Abstract
The numerical analysis on the wave screening performance of the submerged breakwater with various crown widths is presented. The fluid motion is considered as linearized two dimensional potential flow and the finite element method is used to analyze the wave screening performance of the submerged breakwater. It is found that single-submerged breakwater with large crown width shows the most effective wave screening performance and single-submerged breakwater with small crown width also shows fairly good wave screening performance but its effectiveness is less than that of single-submerged breakwater with large crown width. However, double- or triple-submerged breakwater with small crown width shows more effective wave screening performance than that of single- or double-submerged breakwater with large crown width. It is expected that the submerged breakwater with small crown width is economical because it reduces the size of structure.
