The new construction of the wading project at the confluence section, where the flow condition is rather complex, has definitely to take more influencing factors in consideration. In order to investigate quantitatively the effect of secondary flows on the transport of flow and sediment in a sharply curved channel, the landscape project at the Yibin reach was taken as an example, and the 2D Mathematical Model was used to simulate the distributions of flow factors. As the predicted project is located at the confluence of the Three Rivers, the left banks of the Minjiang River and the Yangtze River, the complexity of the inflow and outflow conditions was considered during the study, and different research schemes were compared. Result of this research can be valuable reference for similar projects.
