Abstract: Two shoreline modification projects were designed that use a new application of an old idea to provide erosion protection and improve shoreline access and aesthetics. The innovation consists of a buried revetment. In both cases, the gravel face of the water-facing slope is the primary defense against wave erosion. Should the wave energy increase beyond the ability of the gravel slope to cope, erosion can continue to the buried revetment. The buried revetment is designed to arrest local shoreline erosion from storm-generated waves until a maintenance program is initiated to restore the shore or beach to its natural-looking, original, and low-energy equilibrium condition. The revetment can be buried by filling over an existing revetment at the shoreline or by trenching in a new revetment. A brief description of the two projects and a discussion of the buried revetment concept is presented. General design and permitting guidelines are discussed. The types of revetment materials available and the advantages and disadvantages of each type are outlined.
