The pressureforce effects induced by an explosively generated dispersive wave train on a vertical barrier were studied in the laboratory. The barrier was in the surf zone on a beach having a 114 slope. The induced force was found to have two phases 1 An impact phase, and 2 a slowly varying phase which is mostly hydrostatic. The ratio of peak impact force to maximum hydrostatic force was 3.36. Example problems utilizing the test data are presented. The results suggest that wave induced impact is most serious for breakwaters and seawalls constructed of several courses of large blocks which rely solely upon friction for shear resistance between courses.
