Abstract： Based on the theory of 2-D variable zone storm surge equations and the wave action balance equation, a acoupling model combining 2-D variable zone storm surge with the SWAN wave computing model was established, and the effect of the wave-induced radiation stress on 2-D variable zone storm surge for Bohai Bay was studied. Through the simulation of two variable zone storms in this region, the storm surge current field and current process considering and not considering wave-induced radiation stress were obtained and compared with the observation from Tanggu Tide Station. The results show that in relation to the distribution of wind field, the degree of influence for different storm surge was different.The tide process from the coupling model was in good agreement with the observation, considering waveinduced radiation stress and combining  2-D variable zone storm surge with the SWAN wave computing model. The waveinduced radiation stress has a certain effect on the current field near the shoreline.
