Abstract: In a series of papers, the authors have described a new method for analyzing and predicting damage progression on rubble mound structures. Empirical equations with coefficients determined with data from a series of small-scale physical model stability tests using depth limited waves, with each test consisting of a sequence of storms, are described. These equations provide a method for predicting eroded area and its alongshore variability, and the eroded profile extent, depth, and alongshore variability for breakwater and revetment trunks. The equations apply to both sequences of storms and constant wave conditions. These papers are summarized herein for use in design.
