Abstract: Discharging a flood of 158 000 km2 from the upper and middle reaches of Huaihe River, Hongze Lake is mainly surrounded by plain and depression which are subject to flood disasters. In the aim of reducing regional flood risk and alleviate flood losses, a B/S-structured management information system of dynamic flood is developed based on WebGIS by constructing flood routing models for three types of risk source including external river flood, regional flood and rainstorm waterlogging. On this basis, the dynamic flood risk map is generated by using dynamic layer. With this system, the rainfall and water information, static and dynamic flood risk information, as well as disaster loss information under planning and simulated conditions can be managed comprehensively, and the 2-D flood routing process can be displayed dynamically, which is conducive to strengthening regional flood control and establishing evacuation schemes.

Key words: Hongze Lake, flood routing model, WebGIS, dynamic layer, management information system (MIS)
