Gong Lake Xidong Water Works Water Quality Study

On the basis of analysing the Gong lake water resource and environmental current situation, through build the wind catch flowing water dynamics model and the water quality model of Tai lake, calculate density field change of Gong lake in different environmental condition , analyse the influence of pollution from rivers and Tai lake to Gong lake. With the pollution from WangYu river ,Daxi river,Xiao river increase , the water quality of Gong lake become worse. At blowing SE wind , The Wangyu river blowdown influences water works' water quality obviously, at blowing NW wind ,pollutant of Daxi river,Xiao rive there is obvious influence to water works' water quality.
