Two Dimensional Hydrodynamic and Pollutant Transport Modeling of Jiangyin-Xuliujing Reach of Yangtze Estuary

A 2-dimensional hydrodynamic model (RMA2 model) was applied to simulate currents and potential pollutant transport in Jiangyin-Xuliujing reach of Yangtze estuary. The result was compared and validated with a validated 3D model (Delft3D Model). The results indicate that the RMA2 model can achieve the requirements of reproducing and predicting the tidal flow and water levels. Based on RMA2 model simulations, a pollutant transport model (RMA4 model) was established to simulate the transport process of potential pollutant discharge from a sewage treatment plant for risk analysis. This linked hydrodynamic and pollutant transport model can provide the valuable scientific supports for future study of water quality in the Yangtze estuary.
