Reports
Shoreline evolution is the change in the shore zone through time. Along the shores of Chesapeake Bay, it is a process and response system. The processes at work include winds, waves, tides and currents which shape and modify coastlines by eroding, transporting and depositing sediments. The shore line is commonly plotted and measured to provide a rate of change, but it is as important to understand the geomorphic patterns of change. Shore analysis provides the basis to know how a particular coast has changed through time and how it might proceed in the future. The purpose of this data report …
Aquatic Habitat Mapping Within The Obed Wild And Scenic River For Threatened And Endangered Species Habitat Delineation, Joseph Ross Candlish
Aquatic Habitat Mapping Within The Obed Wild And Scenic River For Threatened And Endangered Species Habitat Delineation, Joseph Ross Candlish
Masters Theses
There is a need to define a more efficient and accurate approach to aquatic habitat mapping. Traditional approaches have focused on intense biological/non-biological sampling and observation analysis within specific and restrained scales. Therefore, an underwater video mapping system (UVMS) has been developed in efforts to identify federally protected aquatic species’ habitats within the Obed Wild and Scenic River (OBRI). The UVMS kayak apparatus provides georeferenced video footage correlated with GPS (global positioning systems) for GIS (geographic information systems) mapping applications. Based on its fluvial and geomorphological trends, OBRI was dissected quantitatively and integrated into databases for species-specific GIS habitat queries. …
Analysis Of Streamflow In The St. Croix River: A Hydrologic Model, Stephanie A. Kleinschmidt
Analysis Of Streamflow In The St. Croix River: A Hydrologic Model, Stephanie A. Kleinschmidt
Geography Honors Projects
This project assesses how streamflow is affected by anthropogenic changes to the environment, looking specifically at the St. Croix River Basin. In 2004 the United States Geologic Survey (USGS) published a report on streamflow in the St. Croix River at two gaging stations: Danbury and St. Croix Falls. The streamflow at the upstream station near Danbury, Wisconsin remained stable over time, while an increase was observed at the station in St. Croix Falls, Wisconsin further downstream. In order to evaluate this disparity, this project utilizes a GIS hydrologic model to analyze the factors expected to be influencing the flow rate. …
Shoreline Evolution: City Of Poquoson, Virginia Poquoson River, Chesapeake Bay, And Back River Shorelines, Donna A. Milligan, Kevin P. O'Brien, Christine Wilcox, C. Scott Hardaway Jr.
Shoreline Evolution: City Of Poquoson, Virginia Poquoson River, Chesapeake Bay, And Back River Shorelines, Donna A. Milligan, Kevin P. O'Brien, Christine Wilcox, C. Scott Hardaway Jr.
Reports
The purpose of this data report is to document how the shore zone of Poquoson has evolved since 1937. Aerial imagery was taken for most of the Bay region beginning that year, and can be used to assess the geomorphic nature of shore change. Aerial imagery shows how the coast has changed, how beaches, dunes, bars, and spits have grown or decayed, how barriers have breached, how inlets have changed course, and how one shore type has displaced another or has not changed at all. Shore change is a natural process but, quite often, the impacts of man through shore …
