Incident and reflected wave separation on wave propagation over breakwater

Abstract

Abstract The quantification of the reflection waves is of paramount importance in coastal engineering. The reflection wave that affects the incoming waves over time will gradually affect the calculation of the transmitted waves after passing through a submerged breakwater. In this study, the reflection waves that affect the incident waves will be separated so that the appropriate transmission coefficient is obtained. The accuracy of this separation method of the incident waves and reflections will be evaluated using a numerical scheme. The numerical scheme that we use here is a staggered finite volume method. A small error in the comparison indicates the wave separation process is good enough to produce a reflection coefficient following the numerical results.
