Abstract: A high energy return seawall system which may be assembled on site comprising separate modular units placed along the shoreline for preventing erosion due to severe wave action by dissipating wave energy. Each modular unit includes a plurality of stair steps mounted upon an underlying support structure. A curved baffle is attached to the upper end of the stair steps and has a splash panel extending outwardly from the upper reaches thereof. The seawall system is dimensionally adequate to withstand hurricane force winds, waves and currents and designed to insure the maximum strength for absorbing and dissipating the force of a high energy wave.
