Wave Dissipating Effect of a Swash Plate Type Submerged Breakwater (SURF) and its Design Method

Abstract

A new type of submerged breakwater, named SURF, has been developed. SURF is made up of a caisson with a top plate and several sills, and quite effective on the reduction of wave height in spite of it's small dimension. In this study, a mechanism of wave energy dissipation and, characteristics of transmission and left-lettlection coefficients are discussed based on the results from twodimensional model tests. Furthermore, the design method is proposed by using the experimental results.
