Numerical Modeling Of Tidal Current And Sediment Movement In Island

With the increasingly developed science and technology,many scholars and experts on the tidal and sediment movement carried out extensive research,and achieved very good results.However,due to the complexity of the movement of the tidal current in the coastal estuarine area,there are still many problems to be solved urgently.Therefore,the study of the sediment transport law under the tidal current in the coastal estuarine area is the key to the protection of the coastal environment,Pollution has a profound and important significance.In this paper,the dynamic law of the sediment in the sea area under the action of wave and tidal current is simulated by means of numerical simulation,theoretical analysis and so on.Simulation and analysis are carried out in the vicinity of the project.Sediment distribution,and provide the basis for the optimization of engineering layout.This paper mainly works in the following aspects:(1)To establish the mathematical model of the tidal current,and to validate the rationality of the mathematical model of the engineering location and its nearby waters using hydrological observation data.(2)Using the verified tidal current model to calculate and analyze the change of flow field near the project sea area after the project implementation.(3)The two-dimensional mathematical model of sediment movement under the wave tidal current is established,and the rationality of the sediment model is verified by the historical map data and the measured topographic data.(4)Using the mathematical model of sediment to calculate and analyze the scouring and silting conditions in different schemes.
