| Abstract: | The main dynamic factors affecting the Changjiang River mouth saltwater intrusion are upstream runoff and outsea tide. In this paper, the observed salinity data are used to verify the two-dimensional mathematical salinity model, it is shown from the simulated results that the simulated results are consistent with the observed data, and the simulation computations for 4 kinds of hydrographic condition combination are made based on the above-mentioned mathematical model. Finally, the basic regularities of the horizontal distributions of the Changjiang River mouth saltwater intrusion are obtained by analyzing the computed results. |
