Abstract
A concrete module for at least partial submergence in the surf to dissipate the energy of wave action and to promote the deposition of beach-restoring sand and pebbles comprises a series of passages which converge toward the shore-facing side of the module and terminate in an upwardly-directed opening which deflects the incoming water flow upward to further dissipate the wave energy and to create a reaction force on the module which tends to rotate or tilt it toward the shore. This tendency aids in neutralizing the natural tendency of barriers to rotate toward the sea as a result of sand being scoured out from beneath the seaward side of the barrier as a result of downwardly-deflected incoming wave energy.
