This paper reviewed the developments in 2-D numerical model of the water flow. By means of the latest observation data of the prototype, the detailed analysis was made on the major thalweg, section, island and bottomland, the erosion and deposition of the river bed and the scour hole near the dock and the law of the fluvial process was obtained. Based on the related references, the evolution trend of the channel after the Three Gorges was finished was predicted. The 2-D mathematical model of the water flow was set up and validated using the latest data. With the model, the flow and velocity of several cases were calculated. The stability computation of the bank at the typical section under difference conditions was carried out by adopting the world widely used Geo-Slope slope stability analysis program. Finally, the synthetical evaluation on the influence of the project on the flood level, velocity, river circumstances, bank protection and flood prevention was made and the conclusion that the construction of the dock had little effect on the flood discharge was obtained.

The degree of water temperature lag during water discharge from the Three-Gorges Reservoir was calculated by use of the thermal equilibrium equation of the reservoir,and the influences of water temperature variation in the reservoir on the procreation of Chinese sturgeons were studied.
