WebA breakwater structure is designed to absorb the energy of the waves that hit it, either by using mass (e.g. with caissons), or by using a revetment slope (e.g. with rock or concrete armour units). In coastal engineering, a revetment is a land-backed structure whilst a breakwater is a sea-backed structure (i.e. water on both sides). WebIn the early stage, analytical solutions are the most widely used method to study the wave induced soil response around submerged permeable breakwater (Jeng, 1996), in which the breakwaters are simplified as lines without width and weight. Later, numerous numerical models are developed to study the wave-breakwater-seabed interactions.
