Numerical simulation of regular wave transmission coefficient over submerged breakwater

open access: yesShuili Shuiyun Gongcheng Xuebao, 2017
Wave transmission coefficient over a submerged breakwater is the main index to measure the wave weakened capacity of the submerged breakwater. A numerical wave flume is established by the MIKE21-BW model based on Boussinesq-type equations, and a ...
