Abstract:

Based on topographic summary of estuaries and taken into account of many factors including river discharge, tide, channel topography and mixing type between saline water and fresh water, a fast prediction model for daily maximum chlorinity and maximum distance of saline water intrusion was set up and used to simulate and predict the saline water intrusion in the West River Delta. The results show that the model can be used to simulate daily maximum chlorinity and maximum distance of saline water intrusion in the channels in the West River Delta. In addition, the model can predict the degree of effects of topographic variation and other environmental factors such as river discharge and tide on the saline water intrusion. More actual data or parameterizations are needed to further quantify other factors to amend the model, hence to improve the accuracy and prediction of the model.
