Outline of Final Research Achievements

We have successfully developed a new fuselage breakwater "biplane" to dissipate drastically both height and energy of Tsunami waves not by damming water but reflecting waves tactically. This paper presents the concept of fluid mechanical design with respect to the new fuselage breakwater "biplane" and its feature of wave reflection mechanism. In this research, we report a wave-absorbing property of the proposed breakwater and its efficiency by conducting verification of both tank and numerical experiments. Our knowledge and the theory obtained from this research are rich in novelty and very useful for the future coastal engineering and tsunami prevention.
