Stormwater To Groundwater: How California Can Increase Groundwater Storage And Build Climate Resilience., Emily M. Perales

Master's Projects and Capstones

California is predicted to have more intense and frequent changes in weather patterns within the next 50 years. Historical and current groundwater use for residential and agricultural use is unsustainable and is creating significant deficits in groundwater aquifers throughout the state. To better adapt to potential damages caused by atmospheric rivers, better stormwater management and capture could increase California’s Climate adaptability. This study is focused on the means and methods to capture stormwater and increase groundwater recharge. Nature-based infrastructure (NBI), or Green Infrastructure (GI), has been used in urban areas throughout the country to mitigate harmful stormwater effects by replicating …

Assessing Equity Of Green Infrastructure Strategies To Address Heat Vulnerability In Los Angeles Sustainable City Planning, Sophia N. La Herran

Master's Projects and Capstones

Urbanization has brought about many undesirable environmental changes, with extreme heat and urban heat island (UHI) effect being some of the most significant. In addition to the challenge of UHI effect and increase of extreme heat events, heat also disproportionately affects different types of urban populations with higher populations of minority and low-income residents, who are more exposed and have limited capacity to adapt to extreme. The increased vulnerability to heat faced by socially vulnerable communities can be linked to the inequalities in neighborhood level exposure to extreme heat events, underlying health conditions, workplace conditions, housing quality, and other lasting …

Underground Stormwater Treatment Performance In Urban Coastal Catchments: Case Study Of Baffle Boxes In The City Of Tampa, Awet Eyob Tsegay

USF Tampa Graduate Theses and Dissertations

In coastal urban regions, underground stormwater treatment units are suitable infrastructure options because they take less space where premium land is expensive. Even then, they should be accessible and ideally small enough to fit into existing stormwater networks. Since 2003, the City of Tampa and Florida’s Department of Transportation (FDOT) have installed 47 baffle boxes into the city’s stormwater pipe networks. Baffle boxes are underground stormwater treatment structures designed to capture sediments and floating debris. Since their deployment, many challenges regarding their practical sediment capturing performance was raised by the city.

The objective of this research was to evaluate the …

Efficacy Of Compost Amended Biofiltration Swales As Green Stormwater Infrastructure For Treatment Of Toxicants In Salish Sea Road Run-Off, Benjamin D. Leonard, Katherine T. Peter, Bowen W. Du, Edward Kolodziej, Nathaniel L. Scholz, John D. Stark, Jenifer K. Mcintyre

Salish Sea Ecosystem Conference

Biofiltration swales, or bioswales, use vegetated soil substrates to filter contaminants from stormwater, decrease sediment load, and reduce erosion. Following a storm, runoff moves slowly through the swale at a shallow depth. While stormwater is retained in the bioswales, pollutants are removed by the combined effects of filtration, infiltration, settling, and biotransformation. The system currently being evaluated at the Washington State University (WSU) Puyallup Research and Extension Center (PREC) uses compost to further enhance the ability of bioswales to remove toxicants. WSDOT has created guidelines for constructing compost amended biofiltration swales (CABS) and implemented a field test for CABS along …

An Integrated Environmental Analysis Framework For Multi-Functional Urban Food Production Utilizing Nutrient Recycling From Organic Waste Streams, William Kort

Theses and Dissertations

Increasing enthusiasm for local food, including urban agriculture, has piqued research interest in the tenets underlying perceived benefits of localizing food production. This study develops and demonstrates the application of a comprehensive framework for the life cycle environmental assessment of the utilization of urban organic wastes in urban agriculture, specifically fruit and vegetable production. Results indicate that this full “urban nutrient cycle” may have significant environmental benefits in terms of land area requirements, water use, wastewater generation, nutrient recovery, environmental contamination and green infrastructure potential, compared to more conventional methods of waste processing and food production.

Assessing Downstream Stormwater Impacts For Urban Watershed Planning, Johanna Meyer Pavlowsky

Masters Theses

"The urbanization of watersheds has caused debilitating effects to downstream aquatic ecosystems in catchments and streams. The implementation of green infrastructure (GI), such as permeable pavements and bioretention facilities, has been shown to alleviate these effects by both reducing runoff and mitigating pollutants; however, the implements are often not designed with a specific goal of water improvement. This study targets understanding a small, impaired urban watershed, and the benefits green infrastructure may have to provide environmental, social, and economic improvement to the watershed.

Monitoring And Modeling The Hydrological Performance Of Extensive Green Roof Systems, Joseph Seidl

Theses and Dissertations

Urban stormwater runoff causes many problems for watersheds located within large metropolitan areas, including such detrimental effects as flooding, erosion, pollution, and the increased risk of combined sewerage overflows. Increased amounts of impervious areas resulting from urban sprawl have also been shown to escalate stormwater flows, which exacerbates water management issues in these metropolitan areas. Water resource engineers have progressively turned toward green infrastructure to solve stormwater problems, and green roof systems represent one type of this green infrastructure. As of current, however, green roof systems are largely underused in as an effective stormwater management tool.

The major factor limiting …
