Recent years, there were many piers constructed in tail reach of Yongjiang River. This made river channel in estuarial reach shrank gradually, which in turn influenced the shipping ability of estuarial area. Taking Qingshuipu pier that would be constructed in the left bank of Yongjiang river estuarial reach as an example, a numerical simulation have been done, and resistance parameter had been proved reasonably by author. The flow pattern, backwater height and channel scour-fill intensity near the pier trestle have been studied in different kinds of flood and tidal stencils. In engineering project, the trestle prevents flood from diffusing by dipping into the river. Meanwhile, backwater and deposition occur in the bank, which have impact on flow capacity. If the siltation in the area accumulates, then, point bar could not be scoured adequately in great flood period, which will force mainstream to move towards right bank. Based on the backwater and local scouring and silting situation near the pier trestle, the author puts forward a revised proposal and gains a preferable result. So, reasonable pier arrangement is the important condition for keeping steady and healthy to the tail reach of tidal river.
