Yangtze River delta is one of the most economically developed and densely populated regions of China, and it is often affected by the storm surge and large waves induced by Typhoons. The terrain in Yangtze Estuary is complex with four branches entering the ocean and many underwater ridges, making the tide-wave interaction complicated. A well understanding of the tide-wave interaction during typhoon processes is important for the disaster prevention and mitigation. In this study, a coupled storm surge and typhoon wave model was setup based on ADCIRC and SWAN model. The computation domain extends from Datong station to the sea outside Yangtze Estuary. The model was verified by simulating the storm surge process during 7 Typhoon processes. After model verification, storm surge and typhoon wave processes during typical typhoon processes that affects Yangtze Estuary were simulated with the model. The characteristic of tide-wave interaction during the typical typhoon processes were analyzed by comparison between the simulated results obtained from the coupled model and uncoupled models. The effects of the terrain on the tide-wave interaction were discussed. A general portray of the tide-wave interaction in Yangtze Estuary during typhoon processes was given.
