Abstract:

Dunes act as a primary coastal defense against inundation in the Netherlands and the Dutch Government has devoted considerable effort towards development of reliable procedures for the design of safe dune systems. Current design methods are summarized in TAW (1984). Coastal engineering activities in the U.S., on the other hand, have focused on design of beach nourishment projects for purposes of both storm protection and recreation. In fact, many U.S. beach nourishment projects have concentrated on placement of sand seaward of existing dune lines with little consideration given to construction of protective dunes. In this paper, Dutch probabilistic design methodologies are applied to the design of a protective dune system for portions of the shoreline fronting the U.S. Navy's Fleet Combat Training Center, Atlantic (FCTCLANT) at Dam Neck, Virginia.
