Numerical Simulation of Soliton Fission in 2011 Tohoku Tsunami using Nonlinear Dispersive Wave Model

Abstract

By the image taken from the helicopter, it was confirmed that the soliton fission caused the second wave to be the wave group, in 2011 Tohoku Tsunami. There is a possibility that amplification of wave height caused by soliton fission had expanded damage. In this study, we developed the nonlinear dispersive wave model which can be practicable to reproduce the soliton fission wave. And, the applicability of the developed model was verified by simulating the reproduction of the soliton fission in 2011 Tohoku Tsunami.
