Beach erosion control structures comprising a perforate wall designed to combat erosion of a beach shoreline by wave action. The wall includes multiple courses of cored concrete blocks laid on their side so that the core holes provide horizontal passageways through the wall for the flow of water and entrained sand in incoming waves. The wall also includes multiple rows of such blocks arranged in such manner that the core holes of adjacent rows of blocks are staggered. |
