Brief Discussion on the Design of Decision Support System for Flood Control Operation in Yangtze River

Flood control operation is the top priority for the management of the Yangtze River. To improve the timeliness and reliability of operation decision, it is of great significance to establish a set of intelligent decision system for flood control management, which can serve multi-level users. In order to achieve the goal, the key is to modularize the core business functions through the construction of topology relations of river network and control sites for the Yangtze River. In this paper, it would integrate the functions of hydrological forecast, flood propagation, flood control operation and flood risk analysis for the core business. Based on the core business model and information expansion interface, we develop flood control decision support system of the Yangtze River by virtue of GIS visualization and interactive WebService technology. The system can realize the real-time query of water-rainfall information and the fast-time simulation of flood control scheduling scheme, so as to provide the professional, scientific and accurate technical support for the group decision in the flood control.
