Wave Transmission and Energy Dissipation in a Box Culvert-Type Slotted Breakwater

This research is conducted to examine the transmission wave and energy dissipation of a box culvert-type slotted breakwater, which designed as breakwater structure with watertight wall at top culvert type hole bottom. The process involves physical modeling this in laboratory. parameters are varied determine performance. results show that coefficient (KT) value reduced relative height (hL/d) decreasing length (B/L) steepness (H/L) values increasing. (KD) increases an increment hL/d, H/L, B/L but starts decrease after reaching maximum, optimum H × B/L2 value. found be 0.0034(hL/d)2.618 depending on value, while maximum KD recorded 0.70.
