摘　　要：岸滩稳定性及取排水口的水深状况是电厂水工建筑物布置决策的重要依据 ,本文通过遥感和地理信息系统软件的支持 ,在数字化地形图分层叠加的基础上 ,对外高桥码头区的淤积及发展趋势进行定量分析。The stability of coast and the water depth near infall and outfall are important in the decision making for hydraulic structure arrangement. With layered compound method of digitized topographic maps and the support of RS and GIS software, the deposition and evolution of dockfront are analyzed quantitatively. The results suggest that the digitalization of topography is an effective way to study the evolution problems of riverbed and coastal areas.
