Simulation of Concentration Distribution due to Waste-Water Discharging into the Deep Water Area in Qiantangjiang River

The flow field is simulated by using 2-D vertical unsteady fluid dynamic equations,in which a κ-ε urbulent model is employed.Based on the flow field,concentration distribution is computed by solving a quasi-3-D concentration equation in the near area of 6-point waste-water discharged in the deep water in Qiantangjiang river.Compared of the surveyed fields,the computational results are reasonable.
