Abstract: The quantity of wave hazards caused by typhoons passing through bays is increasing. To mitigate disasters, an accurate deformation evaluation of typhoon-induced high waves in coastal regions is critical. Severe wind-wave deformation is a phenomenon rarely modeled by current wave models such as the phase-resolving wave model and the spectral wave model. We have added the effect of wave generation by wind to the phase-resolving wave model. In addition, the momentum relation between wind-induced wave development and the mean sea level rise by wind has been introduced to this model, enabling the simultaneous evaluation of high waves and storm surges due to strong wind. The proposed model could successfully calculate the wind-wave development and wave deformation simultaneously. The computed wave development showed an agreement in wave growth rate obtained from the observation data. The suggested model provides overtopping volumes which closely correspond to the estimated values under the calculation conditions of Typhoon Jebi in 2018. [ABSTRACT FROM AUTHOR]
