Abstract
Ocean waves have a large enough energy potential; the model's zigzag placement and the addition of a wave-concentrating collector on the Wave Catcher Shore Protection Dual-Slope (WCSP-DS) is an innovation and engineering technique to capture wave energy. This study aims to produce an increase in the height of the deformation wave and to find the effect of setting the structural model's layout and adding a focusing collector to the increase in overtopping discharge in WCSP-DS. 3D laboratory tests were carried out using a 1:20 model scale for the length, height, and depth scale. Variations in model structure parameters, namely freeboard height (Fb) five variations, focusing collector length (l) three variations; focusing collector width (b) 3 variations; vertical wall height (z) 0.35 m. The results showed that with the longer focusing collector in the three variations of the model's depth-related (d/z) and the three variations of the wave period (T), an increase in the height of the deformation wave (Hdef) in front of the model structure. The freeboard height (Fb) and the structure wavefront height (Hdef) significantly affect the overtopping discharge entering the reservoir. In zigzag model placement the average overtopping discharge entering the reservoir is 5.167 x 10-4 m³/s. The addition of one focusing collector can increase the overtopping discharge (Q) that enters the reservoir by 55.47%, and the addition of two focusing collectors can increase the overtopping discharge (Q) that enters the reservoir by 182.56%
