Barrier Removal Is A Strategy For Climate Resilience, Sarah E. Null, William Bosen, Gregory Goodrum

Watershed Sciences Faculty Publications

Millions of dams and in-stream barriers have been built worldwide to manage water supply, reduce flood risk, generate hydropower, and support recreation, navigation, and road infrastructure. The National Aquatic Barrier Inventory estimates over 550,000 dams and over 298,000 road-related barriers that fragment streams in the United States¹. As dams age and as droughts and floods become more intense, some dams and barriers have become problems, for example, by outliving their useful life, presenting safety concerns to communities, and impacting ecosystems, especially in a changing climate. These dams – the ones that present safety concerns due to their age …

Groundwater Flooding On Highways In The Nebraska Sandhills: Applying Remote Sensing, Precipitation And Groundwater Modeling To Determine Depth, Cause And Frequency, Aaron R. Mittelstet

Nebraska Department of Transportation: Research Reports

Climate change significantly impacts infrastructure sustainability, particularly through shifts in precipitation patterns, intensity, and duration. These precipitation dynamics may increase the occurrence of surface water and groundwater flooding. Groundwater in the Nebraska Sand Hills (NSH), including the thickest portions of the High Plains Aquifer, extends close to the land surface in interdunal areas, making the NSH vulnerable to groundwater flooding. Recent events involving heavy precipitation, snow melt, and rising groundwater levels have caused prolonged highway flooding, disrupting transportation networks. This study estimates groundwater flood inundation depth, duration and frequency in the highways of NSH using remote sensing techniques and groundwater …

Power Optimized Co-Registration Of Multispectral And Thermal Cameras For Real-Time Urban Pluvial Flood Monitoring, Fatemeh Rezaei

Theses - ALL

Urban pluvial flooding occurs when local precipitation intensity exceeds the capacity of natural and engineered drainage systems, resulting in dangerous and highly localized inundation that is not captured by traditional stream gaging networks. While satellite imagery and flood maps support regional-scale flood management, a critical gap remains in the real-time, spatially continuous, in-situ monitoring of urban surface flooding. To address this monitoring gap, we develop a low-power, camera-based distributed sensor network flood mapping platform, Urban Flood Observation Network (UFO-Net), featuring two co-mounted sensors: a multispectral optical (capturing RGB and Near-Infrared) and a long-wave infrared (thermal) camera. A five-band image (RGB, …

Ecomuseums are holistic organizations that occupy landscapes, are responsive to community needs, conserve in situ heritage, and incorporate sustainability along with community development. The ecomuseum movement came from a need for holistic heritage management that disengaged with conventional museology and created space for communities to engage with their heritage in ways that promote community identity. This thesis analyzes the Calling Lakes Ecomuseum and how it utilizes the ecomuseum concept alongside environmental sustainability. Both semi-structured interviews and place-based field observations were used …

Convergence Research For Microplastic Pollution At The Watershed Scale, Heejun Chang, Elise Granek, Amanda Gannon, Jordyn M. Wolfand, Janice Brahney

Watershed Sciences Faculty Publications

Microplastics are found in Earth's atmosphere, lithosphere, hydrosphere, pedosphere, and ecosphere. While there is a growing interest and need to solve this grand challenge in both the academic and policy realms, few have engaged with academics, policymakers, and community partners to co-identify the problem, co-design research, and co-produce knowledge in tackling this issue. Using a convergence research framework, we investigated the perception of microplastic pollution among different end users, delivered educational materials to K-12 teachers and practitioners, and identified key sampling points for assessing environmental microplastic concentrations in the Columbia River Basin, United States. Three community partner workshops identified regional …

Watersmart Farms - Desalination: Inventory And Analysis, Ela Wendell, Abdulla Rasheed, Sharmina Begum, Vaibhav Patel, Goruck Soubans, John K. Ruprecht

Natural resources commissioned reports

A drying climate means traditional water supply resources of farms in southern Western Australia are frequently unable to meet agricultural production demands. However, extensive, untapped sources of brackish or moderately saline water ( <   20,000mg/L total dissolved solids (TDS) are present in nearly all agricultural areas experiencing water shortages. In response, a small, yet increasing, number of farms have privately financed and installed small-scale desalination units to treat locally sourced, salt-impaired water. This approach not only provides a new source of freshwater to the farm portfolio, but is unaffected by changing climatic and weather conditions. Since the majority of the early adopters of on-farm desalination draw the salt-impaired water from groundwater bores, the technology implementation also mitigates local salinization of agricultural land due to groundwater rise, while decreasing reliance on the heavily subsidized, centralized water supply schemes operated by Water Corporation (WC).

The WaterSmart Farms Desalination (WSFD) project was undertaken to assess the nature and performance of existing, small-scale, on-farm desalination systems, including their economics, sustainability, availability, and weaknesses; and to assess these decentralized systems’ applicability and uncertainties for broader application on farms throughout southern Western Australia. The project was undertaken by three major partners, WA Department of Primary Industries and Region Development (DPIRD), WC, and the Harry Butler …
