Abstract
Design waves and water depth at a construction site are important factors in a seawall design, but the seawall design excludes factors such as wind speed and direction. It is easy to image that a gale increases the volume of water that gets over a seawall more than an expected overtopping rate. In order to achieve a safety land use on a coastal area, the wind speed and direction should be included in the seawall design process to estimate the wave overtopping rate properly. This study aims to clear the effect of wind speed on wave overtopping phenomenon to construct a methodology that could evaluate the wave overtopping rate under the gale condition. Furthermore, this study evaluates the effect of a wave dissipating work with lower crown height to reduce the wave overtopping rate on Flared shaped seawall less than an upright seawall covered with wave dissipating blocks under the gale condition.
