Abstract

  In this research, the effectiveness of the newly developed resonator against tsunamis has been theoretically examined. We assumed, in this paper, tsunamis as very long waves with the wave period of 20 to 30 minutes. By adopting the typical bay, the wave height distribution in the bay was investigated for the various cases of breakwaters systems such as the harbor with conventional jetty-type tsunami breakwater, harbor with rectangular resonator and harbor with newly developed resonator. By comparing the results, it was realized that the performance of the newly developed resonator is better for protecting the bay area from tsunamis.
