Mapping Potential Crp Land And Determining Crp Profitability In Lancaster County, Jamie Pesek
Mapping Potential Crp Land And Determining Crp Profitability In Lancaster County, Jamie Pesek
Department of Environmental Studies: Undergraduate Student Theses
Annually 17 tons of soil is lost due to the erosion of agriculture land. A majority of the soil lost is fertile topsoil, which can render the land unproductive. The Conservation Reserve Program (CRP) was enacted to reduce the high erosion rates on agriculture land by giving landowners a monetary incentive to let their land lay idle and allow the soil to regenerate. Although there is awareness of the benefits of CRP, little effort has been put toward delineating CRP eligible land. In this project, Geographical Information Systems were used to map CRP eligible land in Lancaster County, Nebraska based …
Assessing Flood Inundation Mapping With The Use Of A Dem And Gis Along The Missouri River At Sioux City, Iowa, Kathryn A. Pfaffle
Assessing Flood Inundation Mapping With The Use Of A Dem And Gis Along The Missouri River At Sioux City, Iowa, Kathryn A. Pfaffle
Department of Environmental Studies: Undergraduate Student Theses
There are various methods that are used to predict flood inundation. The U.S. Army Corps of Engineers provided inundation maps for the 2011 Missouri River flood event that did not utilized aerial photo imagery. This study assesses the suitability of using a digital elevation model (DEM) in combination with aerial photo imagery within a geographic information system to predict flood inundation mapping along the Missouri River in Sioux City, Iowa. GPS data was collected during the height of this flood event in order to validate the positional accuracy of the DEM. Using the GPS receiver’s accuracy standards to determine the …
Distribution Of Trace Elements In Cumberland River Basin Reservoir Sediments, Laura Mahoney Benneyworth
Distribution Of Trace Elements In Cumberland River Basin Reservoir Sediments, Laura Mahoney Benneyworth
Masters Theses & Specialist Projects
The U.S. Army Corps of Engineers, Nashville District, maintains ten reservoirs in the Cumberland River Basin in Kentucky and Tennessee, and has been monitoring sediment chemistry in the reservoirs since 1994. The purpose of this study is to evaluate the sediment data collected from the reservoirs from 1994 to 2010 to determine if there are any spatial patterns of the trace elements: arsenic, beryllium, cadmium, chromium, copper, lead, mercury, nickel, and zinc. The results indicated that trace element levels were consistent with national baseline concentrations measured by the U.S. Geological Survey. Center Hill reservoir had the greatest number of trace …
Shoreline Evolution: Surry County, Virginia James River Shorelines, Donna A. Milligan, Christine A. Wilcox, C. Scott Hardaway Jr.
Shoreline Evolution: Surry County, Virginia James River Shorelines, Donna A. Milligan, Christine A. Wilcox, C. Scott Hardaway Jr.
Reports
Surry County is situated on the southern shore of the James River (Figure 1). The County has 168 miles of shoreline along the James River, Upper Chippokes Creek and Grays Creek. Through time, the County’s shoreline has evolved, and determining the rates and patterns of shore change provides the basis to know how a particular coast has changed through time and how it might proceed in the future . Along Chesapeake Bay’s estuarine shores, winds, waves, tides and currents shape and modify coastlines by eroding, transporting and depositing sediments.
The purpose of this report is to document how the shore …
Colonial Beach State Of The Beach Report: 2011, Donna A. Milligan, C. Scott Hardaway Jr., Christine Wilcox
Colonial Beach State Of The Beach Report: 2011, Donna A. Milligan, C. Scott Hardaway Jr., Christine Wilcox
Reports
The Town of Colonial Beach occupies a peninsula between the Potomac River and Monroe Bay. Approximately 2.5 miles of the shoreline is publicly-owned. Two areas on the Potomac River have been enhanced as recreational beaches for swimming and sunbathing. Central Beach is located just south of the Town Pier and is the main recreational beach. Castlewood Beach is south of Central Beach near the entrance to Monroe Bay. Mean tide range is 1.64 ft while the spring range 1.94 ft (NOAA,2011).
Specific shore change is addressed at Central Beach and Castlewood Beach through recent beach profiles. Beach profilestaken in January …

Shoreline Evolution: City Of Hampton, Virginia Chesapeake Bay, Back River, And Hampton River Shorelines, Donna A. Milligan, Christine Wilcox, C. Scott Hardaway Jr., Mary C. Cox
Reports
The City of Hampton has about 95 miles of tidal shoreline along Chesapeake Bay, Hampton Roads, Back River, and Hampton River (Figure 1). Through time, the City’s shoreline has evolved, and determining the rates and patterns of shore change provides the basis to know how a particular coast has changed through time and how it might proceed in the future. Along Chesapeake Bay’s estuarine shores, winds, waves, tides and currents shape and modify coastlines by eroding, transporting and depositing sediments. The purpose of this report is to document how the shore zone of City of Hampton has evolved since 1937. …
Gis Data: Northampton County, Virginia Tidal Marsh Inventory, Marcia Berman, Harry Berquist, Sharon Killeen, Carl Hershner, Karinna Nunez, Karen Reay, Tamia Rudnicky, Daniel E. Schatt
Gis Data: Northampton County, Virginia Tidal Marsh Inventory, Marcia Berman, Harry Berquist, Sharon Killeen, Carl Hershner, Karinna Nunez, Karen Reay, Tamia Rudnicky, Daniel E. Schatt
Data
The 2012 Tidal Marsh Inventory update for Northampton County, Virginia was generated using on-screen digitizing techniques in the most recent version of ArcGIS® - ArcMap while viewing conditions observed in the most recent imagery from the Virginia Base Mapping Program (VBMP). Dominant plant community types were primarily determined during field surveys from shallow-draft boats moving along the shoreline. Land-based surveys were performed in some locations. One shapefile is developed that portrays tidal marsh areas represented as polygons. A metadata file accompanies the shapefile to define attribute accuracy, data development, and any use restrictions that pertain to the data.
