Abstract: the sediment variation in the Baogang dock frontal channel from 1994 to 2002 was simulated using DEM (Digital Elevation Model) and GIS (Geography Information System). The results were as fol-lowing: the Baogang dock channel was general character of erosional from 1994 to 2002, and the total erosion quantity is 113.563×106m3; the average rate of erosion was 14.195×106m3/a;From 1994 to 1999, the channel was erosional, and the total erosion quantity was 53.286×106m3; 1999 to 2002,Baogang dock channel was also erosional, and the total erosion quantity was 60.277×106m3. Sediment was distributing in the upside area about Shangduan Sand and the area between the Shangduan Sand and the New Liuhe Sand. The channel change was a result of the channel borderline conditions, water discharge, suspended sediment load and human activities. The continual movement of the Shanduan Sand to southeast exert potential pre-ssure on the development of Baogang dock.
