Abstract
Wave deformation with fission of solitons and wave breaking of the dispersive tsunami was observed in the 2011 off the Pacific coast of Tohoku earthquake tsunami hitting Kuji Port. Estimation of impacts of such a deformed tsunami is necessary for estimation of damage induced by tsunamis, especially the maximum considered tsunami. A wave breaking model is incorporated in the mathematical model of STOC that is a hybrid model of a hydrostatic model (STOC-ML) and non-hydrostatic model (STOC-IC) for calculation of tsunami propagation and inundation. It is confirmed that the improved STOC-IC with the wave breaking model can estimate the tsunami with fission of solitons and wave breaking in comparison with physical model tests in a wave flume and the observed tsunami in Kuji Port.
