Quantifying The Effects Of Land Use Change On Stream Ecosystems For Use In Ecological Risk Assessment, Katherine Sciera
Quantifying The Effects Of Land Use Change On Stream Ecosystems For Use In Ecological Risk Assessment, Katherine Sciera
All Dissertations
Land disturbance often results in a cascade of physical and chemical stressors to aquatic ecosystems which can impact their biotic integrity. This study examined three developing watersheds near Greenville, SC to evaluate the quantitative relationships between the physical stressors associated with land use alterations and biotic integrity. More specifically, the objectives of this study were to 1) quantify the mechanisms of aquatic ecosystem degradation in streams impacted by watershed urbanization, 2) demonstrate the use of quantitative relationships among the physical, chemical, and biological stressors associated with land use change in an established ecological risk assessment framework, and 3) identify the …

Portland Me: Affordable Housing V. Open Space, Patrick Wright, Brett Richardson, Richard Barringer
Planning
Amid an acknowledged “affordable housing crisis”, a first-time developer approaches the City to release part of a tax-acquired property, promising a smart-growth development that would provide sorely needed starter homes for working families. The case highlights the complications of balancing competing interests in Portland ME. It shows where rational planning fails in the presence of strong neighborhood opposition, a disjointed city staff structure, and the absence of political will among City Councilors. It highlights the need for champions within local government when a project evokes competing interests. It demonstrates the extent to which “words matter” to policy outcomes, and who …
Discriminating Between Biological And Hydrological Controls Of Hyporheic Denitrification Across A Land Use Gradient In Nine Western Wyoming Streams, Andrew Kenneth Myers
Discriminating Between Biological And Hydrological Controls Of Hyporheic Denitrification Across A Land Use Gradient In Nine Western Wyoming Streams, Andrew Kenneth Myers
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
I studied nine streams near Grand Teton National Park, Wyoming, covering a land use gradient (urban, agricultural, and forested) to assess influences of land use on denitrification rates and hyporheic exchange. I hypothesized denitrification in the hyporheic zone is governed by availability of chemical substrates and hydrologic transport. I tested this hypothesis by coupling measurements of denitrification potentials in hyporheic sediments with a 2-storage zone solute transport model. Denitrification potentials were lowest on average in hyporheic sediments from forested streams and highest from agricultural streams. Modeling results suggest, on average, agricultural sites are transport-limited by having the slowest exchange rate …

Planning
Closure of the Brunswick Naval Air Station in 2011 will have profound economic impacts on the entire mid-coast Maine region of Maine, with an estimated loss of 6,500 jobs and $330 million annual income. Throughout the Base Realignment and Closure process, Brunswick, the region, and the State of Maine followed federal rules and developed the federally-funded Brunswick Local Redevelopment Authority (BLRA) to plan for reuse of the 3300 acre base. In its planning process, the BLRA adhered to a number of well thought-out Guiding Principles, including the use of extensive public participation and the consideration of “smart growth” principles and …

Land Use And Water Quality Characterization Of Boeuf Basin, La, Joseph Wesley Leblanc
Land Use And Water Quality Characterization Of Boeuf Basin, La, Joseph Wesley Leblanc
LSU Master's Theses
The three primary goals of this project were to establish the ambient background of water quality in the Lake Boeuf basin in southeast Louisiana; establish land use patterns in the basin and the relation to water quality; and develop a preliminary plan to improve water quality through the use of best management practices and wetland assimilation. Urban and agricultural acreage borders the basin and runoff from these lands forces loadings of nutrients into the adjacent canals where they become channelized and ultimately exit the Boeuf Basin into Lac des Allemandes. From September 2007 until February 2008, water sampling occurred monthly …
