Beach replenishment system

Year	Description
1997	Invention patented by George M. Beaver on March 2nd, 1997. Abstract: A beach replenishment system comprising a plurality of barriers mutually separated by troughs. Each barrier comprises two arms mutually attached at a barrier arm angle. The intersection of the arms defines a barrier vertex. An extreme of each arm opposite the barrier vertex terminates in a barrier arm end wall. Each arm comprises a descending series of parallel terraces. Each terrace comprises a shoulder and a valley, or, in an alternate embodiment, a land separated from a shoulder by a valley. The lowermost shoulder borders a ramp which is substantially parallel to a surface upon which the barrier rests, whereby receding water is projected away from the barrier and erosion under the barrier is thus minimized. Each arm is supported by vertical and horizontal braces. Runout posts are installed opposite the troughs, and barrier posts are installed opposite each barrier. Areas between adjacent barriers may be dammed and receding water channeled through a pipe to a turbine turning a generator, which may be used to generate electricity. An alternate embodiment, a seawall, comprises a wall rigidly attached to a single terrace at a right angle. The terrace comprises a valley adjacent the wall, and a shoulder. The shoulder is bordered by a ramp, which is substantially parallel to a surface upon which the seawall rests.
