Shoreline Evolution: City Of Chesapeake, Virginia Elizabeth River Shorelines Data Summary Report, Donna A. Milligan, Christine Wilcox, C. Scott Hardaway Jr.

Reports

City of Chesapeake is situated between the Cities of Norfolk and Portsmouth along several branches of the Elizabeth River (Figure 1). Because the City's shoreline is continually changing, determining where the shoreline was in the past, how far and how fast it is moving, and what factors drive shoreline change will help define where the shoreline will be going in the future. These rates and patterns of shore change along Chesapeake Bay’s estuarine shores will differ through time as winds, waves, tides and currents shape and modify coastlines by eroding, transporting and depositing sediments.

The purpose of this ...

Chemical And Toxicological Characterization Of The Upper York River, Virginia The Mattaponi And Pamunkey Rivers, Morris H. Roberts Jr., Mark Richards, Peter F. Delisle

Reports

This study describes the most extensive effort to characterize the chemistry, toxicology and community of the sediments of the Mattaponi and Pamunkey Rivers. This was accomplished using a study design modified to expand the number of stations occupied by reducing the cost of analyses by compositing replicate samples collected from each study site rather than performing toxicity tests on these samples individually. In previous studies, the variability in field replicate samples was equivalent to the variability in laboratory replicates. This design has long been used to analyze samples for various chemical contaminants as a cost savings endeavor. More ....

Tangier Island, Virginia Shoreline Management Plan For The West Coast Of The Uppards, Shoreline Studies Program, Virginia Institute Of Marine Science

Reports

Utilizing geo-rectified aerial photography from 1938, 1960, 1987, and 2001, shoreline change rates were determined along the Uppards. Shoreline change rates vary but are all erosional except for areas around the north end where sand bars come and go. In the area of concern between baseline stations 4000 and 4600, the rates of erosion have increased with time. Using the rate calculated from the 1938 to 2001 shorelines for station 4000, 16 ft/yr, the 400 ft marsh isthmus width between the shoreline and Toms Gut would breach in about 25 years. This would essentially break the Uppards in two ...

Sediments And Shallow Stratigraphy Of A Portion Of The Continental Shelf Of Southeastern Virginia, Carl H. Hobbs Iii Aug 1997

Sediments And Shallow Stratigraphy Of A Portion Of The Continental Shelf Of Southeastern Virginia, Carl H. Hobbs Iii

Reports

A network of high-resolution, seismic-reflection profiles and grab samples of the surficial sediments of the inner continental shelf of southeastern Virginia demonstrate that the Quaternary geology of the region is more complex than indicated by earlier studies. The spatial variability of the surficial sediments depicts active processes, such as outflow from Chesapeake Bay, as well as the underlying geology in outcrops of finer grained sediments near False Cape.

The complexity of the Quaternary geology results from large and small scale fluctuations in sea level. Individual, relatively large-scale, seismostratigraphic units are separated by erosional surfaces formed during the major changes in ...
