The process involves physical modeling of this structure in the laboratory. The hole and wave parameters are varied to determine the breakwater performance. The results show that the transmission coefficient (<em>K<sub>T</sub></em>) value is reduced as the relative hole height (<em>h<sub>L</sub></em>/<em>d</em>) value is decreasing and the relative hole length (<em>B</em>/<em>L</em>) and wave steepness (<em>H</em>/<em>L</em>) values are increasing. The energy dissipation coefficient (<em>K<sub>D</sub></em>) value increases with an increment in <em>h<sub>L</sub></em>/<em>d</em>, <em>H</em>/<em>L</em>, and <em>B</em>/<em>L</em> but starts to decrease after reaching the maximum, which is the optimum <em>H</em><em> × B</em>/<em>L<sup>2</sup></em> value. This optimum value is found to be 0.0034(<em>h<sub>L</sub></em>/<em>d</em>)<sup>2.618</sup> depending on the (<em>h<sub>L</sub></em>/<em>d</em>) value, while the maximum <em>K<sub>D</sub></em> value is recorded to be 0.70.</p> ER -
