Experimental Study of Wave Run-Up for Porous Concrete on Seawall Structures

Abstract

A seawall is a coastal barrier that prevents waves from reaching the shore. The approach of waves increases the height of coastal structures. Coastal protection structures must manage wave run-up to prevent erosion and abrasion adequately. Experiments were conducted to measure wave runup by adjusting the angle of the Seawall and implementing porous concrete armour units. The wave run-up is directly proportional to the slope angle of the structure. The most steeply sloped section with a ratio of 1:1 (0.150 m) produced the highest run-up, followed by a slope ratio of 1:1.5 (0.132 m) and the least steep slope ratio of 1:2 (0.128 m).
