CONTROL OF WAVE PROPAGATION ANGLE BY TAPERED-SUBMERGED BREAKWATER

Satoshi Takewaka, Isao Irie

Abstract


A new type of submerged breakwater with a triangular plane form which modifies the wave propagation angle is proposed. Its performance is demonstrated and assessed analytically. Preliminary movable bed experiments were conducted. The breakwater was installed in front of the beach to modify the wave propagation angle in the offshore zone. Longshore current and littoral drift were driven through the effect of wave angle modification.
