ABSTRACT:
The subject invention is directed to a beach-front ecosystem erosion prevention system which can be comprised of the combination of a sand ladder located at a sand dune of the beach-front ecosystem and a sand ladder reef submerged in the water of the beach-front ecosystem. The sand ladder has a curved surface facing the water, while the sand ladder reef has at least one such curved surface facing the shore-line of the beach-front ecosystem. Each of the curved surfaces of the sand ladder and/or sand ladder reef is comprised of a plurality of individual plank members arranged in an overlapping, non-touching manner so that openings between the plank members are created. The curved surfaces of the sand ladder and sand ladder reef are concave in shape and act to work with the force of the approaching wave, or retreating undertow wave. The open spaced (slotted) configuration of the plank members allows sand which is carried within the wave and/or undertow wave, to be deposited within the openings between the plank members. This sand retention and holding system maintains the sand ladder and/or sand ladder reef securely in their positions, while also performing the ultimate required task of the system of retaining sand at the sand dune and/or in the surf area between the shore-line and the main body of the water.
