Abstract

 It is becoming important to consider the growth of wind waves due to strong typhoon winds in the bay. However, wave growth in the bay is an intermediate phenomenon hardly modeled by either spectral wave model or phase resolving wave model. Therefore, it is necessary to introduce wind stress terms in the phase resolving wave model that doesn’t usually deal with wind wave for inner bays. In this study, we implemented the wave growth term into the phase resolving wave model by considering wave scale momentum exchange between wind and wave interactions. A spectral wave model was used to optimize the parameterization of wave growth in the wave resolving model. The obtained model was then applied to the case of Kansai Airport inundation by the extreme waves of Typhoon Jebi in 2018 to estimate the overtopping volume. Besides, we compared it with the measured values.
