First Year Morphological Evolution of an Artificial Berm at Fort Myers Beach, Florida.

摘要

Maintenance dredging is a common practice in inlets and channels for navigation. As a part of regional sediment management, the dredged material is often used for nearby shore protection. One method is placing sand directly on the adjacent beach. The other is placement of a nearshore berm, i.e., to add sediment to the littoral system and/or act as a breakwater to dissipate wave energy and slow erosion (Allison and Pollock, 1993). Compared to beach fill, berm nourishment may have the advantage of being less costly with more lenient restrictions on the dredged material.
