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.

Book Description
Analyses are presented of two-dimensional laboratory measurements of the forces induced by breaking waves on a vertical barrier placed on a plane with a one-to-ten slope. The deepwater wave heights ranged from 0.2 to 0.6 foot and their periods ranged from 1.9 to 3.3 seconds. The ratio between the depth of water in front of the barrier and the deepwater wave length was approximately 0.0115. The forces on the barrier in this study are usually characterized by a peak, which occurs immediately after the initial impact. The impulse of the peak is usually a small percentage of the cumulative impulse up to the time of momentum reversal. After this short-duration peak, the force decreases exponentially until after an appreciable part of the wave period - about one-sixth, depending on the wave steepness - when it rises again to a (second) maximum which occurs at the time of momentum reversal. This maximum in the force is approximately equal to the average force from the time of initial impact to the time of this maximum of rise (momentum reversal). (Author).
