Toward A Comprehensive Water Quality Model For The Chesapeake Bay Using Unstructured Grids, Xun Cai

Dissertations, Theses, and Masters Projects

Chesapeake Bay is one of the most productive ecosystems on the US east coast which supports various living resources and habitat, and therefore has significant impacts on human beings and ecosystem health. Developing the capability of accurately simulating the water quality condition in the Chesapeake Bay, such as seasonal hypoxia, phytoplankton production, and nutrient dynamics, helps to better understand the interactions of hydrodynamical and biochemical processes, and more importantly, to predict conditions under changing climate and human intervention. Currently, most Chesapeake Bay models use structured grids that lack the flexibility for local refinements to fit complex geometry over both large …

The Effects Of Sea Level Rise On Tidal Wetlands In The Lynnhaven River Watershed, Marcia Berman, Harry Berquist, Center For Coastal Resources Management, Virginia Institute Of Marine Science

Reports

This study classified tidal wetlands for the Lynnhaven Watershed using remote sensing techniques and high resolution imagery from 2007. This updated delineation of wetlands, was used in conjunction with a simplistic geospatial elevation model to quantify the potential loss of wetlands under various sea level rise scenarios.The study revealed that using conservative estimates of sea level rise, nearly all wetlands would be lost by the year 2100. Projecting sea level rise into the future can be considered speculative, nevertheless such predictions are necessary to begin managing for and planning for climate change impacts. Evidence from this study suggests that upland …

The Chesapeake Bay Breakwater Database Project Hurricane Isabel Impacts To Four Breakwater Systems, C. Scott Hardaway Jr., Donna A. Milligan, Christine A. Wilcox, Linda M. Meneghini, G. R. Thomas, Travis R. Comer

Reports

The Chesapeake Bay Breakwater Database is being developed by personnel in the Virginia Institute of Marine Science’s (VIMS) Shoreline Studies Program for the U.S. Army Corps of Engineers (COE) in order to:

1) document breakwater system performance around Chesapeake Bay relative to predictions

2) develop guidelines for breakwaters in sand limited and fetch limited systems such as estuaries, reservoirs, lakes and bays.

Tidal Wetland Contributions To Fecal Coliform Loads In Shellfish Growing Waters By Analysis Of Model Prediction Discrepancy, Jie. Huang

Dissertations, Theses, and Masters Projects

Fecal contamination in estuaries has become an increasing concern worldwide. The use of wetlands for wastewater treatment has expanded due to their natural ability to improve water quality by removing suspended sediments, nutrients, and fecal bacteria. In general, most of the removal occurs through deposition and accumulation in the wetland substrate. This would suggest that wetlands are effective filters for fecal coliform transported from terrestrial environments to surface waters. It has also been hypothesized, however, that wetlands may be an intermittent source of fecal coliform in tidal systems as a result of wildlife deposition and /or accumulation from terrestrial sources. …

Temporal And Spatial Variations In Chesapeake Bay Water Quality: A Video Data Report, Sarah E. Rennie, Bruce Neilson

Reports

Over the past two years we have been developing computer programs to investigate various scientific visualization techniques as applied to estuarine data. The original impetus was to be able to visualize the results of the three-dimensional hydrodynamic model under development at the Virginia Institute of Marine Science, College of William and Mary (VIMS). We quickly recognized the superior ability of certain graphic approaches, especially pseudocolor animation, to efficiently transmit a tremendous amount of information to the viewer, allowing the scientist to gain an insight into the dynamics of the data not otherwise available. We decided to apply this technique to …
