| Research Abstract |
Tsunami submerged breakwater (TSB) is proposed as a new disaster mitigation hardware reflecting on serious damage by the 2011 Tohoku Tsunami. TSB can change directions of horizontal and vertical tsunami flows, and weaken tsunami power in coastal regions. At the beginning of the research, actual structures aiming for tsunami disaster were investigated about damage condition by the tsunami and weakening effect for the tsunami. Based on the investigation, a geometrical form of TSB was designed from the hydraulic engineering approach. The form was evaluated by the hydraulic experiment and the three-dimensional numerical modeling. And necessary conditions of TSB as a concrete structure to put into practice were examined.
