LATERAL VERSUS LONGITUDINAL ARTIFICIAL REEF SYSTEMS

Yoshimi Goda, Hiroshi Takagi

Abstract


A new submerged breakwater structure for shore protection is proposed and called the longitudinal reef system. It is efficient in dissipating wave energy by increasing wave heights at the front through wave refraction effect and by enhancing wave breaking. Comparison is made between the new longitudinal reef system and the conventional broad-crested reef system through model experiments and numerical computation. The superiority of the longitudinal system to the conventional system is confirmed through the comparison.
