Abstract:
Keelung Harbor, which is the most important center of sea freight in northern Taiwan, suffers from deteriorating urban development due to limited land supply. A dilemma arose from the Asahikawa River and the Tianliao River fronts, which evolved from cultural landscapes to buried and truncated rivers. This research was aimed at resolving the urban dilemma of the two adjacent rivers through a dialogue between the physical and augmented interaction of fabrics in three scenarios: GIS to AR, AR to GIS, and both. The physical dynamics were used to trace development chronologically by the area and length assessed from historical maps of hydrogeography, architecture, and the railroad. The augmented dynamics involved AR-based simulations and comparisons in terms of skyline overlay, fabric substitution, and fabric disposition. The dynamics involved AR models made by UAV images and 3D drawings. The assessments and simulations determined the key event in Keelung history when the Asahikawa River was leveled up. The dilemma verified from the augmented dynamics facilitated comprehension of the evolvement of the physical dynamics. With the assistance of AR and GIS, we concluded that the specific instance of riverfront reconstruction was an important landmark of meta-relationship.

Abstract:
Microplastics (MPs), commonly defined as particles less than 5 mm, are a persistent ubiquitous anthropogenic contaminant that can be found in every environment, making it a global environmental, health, and socioeconomic problem. Due to their high surface area, MPs adsorb toxic pollutants that become bioavailable to organisms upon ingestion as they are often mistaken for food leading to biomagnification (Bule et al., 2020). The sampling area represents the lower part of the Krka River Estuary and is under direct anthropogenic influence from the city of Šibenik runoff waters, nautical and communal ports, city harbor, tourism, mariculture, and fishing. Estuaries and harbors have been recognized as hotspots and transfer pathways for MPs primarily because of the vicinity of the urban environment that emits contaminants from various sources (Miller et al., 2021). The main focus of this research was to determine MPs size, shape, color, surface area, and abundance in surface water using volume-reduced samples collected by a net. Laboratory protocol included sieving, wet peroxidation (H2O2), density separation (saturated NaCl solution), sonication, and filtration. Filter papers were then visually inspected for MPs. Image processing and measurements were carried out with ImageJ/Fiji open-source software.

Abstract:
In this study, the main water body of remote sensing image was extracted with the maximum likelihood algorithm of ENVI software based on Qinzhou's remote sensing images 2008 and 2011. From the remote sensing images, it was found that the area of the water body was greatly reduced, and also the water body has been polluted differently. In this paper, the urgent environmental protections of Qinzhou's main rivers are analyzed in view of the reduced water body, and also some suggestions on water body conservation are proposed. Overview of Qinzhou Qinzhou is located between V20°52 and 22°41 N, and 107°27 and 109°56 S. The total area of Qinzhou is about 10842.73 square kilometers. It is in the corner of the South China Sea, and is the core base of the north gulf economic region. Thus, it takes an absolute advantage in logistics. The national patriotism education bases for elementary and middle schools in Qinzhou are the former homes of two national heroes (Yongfu LIU, and Zicai FENG). In Qinzhou, there is a coastline of more than 520 kilometers, and many excellently natural harbors such as Qinzhou Port, Longmen Port, Shajing Port, and Siluo Port are available here. Also, there are abundant product advantages. The climate is hot. Many rivers and water reservoirs are available. Soil and plants are flourishing greatly. Since the new century, Qinzhou government as well as the governments of all counties greatly invest Qinzhou, carry out urban and rural clean engineering, urban infrastructure project construction, and agricultural preferential policies, and establish multi-form and multi-dimensional economic and technical cooperation with foreign and domestic companies, in which business is easy to process and the procedures are simple to handle. In 2013, the high-speed rail has brought a new era to Qinzhou. Qinzhou's advantages in climate conditions, rain conditions, and water resources Qinzhou is located in the subtropical zone and features a transitional marine monsoon climate. The overall terrain forms are mountains, hills, terraces plains, and coastal mud flats from northwest to southeast. From east to north, the main mountain is LIUWAN Mountain. From west to north, the main mountain is SHIWAN Mountain. The annual average temperature is 22°C; the absolute maximum temperature was 37.5°C (July 28, 1968), and the absolute lowest temperature was-1.8°C (January 12, 1955). The average annual rainfall is about 1600mm; the average sunshine period is about 1800 hours, and the frost-free period is more than 350 days. The solar radiation amount is 104.6~108.8 kilocalorie/cm2; the annual sunshine duration is 1633.6~1801.4 hours; the annual average temperature is 21.4°C~22°C; the annual total accumulated temperature is 7800°C~ 8200°C. The average frost-free period of previous years was 329~354 days. The water resources advantages of Qinzhou include humid temperature, abundant rain, and annual rainfall of 1600mm~1900mm. Major rivers include Qinjiang, Maolingjiang, Nanliujiang, and Dafengjiang, and the annual runoff is 11.728 billion cubic meters. The gross storage capacity of small, middle, and large reservoirs has reached 805 million cubic meters. Qinzhou's remote sensing image and the river remote sensing images of recent years The water yield of the main rivers in Qinzhou is abundant and falls greatly, so the hydropower resource is rich. The rivers in Qinzhou are small and medium-sized, own a large quantity of flow, and flow into the sea, but do not form drainage.

Abstract:
Izmir Bay is one of the great natural areas of the Mediterranean and compares well with similar coastal areas in the world. Izmir which is the main urban area around the Bay is an important industrial, commercial and cultural focal point. It has the second biggest harbour and is the third largest city in the country. The Izmir metropolitan area has experienced rapid population increase which placed an intense pressure on the environment of the bay, housing, infrastructure and social services. The main sources of pollution in the bay are domestic and industrial effluents which account for 50% of the observed organic pollution. Rivers discharging to the Izmir Bay carry mostly industrial discharges. The main forms of pollution in the Izmir Bay are organic pollution, nutrients, pathogenic organisms and toxic material carried by rivers. Scientific evidence suggests if no pollution control measures are taken immediately pollution in the Bay will soon reach a critical level leading to the collapse in the ecosystem. With this understanding Izmir Sewerage and Stream Control Project which foresees the reestablishment of the Bay's water quality was started in 1983. The preliminary assessment of the costs and benefits of the project suggests that the benefits of the proposed pollution control system could significantly outweigh the costs of the control measures by a factor of about eight.

Abstract:
Urban transformation is directly related to the planning, design and use of a series of urban infrastructures, from streets to highways, from pedestrian, bicycle, bus or train lines and their connecting transport hubs to rivers, canals or harbor facilities. They play an essential role in the transformation of the urban fabric. Recent societal changes, especially in developing countries, demanding higher mobility and urban interaction, influence the used planning and design strategies to transform or extend urbanized areas by planning or renewing these infrastructures. However, its relationship to the surrounding urban fabric, more specifically the collective spaces it constitutes at the level of the streetscape, is not always an initial or integral part of providing these infrastructures. In many cases, the urban fabric is wrapped around or fragmented by these infrastructural projects, causing scale contrasts and struggle to integrate within, generating processes of misappropriation or misuse. Especially in developing contexts, new infrastructures are often planned and built in a fast way, rarely considering the qualities of the existing urban fabric. During the last decades, research on planning and design models related to the building or integrating of urban infrastructures has been developed and tested via specialised disciplinary approaches to produce insights on the relationship urban infrastructures have with the surrounding urban fabric (Secchi, 2013; Hasan, et. al. 2010; Shannon and Smets, 2009; De Maulder, 2008; Hillier, 1996;). However, additional in-depth research is needed to achieve critical insights on the relationship of infrastructures and their direct environments, starting from their constituent streetscapes - considering the level of the street that defines the perception and use by the inhabitants at an intermediate scale. This paper focuses on an ongoing research project in Addis Ababa (Ethiopia), where different visions and models of urban growth are at stake (Figure 1). The recent increase of (foreign) investment in major infrastructures, changes the city's streetscapes drastically. This large scale and formal approach of installing high speed trains, Light Rail Transit's (LRT) or expanded highways and ring roads, to stimulate urban growth, contrasts with the daily routines of the proper citizens that move around by walking or by means of mini buses, both adding to the informal qualities of the city's streetscapes. Within this multi-centred capital, the location of built and planned housing projects, commercial centres, administrative or commercial high rises is studied in relation to the present infrastructural axes and questions models of proximity, accessibility and permeability.

Abstract:
ABSTRACT The (U.S.) National Academy of Sciences’ National Research Council (NRC) has completed the third in a series (spanning three decades) of comprehensive examinations of the inputs, fates, and effects of petroleum in the ocean. This most recent study, entitled Oil in the Sea III: Inputs, Fates and Effects (NRC 2002) indicates that changes in petroleum handling practices and production techniques, as well as the introduction of double-hulled tankers, have reduced the size, frequency, and total volume of marine spills over the last decade. As suggested by earlier studies, natural seeps, land-based run off, and atmospheric deposition from marine and terrestrial sources continue to represent the majority of petroleum input to the marine environment. In addition to world-wide estimates, the report includes estimates of the total inputs to both inshore and offshore waters along 17 zones along North American. New estimates indicate that the overall amount of petroleum released to the marine environment may be lower than earlier thought (1.3 million tonnes per year [2002] versus 3.2 million tonnes per year [1985]). The overall lower estimates reflect more accurate and complete supporting information as well as real reductions attributable to advances in marine transportation and oil and gas production techniques. Spillage from vessels from 1990 to 1999 was less than one-third of the spillage during the prior decade, and, despite increased production, reductions in releases during oil and gas exploration and production have been dramatic as well. Chronic releases during consumption of petroleum, which include urban runoff, polluted rivers, and discharges from commercial and recreational marine vessels, contribute 70 percent of the anthropogenic load to the marine environment, worldwide. These releases can pose significant risks to the sensitive coastal environments where they most often occur. Insights have been made from long-term studies of sites of major spills or polluted harbors, but to a large degree the significance (in terms of environmental damage) of the large inputs from land-based sources or other chronic releases is not known. Recent studies, however, suggest that polycyclic aromatic hydrocarbons (PAH), even in low concentrations, can have a deleterious effect on marine biota.

Abstract:
This essay examines the implications of rapid technological and economic change, or what economist Joseph Schumpeter called “creative destruction,” for the urban environment. Taking the Chicago River Harbor as a case study, it argues that industrial capitalism was marked by fundamental spatial and environmental contradictions that resulted in the frequent destruction and reinvention of urban landscapes. The essay shows how transformations in the Great Lakes shipping industry and the rise of the steel industry rendered Chicago River Harbor infrastructure obsolete. That obsolescence, in turn, sparked a public debate over whether the port should be retrofitted or if the river should be harnessed for different uses. So many stakeholders—streetcar companies, commuters, City Beautiful advocates, and sanitary engineers—had conflicting ideas about the use of the river that it was practically impossible to retrofit the port. The resulting decline of industrial freight traffic on the Chicago River enabled urban planner Daniel Burnham to reinvent the riverfront as a site of leisure and consumption.

Abstract:
Classification systems have been developed over the last century as a tool to aid managers in the preservation, conservation, enhancement and management of rivers. The classification systems developed to date have been designed to differentiate between relatively unimpacted, mainly rural rivers. Urban rivers typically show poor water quality and biological diversity, and so most current classification systems tend to group urban rivers into a single “poor” category. In this paper we describe a hierarchical framework for recording information about urban rivers that allows a more sensitive description of these rivers enabling subdivision into several classes according to the purpose of the classification. The different levels in the hierarchy, the types of attributes that are to be recorded at each level, and the relational database structure for storing the data are described. The 100-500 m river stretch level in the hierarchy relates to the engineered modification of urban rivers and is the key to their classification. An example classification at this scale illustrates a link between engineering modification, bank and bed materials and the number and diversity of physical habitats present. This classification underlines the importance of adopting a hierarchy of nested spatial scales for data collection, classification and interpretation since it illustrates a clear link between characteristics at the stretch scale and at the finer habitat scale. The classification also illustrates the varied nature of urban rivers and the fact that even quite heavily engineered stretches can contain a diversity of habitat types.

Abstract:
This project was an exercise in aligning my intuition, community experience, and design sensitivities under the pretext of an architectural expression. My desire was to work endogenously, or out of my home environment, on a project that had no clear programmatic or formal requirements or limitations. I began by assessing a prevalent issue in my home town (a connection between the river and the town center) both from the top down and the bottom up. Throughout, I sought to challenge my preconceived notions of what might be, and allow a design process to emerge out of the layers of information I had absorbed as a participant in this holistic landscape. Inflection and change became a driving force in this pared down design process, and through them came a working territory that framed the programmatic and formal specificities of the South River P.O.R.T.

Full text
Abstract:
Fine substrate sediments are considered to be important in the management of urban river systems. Urban construction activities have been reported to increase sediment loads causing the temporary siltation of channel substrates within the urban area. Nevertheless fine sediment derived from urban areas frequently carry toxic material well in excess of background concentration levels. While the soluble phase of heavy metals and the importance of their association with suspended sediment has received considerable attention, longer term studies of fine urban river-bed sediments are limited. Furthermore studies of heavy pollutants in active stream sediments, below mine waste tips, have shown the channel substrate can provide a long term store for heavy metals in association with fine sediments. This thesis investigates the variety of impacts that urbanisation has upon the sedimentation of gravel bed rivers. A freeze coring technique and infIltration baskets have been used to study the textural-geochemical properties of fme matrix sediment and its development within an urban river-bed framework, within and below a number of contrasting urban catchments in the U.K. Complex urban hydrological and sedimentological regimes are shown to have a variable influence upon matrix sedimentation. The actual volume of matrix present within the urbanised substrate is influenced by the degree of urbanisation within the catchment. Furthermore this sediment is finer in size and associated heavy metal concentrations are well in excess of natural background levels. Although heavy metal levels do correlate slightly with textural characteristics, the presence of maximum concentrations at depth in the substrate indicate possible mobilisation of metals within the urbanised river-bed. The temporal behaviour of matrix development within an urbanised substrate is shown to differ from natural river-beds. Despite high suspended sediment concentrations the magnitude of the potential rate of supply is lower, by 50 percent, and dominated by organic material. This sediment also contains elevated heavy metal cocnentrations. This contrasts to the inorganic sediment ingress of natural river substrates. It is concluded that fine matrix sediments within urban gravel bed rivers should be at least of concern to public health engineers, water authorities and conservationists.

Full text
Abstract:
Subsurface oil and surface seep samples from the Niger Delta Nigeria, Tano and Cape Three Points Basins in Ghana, and the Orcadian Basin in Scotland were analysed using an organic geochemistry approach. Source organofacies, oil thermal maturity and the effect of alteration processes were evaluated, with the aim of developing a better understanding of the origin, nature and type of petroleum present. Biomarker analyses suggested that undegraded oils are found with biodegraded oils with a range of levels of biodegradation in the Niger Delta. On the commonly used Peters and Moldowan scale of biodegradation, the samples rank between PM level 0 and 7. The Ghanaian and Scottish oils and seeps showed a range of biodegradation levels between PM level 2 and 7. Biodegradation appeared to be the major control on the composition and physical properties of the oils and seeps from Niger Delta and Ghana while there is evidence that a stage of water washing was important for the Scottish seeps. Key aspects of the biodegradation process were reflected in the variable occurrence of hopanoids and other biomarkers. 25-Norhopanes were detected in all samples biodegraded in subsurface reservoirs but absent in seeps degraded at surface conditions. This was observed for both the Ghanaian and Nigeria samples. The inverse relationship of hopane to 25- norhopanes in the Niger Delta is presented for the first time. This evidence supports the hypothesis that 25-norhopanes are a product of hopane demethylation. Furthermore a pathway for the formation of 25-norhopane from 25-norhopanoic acid by decarboxylation is evidence by nature of the covariation in relative concentration of these compounds. Seeps from Scotland show that only moderate levels of biodegradation (PM 3) have significantly reduced monoaromatic and triaromatic steroids abundances. The most likely cause for this is by water washing at surface conditions. Reservoir temperature and oil charge histories appeared to have had a significant influence on the extent of biodegradation in the Niger Delta. The late migration of oil from deeper hotter subsurface regions to shallow reservoirs accounts for the presence of undegraded oils amidst the biodegraded oils in the Niger Delta.

Full text
Abstract:
Many urban rivers receive significant inputs of metal-contaminated sediments from their catchments. Their restoration has the potential to increase the deposition and accumulation of these sediments from greater sediment supply and increased channel hydraulic complexity, creating a store of metals which could have negative impacts upon ecosystems and human health. Macrophytes often establish in restored channels and have the potential to stabilise these sediments and uptake metals through processes of phytoremediation, thus reducing the risk of the accumulated sediments becoming a source of metals. This thesis investigates the effects of river restoration upon sedimentation patterns and the interactions between macrophytes and sediments in terms of sediment trapping, stabilisation and metal uptake within urban river systems. At a reach scale, greater finer sediment deposition and the accumulation of sediment around in-channel vegetation was found within restored stretches of tributaries of the River Thames London, reflecting sediment availability and hydraulic conditions. These sediments were important in terms of greater metal storage within stretches, and along with gravels showed particularly high metal concentrations. Interactions between macrophytes, sediment and flow were investigated within the urban-influenced River Blackwater, Surrey. At the stand scale, the common emergent Sparganium erectum was found to significantly reduce flow velocities, accumulate fine sediments and retain them over winter. Research on individual plants revealed that, although three common emergent macrophytes (Sparganium erectum, Typha latifolia and Phalaris arundinacea) did not significantly phytoremediate metal contaminated sediments through metal uptake or bioconcentration, the reinforcement and stabilisation of these accumulated sediments (particularly by Sparganium erectum and Typha latifolia) and the creation of anoxic sediment conditions which strongly bind metals, were important in reducing the risk of metal mobilisation from the sediments. These macrophyte sediment interactions illustrate the great potential of using emergent macrophytes in the restoration and management of urban rivers with metal contaminated sediments.

Governance of international rivers is characterized by complex institutional arrangements aimed at minimizing uncertainty and making it difficult for participants to avoid their responsibilities. However, as new information emerges, new impacts of activities on rivers are identified, new stakeholders emerge and new technologies are developed, international river management agreements and treaties may have to be modified. At the very least, the implementation of the governance arrangements may need to be adjusted. Most river governance agreements are the product of extended negotiations in which the parties work hard to codify and define the details. This makes the task of modifying the agreements, or even of implementing them in new ways, difficult. In some cases the details and format of the institutional arrangements make it hard to respond to the changing nature of the social and ecological problems that emerge over time. In other cases they do not. This raises the question, "Why and how do efforts to formulate international water resource arrangements that bring together countries with common resource management concerns but conflicting interests, limit or support needed adjustments?" This dissertation explores what I call the conventional versus the adaptive approach to international river basin governance. The former makes it hard to adjust over time; the latter, less so. Climate change appears to be increasing the need for flexibility in river basin governance. So, I compare how institutional arrangements that reflect a conventional approach to uncertainty and conflict impede the ability of water governance participants to make necessary adjustments, while institutional arrangements that reflect an adaptive approach are more likely to provide the flexibility that is required. Case studies of the navigation and water protection regimes for the Danube River and the benefit sharing agreement for the Nile River provide the basis for my conclusions.

Urban development and engineering works have resulted in the majority of rivers that drain urban areas being severely degraded, both ecologically and in terms of their potential amenity value. This dissertation explores the reasons for this "spiral of degradation" and it describes the ecological and social impacts on rivers caused by urban development, channelisation and canalisation. It then suggests possible measures to mitigate the impacts at the levels of the catchment, floodplain and river channel. The present cycle of degradation of urban rivers in the Cape Metropolitan Area (and elsewhere) can be halted. In addition, where degradation has already occurred, mitigation and rehabilitation are possible and could restore some of the lost conservation and ecological values, as well as the potential amenity, recreation and education functions. Early colonisation of Cape Town by Europeans inflicted severe impacts on the rivers surrounding and passing through the city. These included: catchment degradation, water abstraction, the disposal of unpurified sewage and industrial effluents, removal of riparian forests, clearing of instream vegetation and the draining of wetlands. During the 20111 century, many urban rivers have been "improved" by straightening or confining within rectangular concrete-lined canals in order to protect urban development in flood-prone areas. The unquestioning faith in technology during this period and the attitude that human ingenuity could "improve nature" are now regarded by the scientific community, together with some local and regional authorities and informed members of the public, as mistakes that resulted in ecological and environmental degradation. These technical solutions merely treated the symptoms of the problem without recognising, let alone attempting to treat, the causes, that is poor catchment and floodplain management. However, there is still a public demand for canalisation of the remaining "natural" rivers in the greater Cape Town area and beyond. At the same time, there has been an increase in environmental awareness, as well as a growing appreciation of the value of holistic and multi-objective planning in the engineering and planning professions. This dissertation aims to assess the impacts of urbanisation, channelisation and canalisation on the aquatic ecosystem and socio-economic environment of urban rivers, and to develop possible measures to mitigate these impacts.

Abstract:
Washington, D.C., like many older U.S. cities, suffers the woes of rapid urbanization and aging infrastructure. The cityâ s combined sewer and stormwater system dumps millions of gallons of raw sewage into the Anacostia and Potomac Rivers over 70 times annually during significant rain events. While many groups, both public and private, attempt to clean the river, billions of dollars are still necessary over several years to remedy the combined sewer overfl ow (CSO) problem alone. Current plans for a solution include constructing large underground storage tanks that store millions of gallons of wastewater during overflow periods. Washington, however, once had a network of waterways that naturally drained the Federal City. At least three major stream systemsâ the Tiber Creek, James Creek and Slash Runâ and over 30 springs flowed within the boundaries of the emerging capital. The waterways, now buried, were victims of urbanization, and flow now only underground, wreaking havoc on foundations and basements and causing sewer backups and flooding. Can a historically-driven investigation of these buried channels lend credence to the resurrection in some form of a network of surface stormwater channels, separate from the municipal sewage system, to solve the cityâ s sewage overflow crisis? The following study is an initial exploration of the re-establishment of waterways through Washington with the purpose of improving the current storm sewer overflow dilemma and exploring the potential urban amenities that they could provide as part of a stormwater management plan for the year 2110.

Abstract:
Public participation has the potential to either enhance urban development outcomes or entrench disagreement and frustration. A major challenge for policy-makers is how to understand and then respond to the narratives, metaphors and arguments contributed by stakeholders. In analysing the public participation process for the Two Rivers Urban Park (TRUP) in Cape Town, this research applies argumentative discourse analysis to capture and analyse multiple dimensions of stakeholder contributions. Arguments, and other linguistic features, were linked to themes distilled from the data. Associating and matching these themes to stakeholder groups identified discourse coalitions. The analysis supports the claim that the development of TRUP involves more than merely a technical discussion. The metaphors, stories and arguments used by participants to discuss the development of TRUP refer to it as an emblematic issue for the development of the city, its history, the history of South Africa and globalisation across the world. The discourse coalitions identified illuminate diverging ideas of how cities ought to respond to the environment, the private sector and residents. Without this knowledge government cannot hope to respond to stakeholders in a manner they will find satisfactory.

Abstract:
During the lockdown imposed due to the first wave of the coronavirus disease (COVID-19) pandemic, there were several media reports of citizens flouting the lockdown rules in the United States. Upon closer investigation it was found that the rules were flouted mostly so that people could spend time outdoors in natural environments. This exemplifies the role of the natural environment as a panacea to the mental stress created by pandemics. River ecosystems are perhaps the greatest natural feature of any city. Efficient management of urban rivers, therefore, is strongly correlated to crisis management during pandemics like COVID-19.

Desiderati, Christopher. Carli Creek Regional Water Quality Project: Assessing Water Quality Improvement at an Urban Stormwater Constructed Wetland. Portland State University, 2022. http://dx.doi.org/10.15760/mem.78.

Full text
Abstract:
Stormwater management is an ongoing challenge in the United States and the world at-large. As state and municipal agencies grapple with conflicting interests like encouraging land development, complying with permits to control stormwater discharges, “urban stream syndrome” effects, and charges to steward natural resources for the long-term, some agencies may turn to constructed wetlands (CWs) as aesthetically pleasing and functional natural analogs for attenuating pollution delivered by stormwater runoff to rivers and streams. Constructed wetlands retain pollutants via common physical, physicochemical, and biological principles such as settling, adsorption, or plant and algae uptake. The efficacy of constructed wetlands for pollutant attenuation varies depending on many factors such as flow rate, pollutant loading, maintenance practices, and design features. In 2018, the culmination of efforts by Clackamas Water Environment Services and others led to the opening of the Carli Creek Water Quality Project, a 15-acre constructed wetland adjacent to Carli Creek, a small, 3500-ft tributary of the Clackamas River in Clackamas County, OR. The combined creek and constructed wetland drain an industrialized, 438-acre, impervious catchment. The wetland consists of a linear series of a detention pond and three bioretention treatment cells, contributing a combined 1.8 acres of treatment area (a 1:243 ratio with the catchment) and 3.3 acre-feet of total runoff storage. In this study, raw pollutant concentrations in runoff were evaluated against International Stormwater BMP database benchmarks and Oregon Water Quality Criteria. Concentration and mass-based reductions were calculated for 10 specific pollutants and compared to daily precipitation totals from a nearby precipitation station. Mass-based reductions were generally higher for all pollutants, largely due to runoff volume reduction on the treatment terrace. Concentration-based reductions were highly variable, and suggested export of certain pollutants (e.g., ammonia), even when reporting on a mass-basis. Mass load reductions on the terrace for total dissolved solids, nitrate+nitrite, dissolved lead, and dissolved copper were 43.3 ± 10%, 41.9 ± 10%, 36.6 ± 13%, and 43.2 ± 16%, respectively. E. coli saw log-reductions ranging from -1.3 — 3.0 on the terrace, and -1.0 — 1.8 in the creek. Oregon Water Quality Criteria were consistently met at the two in-stream sites on Carli Creek for E. coli with one exception, and for dissolved cadmium, lead, zinc, and copper (with one exception for copper). However, dissolved total solids at the downstream Carli Creek site was above the Willamette River guidance value 100 mg/L roughly 71% of the time. The precipitation record during the study was useful for explaining certain pollutant reductions, as several mechanisms are driven by physical processes, however it was not definitive. The historic rain/snow/ice event in mid-February 2021 appeared to impact mass-based reductions for all metals. Qualitatively, precipitation seemed to have the largest effect on nutrient dynamics, specifically ammonia-nitrogen. Determining exact mechanisms of pollutant removals was outside the scope of this study. An improved flow record, more targeted storm sampling, or more comprehensive nutrient profiles could aid in answering important questions on dominant mechanisms of this new constructed wetland. This study is useful in establishing a framework and baseline for understanding this one-of-a-kind regional stormwater treatment project and pursuing further questions in the future.

Full text
Abstract:
Interdepartmental Memorandum of Understanding (IMOU) 5170 between Natural Resources Canada (NRCAN), the Geological Survey of Canada (GSC) and Transport Canada Innovation Centre (TC-IC) aims to gain new insight into slow-moving landslides, and the influence of climate change, through testing conventional and emerging monitoring technologies. IMOU 5107 focuses on strategically important sections of the national railway network in the Thompson River valley, British Columbia (BC), and the Assiniboine River valley along the borders of Manitoba (MN) and Saskatchewan (SK). Results of this research are applicable elsewhere in Canada (e.g., the urban-rural-industrial landscapes of the Okanagan Valley, BC), and around the world where slow-moving landslides and climate change are adversely affecting critical socio-economic infrastructure. Open File 8931 outlines landslide mapping and changedetection monitoring protocols based on the successes of IMOU 5170 and ICL-IPL Project 202 in BC. In this region, ice sheets, glaciers, permafrost, rivers and oceans, high relief, and biogeoclimatic characteristics contribute to produce distinctive rapid and slow-moving landslide assemblages that have the potential to impact railway infrastructure and operations. Bedrock and drift-covered slopes along the transportation corridors are prone to mass wasting when favourable conditions exist. In high-relief mountainous areas, rapidly moving landslides include rock and debris avalanches, rock and debris falls, debris flows and torrents, and lahars. In areas with moderate to low relief, rapid to slow mass movements include rockslides and slumps, debris or earth slides and slumps, and earth flows. Slow-moving landslides include rock glaciers, rock and soil creep, solifluction, and lateral spreads in bedrock and surficial deposits. Research efforts lead to a better understanding of how geological conditions, extreme weather events and climate change influence landslide activity along the national railway corridor. Combining field-based landslide investigation with multi-year geospatial and in-situ time-series monitoring leads to a more resilient railway national transportation network able to meet Canada's future socioeconomic needs, while ensuring protection of the environment and resource-based communities from landslides related to extreme weather events and climate change. InSAR only measures displacement in the east-west orientation, whereas UAV and RTK-GNSS change-detection surveys capture full displacement vectors. RTK-GNSS do not provide spatial coverage, whereas InSAR and UAV surveys do. In addition, InSAR and UAV photogrammetry cannot map underwater, whereas boat-mounted bathymetric surveys reveal information on channel morphology and riverbed composition. Remote sensing datasets, consolidated in a geographic information system, capture the spatial relationships between landslide distribution and specific terrain features, at-risk infrastructure, and the environmental conditions expected to correlate with landslide incidence and magnitude. Reliable real-time monitoring solutions for critical railway infrastructure (e.g., ballast, tracks, retaining walls, tunnels, and bridges) able to withstand the harsh environmental conditions of Canada are highlighted. The provision of fundamental geoscience and baseline geospatial monitoring allows stakeholders to develop robust risk tolerance, remediation, and mitigation strategies to maintain the resilience and accessibility of critical transportation infrastructure, while also protecting the natural environment, community stakeholders, and Canadian economy. We propose a best-practice solution involving three levels of investigation to describe the form and function of the wide range of rapid and slow-moving landslides occurring across Canada that is also applicable elsewhere. Research activities for 2022 to 2025 are presented by way of conclusion.
