The impacts of such faecal contamination from boats is potentially high in marinas where boats are often kept and occupied for varying periods of time. The nature and extent of such faecal contamination from boats in marinas of different design and use is still inadequately understood. In this study the levels of faecal coliform (FC) bacteria were measured in the waters of a confined and an open water marina over a 6 d period encompassing a holiday weekend. Levels of FC rose with increasing occupancy by boats and boaters during the study period and then declined again. FC levels were higher in waters of a confined or basin marina than in waters of an open or unconfined marina. In both confined and open water marinas, FC levels were highest in water samples collected near boats but they also became elevated on occasion in water samples taken a distance of 305 m from boats. Concentrations of FC in marina waters exceeded the standards and guidelines for shell-fishing and primary contact recreation waters. Therefore, greater consideration of human health risks from enteric microbes in marina waters and shellfish is recommended.}, number={3}, journal={WATER SCIENCE AND TECHNOLOGY}, author={Sobsey, MD and Perdue, R and Overton, M and Fisher, J}, year={2003}, pages={199–204} } @article{judge_overton_fisher_2003, title={Vulnerability indicators for coastal dunes}, volume={129}, DOI={10.1061/(ASCE)0733-950X(2003)129:6(270)}, abstractNote={This paper describes the development of a new parameter to characterize dune vulnerability to storm-induced erosion. Existing indicators of dune erosion vulnerability are examined, including expected cross-sectional erosion values calculated using storm characteristics. We extract a series of 110 pre- and poststorm profiles at cross-shore transects, spaced at approximately 300 m alongshore on digital terrain models of a North Carolina barrier island. Dune failure and survival are designated based on a percentage of the cross-sectional area eroded—50% or greater erosion indicates failure, less than 50% erosion, survival. Crest height does not prove to be an effective predictor of dune vulnerability. Existing cross-sectional area based parameters show some success in predicting erosion vulnerability. We improve the dune failure and survival prediction success rate using a new parameter, a surrogate moment of inertia, the erosion resistance.}, number={6}, journal={Journal of Waterway, Port, Coastal and Ocean Engineering}, author={Judge, E.

In estuaries with large influences by tides or storm surges, the velocity is controlled by the dynamic change in water level. These changes at the ocean boundary together with the upland runoff drive the hydrodynamics of the system. Because the ocean water surface is a function of the characteristics of storm surges, the velocity is likewise similarly affected. Thus, in order to determine the velocity at the proposed project site, a simulation of the hydrodynamics is required using the ocean storm surge as the driving boundary condition. A problem arises, however, in defining an appropriate method to correctly describe the ocean boundary. This paper describes three methods for determining the boundary condition based upon historical and stochastic representations of tropical storms (hurricanes) at the ocean boundary of a particular estuary. Each of the three methods is applied to the Indian River estuary in Delaware. For a simple and conservative approach, the single design hydrograph method yields good results for the Indian River example.}, number={6}, journal={Journal of Hydraulic Engineering}, author={Edge, B.
