Hydrodynamics in shallow closed water bodies such as shallow lakes and reservoirs, which is primarily caused by wind shear acting on the water surface, is one of the key issues in the field of water environment. It is relevant to water quality and sustainable management of closed water bodies through influencing the distribution of dissolved substances, nutrients, microorganisms and plankton. However, the circulation can be influenced by the excessive growth of floating aquatic plants in summer, which may make water quality of closed water bodies become worse. Therefore, knowledge of water movements in closed water bodies in response to winds blowing over the water surface is great of significance in examining and maintaining their water quality in good condition. Aiming at that objective, this research has been done to build a two-dimensional, unsteady, laterally averaged model for simulating the wind-induced hydrodynamics in closed water bodies. This paper will present primary results regarding to development of a two-dimensional numerical model for simulating the wind-induced flow in closed water bodies. On the basis of this research, the model can be extended to simulate water quality in these water bodies.
