| Research Abstract |
In order to prevent or minimize the tsunami disaster in a ria bay, typically Sanriku Dsitrict, effective layout of tsunami breakwaters at the mouth of ria bay has been extensively studied. The concept of a water wave resonator for reducing incoming tsunamis is introduced. The new type of wave resonator has also been adopted to reduce tsunami heights at the inner coast of a ria bay as compared to the effectiveness of a traditional tsunami breakwater.
