The structure includes a base frame (20) adapted to rest on the bottom of the body of water, a ballast supporting member (38) secured on the base frame in order to receive ballast such as rocks to help anchor the structure in position. A barrier plate (40) is secured to the seaward portion of the base frame and is angularly disposed to slope upwardly and toward the shoreline and to extend above the mean water level to present a sloping surface to onshore waves.</p> |
