In order to accurately simulate the coupled distribution of wave, tidal current and wave-current in muddy sea area under extreme typhoon weather, the advanced Weather Research and Forecasting field model was used to simulate the 10-meter wind speed on the sea surface as the driving wind field of the wave and tidal current. Considering the effect of storm surge, the formation, propagation and attenuation of wind waves in Lianyungang sea area during Typhoon Weipa and Dawei were simulated and reappeared. This paper adopts the three-dimensional tidal current model, considering the factors such as wave-induced nearshore current and the influence of wave on tidal current. There was the anticlockwise circulation circle near the typhoon center, but it was not obvious under the action of gale wind. Due to the sudden change of surface wind and barometric pressure in the sea area, the sea level and the tidal level rose strongly, and the influence of nearshore windblown current was very obvious. The wind-wave-current coupled model could better reflect the hydrodynamic field during typhoon, the changing process of which can provide dynamic conditions for further simulation of river bed erosion and siltation during typhoon.
