Outline of Final Research Achievements

Destructive and wide spanning erosions by tsunamis and storm surge often obstruction for rebuild. The reconstruction requires breaking mechanism to build robust structures. This study accounts two measure mechanisms, bottom shear stress and liquefaction, and find robust structures.
