Study on Bositeng Lake by 2D Hydrodynamic Mathematical Model

the wind field is the main factor impacting the hydrodynamic force in lake. It can change the speed and direction of the water body motion as well as affect the transport and dissipation of subjects in lake. Through the analysis of the wind fields in the large lake area of the Bositeng Lake,variations of wind power and direction are precisely estimated as well as the plan 2D hydrodynamic force model of the Bositeng Lake is established. By application of the model,the hydrodynamic force of the Bositeng Lake is simulated and predicted, impacts on the structure of the lake flow fields by different wind direction and speed is analyzed. These provide the further study of the hydrodynamic force and transport dissipation of pollutant in the Bositeng Lake with theoretical basis.
