ABSTRACT
ABSTRACT: The Tianwan nuclear power plant is located at the Gaogong Island, south of Lianyungang Port in China. The ocean area near the Tianwan nuclear power plant is frequently struck by typhoon and strong wind of the cold wave. The sediment concentration near the bottom will become larger under the strong wind weather. In the paper, the three-dimensional model for the tidal current and sediment transport is used to predict the maximum sediment concentration and deposition depth in intake open channel. The results show that sediment concentration is high in outer segments and low in the breakwater; the maximum vertically averaged sediment concentration near the head of the breakwater and at front end is respectively about 1.27 kg/m3 and 0.745 kg/m3; under the action of “Wipha” typhoon, maximum deposition depth in the intake open channel is 0.11 m. So after the implementation of the project, it didn’t emerge obvious sudden deposition.
