Wave Transformation on Wave Catcher Shore Protection – Dual Slope (WCSP-DS) Zig-Zag Model with Wave Focused Wall

Abstract The Wave Catcher Shore Protection Dual Slope (WCSP-DS) is a coastal structure with dual function of shore protection and wave power generation. WCSP-DS captures seawater through overtopping into the crest reservoir resulting in higher water level than sea. This elevation difference will be pressure height (head) represented by freeboard ( Fb ) together discharge unit q main parameter for electrical power. study aims to increase value at maximum engineering effort transformation process adjusting setting position WCSP zig-zag manner adding wave-focused wall (WFW) produce deformed Hdf front WCSP-DS. Located Hasanuddin University’s Coastal & Environmental Engineering Laboratory, was carried out experimentally using geometrically scaled 1:20 physical model simulations. Three Dimensional (3D) basins size 10 m x 15 1 equipped an automatic generator data recording instrument were utilized. Two type models namely M1 (without collector) M2 (with simulated relative depth d/z ), Fb) , incoming height, period Hi T ). results indicated that increased significantly ranging from 300% 900% on 350% 1100% M2. also increases enters reservoir. By these results, combination can selected which generate optimal
