A method of building up and maintaining beach sediment, building and changing beach profiles, and controlling beach erosion that uses a series of varying diameter plastic pipes joined to obtain various lengths, laid parallel and on top of each other and situated perpendicular or at various angles to the shoreline. The pipes act to slow bottom currents and promote sand accretion in and around the pipes thereby stabilizing shoreline profiles and controlling beach erosion. The pipes are held together by cables or in a “cradle” to help stabilize the pipes on the sea bottom. Certain pipes have pre-drilled holes of various diameters through their sidewalls to allow in-flow of sand-carrying water such that the pipes become filled with sand acting to stabilize the pipes. Pipe diameter sizes are selected as necessary to accomplish most efficient sediment accumulation around the pipe structures.
