The paper tries to find a better method to solve the problem of analyzing riverbed evolution using geographic information system, and builds a riverbed evolution analysis system based on ArcGIS.

Combining the application of GIS in the domain of sea-route management and using consid-erably ripe technology,the design and implementation of watercourse evolvement and analysis system based on GIS is introduced in this paper.
