A Method for Estimating Long-Term Erosion Rates from a Long-Term Rise in Water Level.

摘要

A method is presented for estimating long-term erosion rates resulting from a rise in sea level. The method is based on Bruun's (1962) method with an exponential curve fitted to the offshore beach profile. The exponential profile establishes the beach profile closure depth beyond which it is assumed waves do not move sand. An example problem using sea level rise data of Hicks (1973) illustrates application of the technique. (Author)
