Presentation of New Design of Perforated Half-Depth Wall Breakwater

Abstract

The present study aims to introduce a new lattice wall breaker. The wall of this breaker is made up of small PVC cubic elements (PVC). Each of these cuboid shapes (blocks) has two holes, which, when placed on each other and through the metal cable through them, blocks are woven together. In the present study, three models of structures (with different porosity percent) are evaluated by examining three wave heights and at least 10 periods of rotation in a depth of water and a constant nourishment depth of the structure. The results showed that the decrease of wave height by 50%, in the porosity of the wall is 15%. The behavior of each model of the structure against the waves was also justified by accurate examination of the shock wave power.
