Book Description
The characteristics of dispersive water waves--wave celerity, water particle velocity, and wave deformation--were studied in the laboratory in a region adjacent to the shoreline on a beach which has a 1:14 slope. The waves were generated by immersing a plunger at a distance from the shoreline in water of constant depth. A numerical scheme for the calculation of mean water particle velocity in the horizontal direction was developed according to the principle of continuity. This scheme is highly stable and is suitable for small computer facilities such as the IBM 1620. Methods for the estimation of wave forces and pressures on a vertical barrier, mounted as a seawall, were developed. The methods are based on momentum consideration and require knowledge of the water particle velocity in the horizontal direction and the shape of the incident wave. (Author).

Book Description
The pressure/force 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 1:14 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.
