Wave Climate and Littoral Sediment Transport Study for Virginia Beach, VA - Rudee Inlet to Cape Henry, Hydraulic Model Study
2008
Briggs, Michael J. | Thompson, Edward F.
The Norfolk District is preparing an Environmental Assessment for the use of sand sources off the coast of Cape Henry for future maintenance of the Virginia Beach, VA, shoreline. The primary purpose is to maintain a buffer for hurricane protection for structures landward of the existing beach. The Cape Henry Borrow Area is being considered as a sand source. The plan borrow scenario involves removing approximately 34.2 M cu yd of material from the borrow area over a period of 50 years. The study provided wave climate and potential longshore transport information and analysis for two bathymetric cases: existing bathymetry and planned excavation from the Cape Henry Borrow Area. These two cases bracket the range of expected conditions over the next 50 years and enable assessment of potential project impacts on littoral transport patterns along adjacent beaches during this time frame.
