Abstract
The purpose of this study is to clarify how much vertical telescopic breakwater affects water level reduction in the event of a storm surge for the development of an evaluation method by using CADMAS-SURF/3D and STOC-ML. The velocity flow between the breakwaters corresponds to the theoretical value, which is evaluated based on water level difference. Therefore, the result indicates that the aperture can be reduced by around 1.0% when analyzing the breakwater with 7.2% aperture using STOC-ML. Because of this study, it is possible to obtain approximate water level reduction using dimensionless quantities including the conditions of wave, breakwater, and harbor.
