Abstract
Three-dimensional non-hydrostatic computations by means of MITgcm were conducted to simulate the thermal structure and its evolution in the dam lake. Meteorological forcing such as the wind stress, atmospheric pressure at surface and heat flux transfer through the lake surface and the river inflow are the major causes of water circulation in the lake, that were computed by the meso-scale meteorological model MM5. An important vertical mixing and sub-grid scale motions were calculated by the Smagorinsky's nonlinear viscosity model. One month computation of physical water quality in the dam lake revealed that both the computed wind-induced currents and the thermal structure show good agreement with observations.
