Analysis of Spatial and Temporal Shoreline Variations Along the United States Atlantic Coast.

摘要

In order to systematically measure shoreline erosion and storm surge penetration along extensive reaches of the United States Atlantic coast, a common-scale mapping method was developed using historical aerial photography as the data base. Aerial photography of the southern New Jersey coast covering four decades is used to demonstrate the methodology and to provide long-term baseline information on shoreline dynamics. The data sets include mean erosion rates and variance at 100-m intervals along the coast. Shoreline recession rates along the New Jersey coast are generally less than 1 m/yr. but for several locations rates exceed 5 m/yr., and they vary considerably both within and between the island segments of the New Jersey coast.
