The evolution of erosion and deposition in sea area is the key factor affecting the safe operation of power plant water intake-outlet.Based on the laws of water and sediment movement and geomorphic evolution in the sea area,a two-dimensional tidal and sediment mathematical model is used to calculate and analyze the changes of hydrodynamic conditions and the evolution law of erosion and deposition in the sea area,where the water intake-outlet of a coastal power plant and wharf is located.The research results show that:after the construction of the project,the velocity of the waters on the north and south sides of the wharf decreases,while the velocity on the southwest area near the main channel of the tidal waterway increases.Under the influence of velocity change,the sea area on the north and south sides of the wharf is enhanced,and the sea area in the southwest of the wharf is mainly scour.The water intake is located in the wharf basin,and the range of erosion and deposition after the project is 0.026 m/a,which has a limited impact on the water intake.The research results can provide theoretical basis and technical support for the layout of wharf and water intake scheme.
