　　Abstract：In order to more effectively guide flood control during the construction period of navigation and hydropower junctions, an intelligent flood control system based on GIS is developed with the existing flood control measures and schemes. The system is developed in view of the problems such as the early warning information is not intuitive, the flood evolution is not visible, and the risk analysis is incomplete. Through database development, flood evolution model, user-defined analysis of flood evolution, and GIS visualization , the system can realize the map display of regional hydrological data, real-time access of flow forecast at the junctions, visualization of flood evolution process, integrated analysis of flood control of the junctions and timely release of early warning information. The use of the intelligent flood control system has improved the capacity of flood forecast and early warning. The capability of flood analysis and disaster assessment is strengthened, which can enhance the decision-making based on flood situation. The safety of the junctions can be effectively guaranteed during the construction period.
