitality of a food stall in Barcelona, from her site.

There’s a mention as well of a Global Smell Map that seems to be no longer viable as it doesn’t have any info.   A later article by Henshaw as well from 2014 ‘Don’t Turn Up Your Nose at the City in Summer” focuses the nose on New York, which for her was ‘The season of smell”, where smell becomes a factor in the original city grid layout to “maximize the benefits of westerly winds to dissipate the supposedly deadly miasmas thought to spread disease…” as well as industrial pasts, even long after the smoke stacks go cold, mentioning that “In London’s Olympic Village, for example, the main stadium was built on a former industrial zone — and when it rains, locals report detecting the smell of soap seeping from the site of an old factory.”

She mentions the sociology of smell as well, mentioning external issues like waste-treatment facilities and their smelly impacts often being located in poorer areas. “Smell also provides a sociological map of the city. Poorer people tend to have less control over their smell environments.”  The experience of smell-walks and close observations of senses, provides a new way of seeing and understanding places, and although sometimes foul, Henshaw’s advice is sound:

“But don’t hold your nose. Teach yourself to parse the city’s odors and you will find a new dimension of urban experience opening up before you. Accept the olfactory.”

McLean and Henshaw, along with a cast of others also helped co-edit the recent literature on the subject in the 2018 book  “Designing with Smell – Practices, Techniques and Challenges”, which offers “case studies from around the world, highlighting the current use of smell in different cutting-edge design and artistic practices…” [with] “…an emphasis on spatial design in numerous forms and interpretations – in the street, the studio, the theatre or exhibition space, as well as the representation of spatial relationships with smell.”

As mentioned, this detour into the realm of senses and smells may seem counter to the investigation of hidden hydrology, but these examples connect the hidden to the physical world through exploration, and also provide compelling ways of using these investigations of place while presenting graphic information that is compelling, interactive, and data-rich.  Next we will dive into another sensory exploration, that of soundscapes.
