A Study on the Water Flow in Baiyangdian Lake
白洋淀内水体的流动特征研究

A study on the influence of wind stress on the flow character of water in Baiyangdian Lake is carried out, and we arrive at some important conclusions. These are: (1) wind stress can be regarded as the main driving force of the water circulation flow; (2) the water flow direction of surface layer is the same direction as the wind moves, while direction of the layers below is on the contrary or is almost inversed; (3) the flow character of water beneath the surface layer is complex. Double eddies can be seen evidently on the second horizontal layer; (4) the topography influences the vertical flow heavily, double eddies can also be seen in the complex vertical direction. The dynamic character of water in Baiyangdian Lake is studied in this paper, which laid a solid foundation for the further researches on biology.
