Abstract
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.
Claims9
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.degree., 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.
The method for protecting a shoreline against erosion which comprises placing, in side-by-side relation, in the surf zone adjacent said shoreline a plurality of concrete modules having the configuration of a triangular prism, with the long parallelogram face of said prism being placed on the bottom, the seaward face of said prism being at an acute angle to said bottom face so as to present a gentle slope to incoming waves and with the beachward face of said prism being at an angle less than 90.degree. to said bottom face, said modules constituting a reef.
