Abstract

 In the water-front area facing to Tokyo Bay in Yokohama city, the inundation disaster was occured while the typhoon Faxai passed in 2019. It was reported that multi-peaked wave overtopping on revetments was occurred while swells invating from outside of the bay was superposed on double-peaked wind waves generated in inside. In this study, the multi-peaked wave and the single-peaked wave are generated to reproduce the inundation in the water-front area by using a Boussinesq wave model, respectively. Small differences are found out in comparison between both calculation results while they slightly underestimate the trace levels observed by field survey. Therefore, it suggests that more suitable estimation of invating swell energy in the multi-peaked wave spectrum is important to reproduce the inundation with better accuracy.
