Abstract: Based on the test results of physical model for Jinshanzui harbor reach, through the changes of flow pattern within the harbor reach of each planning scheme, computative formulas for siltation suitable to each planning scheme were discussed, the silting intensity, amount of silting and distribution of siltation were computed also. The results expressed that from the point of view of silt accumulation, it is feasible to build harbor at Jinshazui region.
