Study on wave reduction efficiency of foreshore submerged breakwater using mathematical models

Abstract

    Submerged breakwater has been popularity applied in many countries in the world as an active coastal protection solution. This type of structure reduces wave energy; restore and maintain shore,beach... This article refers to study results using BOUSSINESQ mathematical models that werevalidated with the results of wave flume physical model tests to analyze and evaluate the influence of parameters (submergence depth, crest width, structure slope, and foreshore slope) on wave reduction efficiency of foreshore submerged breakwater. Results showed that structure slope and foreshore slope do not have significant influence on wave reduction efficiency of the structure.

    Relative submergence depth and relative crest width play an decisive role on wave reduction efficiency of submerged breakwater. The study demonstrated fundamental processes and principlesof wave reduction efficiency of foreshore submerged breakwater, which are necessary for applying this type of structure in Vietnam.
