Abstract

Abstract

During the process of typhoon, storm surges and waves are concomitant and interact with each other. Wave-induced radiation stress plays an important role on the nearshore.To get correct radiation stress, storm surge. The traditional 3rd generation sea wave model is time-consuming and can not meet the requirements of operational forecasting. On the basis of primitive expression of wave-induced radiation stress,a simplified radiation stress expression is deduced and can be easily added to the storm surge model. A practical storm surge model including the role of wave set-up in nearshore waters is proposed. The new model can not only improve the physical process of wave set-up and time-saving, but also obtain a more satisfactory result than the old one through two disastrous storm surge's simulation in Guangdong coastal areas.
