Abstract

  A resonator-like breakwater facility was constructed at the entrance of Port of Long Beach (Pier J) to shelter the harbor basin from comparatively long waves having a period of about one minute or longer. Major purpose of the resonator-like breakwater is to reduce long-period ship motions during cargo handling at the pier. In order to improve the performance of the breakwater facility especially for much longer period waves, say greater than a few minutes, we have already proposed a modified resonator. It has a pair of additional walls connecting to the nearshore side jetties of the previous rectangular resonator. In this study, performance of the modified resonator for protecting the harbor basin from very long waves has been examined as compared to that of the previous rectangular resonator. As an additional examination, influence of the obliquely incident waves to the harbor on the performance was also clarified.
