Three-dimensional numerical modeling for winddriven circulation and pollutant transport in a large-scale lake
(0) A three-dimensional numerical model for wind-driven and pollutant transport has been developed which is comprehensive (containing the appropriate physics) and generalized (requiring minimal tuning) and adaptable to various applications of lake environment with complex bathymetry. A concentration-correction method is introduced in the paper which is simple and efficient to keep conservancy for scalar transport where large water level variation exists in the winddriven circulation lake. Nonlinear advection scheme is used with flux limiter in the paper which can increase the accuracy and decrease the nonphysical oscillation for scalar transport. The model was tested against analytical solutions for source diffusion and Minmod was chosen as the most fit flux limiter applied to Taihu Lake, the third largest freshwater lake in China. The simulated result shows that the model can simulate the pollutant transport by wind-induced circulation correctly.
