This report describes the methodology for computing coastal storm-induced water surface elevation versus frequency of occurrence relationships for the U.S. territory of American Samoa. Maximum inundation levels were -computed from a combination of representative tidal elevations, storm surge, wave-induced setup, ponding level on fringing reefs, and wave runup. The statistical approach taken to calculate frequency-of-occurrence relationships was the Empirical Simulation Technique, which applies historical wave information and a nearest neighbor technique for simulating random storm events. Each phase of the study is described in detail and study results are presented in tables.
