Wave Pressure on Seawall
In order to clarify the characteristics of the bore pressure due to tsunami, experiments and three-dimensional numerical simulations are carried out. In the experiments, the vertical distributions of pressure were measured on the center line of the upstream surface of the wall. With increasing distance from the bed, the pressure decreases and then increases slightly. Then, the pressure decreases to a negative value. After that, the pressure approaches zero. In the numerical experiments, the characteristic pressure profiles near the bed can be reproduced. However, the negative pressure could not be reproduced in any cases carried out in this study.
