Abstract

A large resonator which has a similar size of the outer basin of a double-basin type harbor is designed by the Wave Filter Theory. This resonator aims to protect an inner basin from incoming very long waves which may cause long-period motions of moored ships at piers. Performance of the designed resonator is examined by the physical and numerical experiments. It was confirmed that the large resonator designed by the Wave Filter Theory is effective for protecting the inner basin from very long waves with a period of 30s or longer. However, the aspect ratio of the resonant basin should be nearly equal to 2:1 for the effective reduction as pointed out by Valembois(1953).
