ABSTRACT:
In a breakwater which comprises a back wall, and at least one front wall pierced with holes to break up the impact of an incident wave, the improvements are proposed of providing a sloping back wall; of providing convex-concave indentations on the back wall; and of providing partitions to divide up the space between the back wall and the front wall or walls. Various embodiments include an embodiment with two front walls in which the holes in the rearmost front wall are smaller than the holes in the foremost front wall.
