A wave trapping artificial reef (WATAR) has been developed as an efficient wave barrier for a shore protection system. WATAR is a submerged concrete structure placed on a rubble mound. The concrete structure is perforated in such a way as to trap and break incident waves on the structure and cause effective wave energy dissipation and return flow in the structure. Irregular wave experiments were conducted in a wave flume to evaluate the effectiveness of WATAR, typical submerged breakwater and multi-row submerged breakwater in reducing wave transmission, wave set-up and reflection. The crossshore variations of the measured wave heights are indeed encouraging.
