Open publisher page 8 citations

Abstract

A 3-D Hydrodynamic model is used for computing and analyzing the tidal currents for the Yangtze River Estuary in this paper. On the basis of tidal currents analysis, the elementary dynamic mechanisms of salt water flowing backwards form the south branch to the north are discussed. It combines curvilinear orthogonal coordinates in the horizontal direction with Sigma mapping in the vertical direction to calculate and analyze the water level and tidal currents. It shows that the results of calculation are in good agreement with the results of the field data. The model can be used in large estuarine engineering projects such as the Yangtze River Estuary.
