Shore erosion prevention modules

摘要

A series of modules for initiating the creation of a sandbar to halt the erosion of a beach along a body of water. Each module has a heavy concrete base, formed in a ring with a central vertical aperture, which is placed beneath the water near the shore. A series of boards which extend parallel to the shore line are maintained one above the other by a pair of attached flexible belts each of which is also attached to the base at either end. The boards, bound by the belts, form a web which is permitted to drop downwardly during water flow toward the shore line. During water flow from the shore line, the web of spaced boards rises upwardly to form a pocket which is held in a slightly curved position by the belts. The apertured board arrangement retards the water flow sufficiently to cause the deposit of sand onto and adjacent to the base of the module. When arrayed in a row, generally paralleling the shore line, the modules serve in time to create a sandbar and eventually become fully buried.
