Abstract-This paper proposed a hydrodynamic model for the The hydrodynamic module of EFDC mainly uses the
Meiliang lake based on the Environmental Fluid Dynamical principle of CH3D’ hydraulic model, on the basis of the two
Code (EFDC). Considered the different speed of wind and the bands limited differential, which may get the numerical
process of reservoirs operation, we have been analyzed the solution in vertical, free surface and disturbance, and then may

when the wind speed is 3m/s, the velocity of water flow is [2].
