Abstract：Three-dimensional wave-current coupling numerical model was established based on the FV-COM(Finite-Volume Community Ocean Model)circulation model and wave model.Numerical simula-tion on the hydrodynamic environment characteristics of Zhoushan island sea area was performed.The tidal current and wave characteristics of Zhoushan island sea area were mainly investigated.The results showed that the reciprocating current was dominate in the nearshore area and the rotating current was dominant in the offshore area of Zhoushan islands.The ebb tide was stronger than the flood tide in most areas of the Zhoushan islands.The vertical current velocity in the bottom layer was about 59％～70％of that in the surface layer.The significant wave height during the spring tide was higher than that during the neap tide,and the significant wave height gradually decreased from the offshore to near-shore area.The effect of wave on the tidal current velocity was related to the water depth,where the current velocity in the nearshore area at small water depth was mostly affected by waves.
