Alternatives for Control of Shoreline Erosion at Fort Eustis, Virginia

Abstract : This study gives alternatives for control of shoreline erosion at thirteen sites at Fort Eustis, Virginia. Water waves are the major cause of erosion in the study area with design wave heights from 1.0 to 4.0 ft. Design still-water levels are +5.6 ft MLW for the 25-year return period event and +6.2 ft MLW for the 50-year return period event. Advantages and disadvantages of the various types of protection are given along with a sketch for each structure- site combination. Alternatives for shore protection include drainage control- diversion of runoff at top of bank, vegetation; riprap revetments, broken concrete revetments, bulkheads (w or w/o toe protection) - used auto tires and timber post, gabions (vinyl-coated wire), treated timber, steel sheetpiling, steel h-piles and railroad ties with cap, retard-used auto tire post and beach nourishment-truck in sand.
