Numerical simulation of transport and dispersion of side-discharged sewage in tidal flow

Based on N-S equations, the depth-averaged stress-flux algebraic model is used to simulate the anisotropic transport and dispersion when hot water or pollutants are side-discharged into large water body. In this model the depth-averaged continuity, momentum and concentration equations are employed, and the tide is asymmetric. The results show the changes of velocity field and pollutant con centration with time and space during one tidal period.
