An artificial reef which protects the shoreline from erosion is created by placing in the surf zone, in side-by-side relation, reinforced concrete prisms having a gently sloping seaward face provided with parallel, transverse grooves which assist in dissipating wave energy and the release of water-borne sediments while minimizing secondary waves.

A concrete module for a shoreline breakwater adapted for placement in the surf zone comprising a triangular prismatic shape having three major parallelogram faces, a long face to be the foot, a face forming an acute angle with said foot so as to form in use a gently sloping seaward face, and a beachward face forming with said foot an included angle less than 90°, with the sides of said prism being substantially triangular, said seaward face having a plurality of transverse parallel grooves indented therein, whereby wave energy is dissipated as waves run up said seaward face, said grooves being shaped such that sand-like solid material carried up said seaward face by wave action will slide down said seaward face.
