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.

Tangier Island, Virginia Shoreline Management Plan For The West Coast Of The Uppards, C. Scott Hardaway Jr.

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 and …
