Wave Screening Performance Using Floating and Submerged Breakwaters

Abstract

In this study, the floating breakwater and the submerged breakwater are used together to achieve the strong point and to complement the weak point of the floating breakwater and submerged breakwater. Two-dimensional finite element method is used for the numerical analysis and the wave reflection ratio and the wave transmission ratio are analyzed. In case of using the floating breakwater and the submerged breakwater together, it screens waves more effectively than in case of using the floating breakwater or the submerged breakwater, separately. It also shows an effective wave screening on the long wave period and an advanced wave screening performance with low height of the submerged breakwater.
