Spatial Analysis Of A Chesapeake Bay Sub-Watershed: How Land Use And Precipitation Patterns Impact Water Quality In The James River, Kristina Delia
Spatial Analysis Of A Chesapeake Bay Sub-Watershed: How Land Use And Precipitation Patterns Impact Water Quality In The James River, Kristina Delia
Theses and Dissertations
As land cover throughout the Chesapeake Bay watershed is modified and climate patterns alter, changes in runoff occur which can impact water quality. A study was conducted using the Soil and Water Assessment Tool (SWAT) for the James River watershed in Virginia, the southernmost tributary of the Chesapeake Bay, for 1986 to 2018. A comparison of land cover changes throughout that time frame was included in the analysis. Land cover data was derived from satellite imagery with values extracted using Geographic Information System (GIS) analysis. The SWAT model was run within the web-based Hydrologic and Water Quality System (HAWQS). The …
Evaluating The Unequal Impacts Of Hurricane Harvey: A Critical Gis Analysis In Systems Of Governmental Risk Assessment And Mitigation, Mustafa Ansari Monk
Evaluating The Unequal Impacts Of Hurricane Harvey: A Critical Gis Analysis In Systems Of Governmental Risk Assessment And Mitigation, Mustafa Ansari Monk
Theses and Dissertations
This thesis uses flooding driven by Hurricane Harvey in 2017 and a history of inundation in Houston, Texas to critique the systems of floodplain mapping through the National Flood Insurance Program (NFIP). The role of Geographic Information Systems becomes a subject of interest in the context of U.S governance and the role of property as a driving force in urban development. The shortcomings of existing systems of mitigation are examined through mappings that bring measures of risk, damage, and recovery into contrast with each other. Racial and economic inequality are integrated into the analysis through a deeper consideration of the …
Assessment Of Coastal Watershed Erosion Potential Using Geographic Information Systems And Expert Input For Decision Support, John H. Cartwright
Assessment Of Coastal Watershed Erosion Potential Using Geographic Information Systems And Expert Input For Decision Support, John H. Cartwright
Theses and Dissertations
Sediment is a major impairment in many streams and rivers in the drainage basins along the northern Gulf of Mexico. The use of geospatial technologies improves assessment and decision making for the management of environmental resources and conditions for coastal watersheds. This research focuses on the development of a conceptual qualitative model enhanced with expert input for the assessment of soil erosion potential in coastal watersheds. The conceptual model is built upon five layers (slope, precipitation, soil brightness or exposure, Kactor, and stream density) like those in a standard numerical soil loss model such as the Revised Universal Soil Loss …
