Study on the Influence of Wind Field on Flow Field and Water Quality of Shijiu Lake
In order to study the influence of wind field on the flow field and water quality of Shijiu Lake,a two-dimensional hydrodynamic-water quality model was constructed based on MIKE21,and the one-dimensional steady-state model was used to provide water quality boundary conditions to simulate the characteristics of the flow field and the transport and diffusion law of pollutants in Shijiu Lake under different wind conditions.The results show that Shijiu Lake is sensitive to changes in the wind field,and different wind conditions will produce aeolian circulation in Shijiu Lake with different shapes and sizes,and the wind field will also affect the distribution of flow velocity.Wind direction is an important factor affecting the transport and diffusion of pollutants in Shijiu Lake,and when the wind direction is southeasterly,the degree of pollutant transport and diffusion in Shijiu Lake is the highest,and when the wind direction is easterly,the degree of pollutant transport and diffusion is the lowest.When the wind direction is constant,the wind speed will also affect the degree of pollutant transport and diffusion.
