Abstract:

A review of the beach nourishment fill performance literature reveals that the accepted and proven theories of beach fill performance can be categorized as either one-line models or analytic models. The models assume that the initial shoreline is approximately straight which makes application to irregular shorelines difficult. Except for recent developments in one-line models (for example Hanson, 1989), the incorporation of coastal structures into shoreline models has been limited. Therefore prediction of beach fill performance on beaches with existing structures has been very approximate. Beach fill performance studies (Dean, 1988) have shown that for typical open ocean wave climates, projects with a length less than approximately one mile are generally not feasible since they erode too quickly.
