Effects Of Land Use On Riparian Corridors In Sonoma County, Marina Davies 2020 The University of San Francisco

Effects Of Land Use On Riparian Corridors In Sonoma County, Marina Davies

Master's Projects and Capstones

Riparian corridor protection through zoning ordinances is a common best management practice to protect riparian ecosystems and function. These zoning ordinances protect riparian ecosystems by establishing setback distances where land use activities are prohibited. While management of protected riparian corridors are widely studied, recommendations for riparian corridor width vary and are often site specific. The variability of corridor widths presents a challenge to riparian corridor implementation, in addition to balancing economic needs with natural resource protection. This study evaluates the effects of land use on riparian corridors and compares the Riparian Corridor Combining Zone ordinance in Sonoma County to other ...

Stream Restoration As A Method Of Improving Local Water Quality, Emily George 2020 University of Richmond

Stream Restoration As A Method Of Improving Local Water Quality, Emily George

Environmental Studies Senior Seminar Projects

Projects of stream restoration are a known Best Management Practice (BMP) to approach stormwater management, and have been adopted globally as a means of improving local hydrology. Urbanization has led to an increase in impervious surfaces, resulting in deteriorated streams, many of which are subject to stream restoration. Stormwater control measures (SCM), such as stream restoration, are considered to be a subset of green infrastructure as a method to reconnect streams with surrounding riparian areas, revitalize original hydrology, and support the local ecosystems. This paper looks into the viability of stream restoration as a way of improving water quality, focusing ...

Remediation Strategies To Reduce Heavy Metal Uptake In Lettuce Grown In Contaminated Urban Soil, Ryley Thomas

UCARE Research Products

Urban soils are increasingly used to produce food for local consumption, which requires at the same time management strategies that prevent the plant uptake of potentially present contaminants. This study was conducted to test different soil amendments for their ability to retain lead (Pb) and arsenic (As) within the soil matrix. The analyzed soil was taken from a potential community garden lot near a railroad in Lincoln, NE where elevated concentrations in Pb and As had been detected. Ponderosa pine biochar and spent coffee grounds were used as soil additives because of their documented chemical reactivity towards soil cations or ...


Assessing Residential Socioeconomic Factors Associated With Pollutant Releases Using Epa’S Toxic Release Inventory, Amanda Charette 2020 SUNY College of Environmental Science and Forestry

Assessing Residential Socioeconomic Factors Associated With Pollutant Releases Using Epa’S Toxic Release Inventory, Amanda Charette

Dissertations and Theses

It has been demonstrated that certain demographic groups – particularly minorities and low-income individuals – live disproportionately closer to polluting facilities. Therefore, we investigated the chemical releases from Toxic Release Inventory (TRI) facilities in four counties in Upstate New York (Albany, Erie, Monroe, and Onondaga Counties). Using hierarchal clustering, we created seven unique residential clusters from nine population demographics. We geocoded the polluting facilities into our residential clusters to determine if any demographic group was disproportionately exposed to the presence of TRI facilities. Next, the quantity, in pounds, of chemicals released were calculated, the chemicals released were weighted based upon their potential ...

Sediment Outflow Under Simulated Rainfall Conditions With Varying Geotechnical Properties, Pranjay Joshi, Akhilesh Kumar, P. V. Singh, Jahangeer Jahangeer

Daugherty Water for Food Global Institute: Faculty Publications

The vulnerability of soil toward erosion might be reduced by having a good vegetative cover over the soil surface, slope improvement, and improving soil properties so that it is not easily detached and transported. However, the establishment of proper vegetative cover is a long process because it takes time for seeds to germinate and attain maturity. As an alternative approach, if soil resistance was increased by increasing the shear strength of soil against erosive forces offered by eroding agents, the soil system would become capable of withstanding the detachment of its particles on the application of shear stress. To achieve ...

384— Chimney Swift Conservation Project, Brian Zapfel, Hiina Asami

GREAT Day

The Chimney Swift Project is a student team promoting conservation for Chimney Swifts, a species of small insectivorous bird found throughout the eastern United States and Canada during their breeding season. In a natural setting, Chimney Swifts nest in hollow trees which were common in the old-growth forests prominent in the United States before European colonization. Currently, Chimney Swifts population is on a steep decline primarily due to human caused habitat destruction. Overall, 75% of the population has been lost since 1970. Our project aims to promote the conservation of Chimney Swifts through the construction of a nesting tower and ...


Surveillance Of Microplastic Pollution In Central Virginia Freshwater Ecosystems, Alexandra Reddy 2020 Liberty University

Surveillance Of Microplastic Pollution In Central Virginia Freshwater Ecosystems, Alexandra Reddy

Senior Honors Theses

Aquatic organisms often mistake microplastic particulates (MP) as food and inadvertently ingest the particulates, which can biomagnify through the food chain. While MP ingestion is well-researched in the marine environment, little is known about microplastics in freshwater  ecosystems. This project explores MP occurrence in an ecologically significant freshwater invertebrate: crayfish. Crayfish from two Central Virginia streams are collected to identify MP in the digestive tracts and gill filaments, and characterize the MP using analytical chemistry techniques. It was determined that MP were present in the digestive tracts and gill filaments of crayfish collected from both streams, and that MP frequency ...
