This project is a key project of the Beijing Natural Science Foundation, which is led by Beijing Normal University. Other participating organizations are the National Disaster Reduction Center of the Ministry of Civil Affairs, Beijing Hydrology Center, and Beijing Urban Planning Research Institute. The project leader is Professor Zongxue Xu. According to the particular needs of Beijing City and important scientific topics, such as changes in hydrological cycles, the risk of flood disasters, and water safety, a typical watershed will be selected as the study area for developing and testing a distributed hydrological model. By synthetically simulating measures that are not based on engineering, such as urban drainage pipeline networks, weirs, and flood dispatching schemes, a model of flood evolution in low-lying areas will be developted, coupled with hydrological and hydraulics methods. Moreover, a vulnerability assessment model will be developed based on flood vulnerability and waterlogging disaster systems. This project will entail a comprehensive study of the mechanism of flood disaster, attending to aspects of runoff generation, flood disaster formulation, and the evolution of vulnerability. Accordingly, emergency management measures will be proposed, thereby providing a scientific basis for flood control and disaster reduction in Beijing City.
