Flood disaster is very serious in middle reaches of the Changjiang River. This paper narrated the method of building monitoring-flood system that was based on the RS and GIS. Introducing the system monitoring goals, structure and flow, technique course, and analyzing the system by applying it. Hope that by RS and GIS, high-tech measure can be served for providing decision-making in finding out the situation of flood, designating the resisting-flood scheme, rebuilding after flood for interrelated departments in middle reaches of the Changjiang.
