Research of Extraordinary Floods Disaster Scenario Construction and Simulation-Taking Yongding River as an Example

The Yongding River flood disasters frequently occur, which has great harm to the safe operation of Beijing city. Through the study of the catastrophic floods of Yongding river scenario construction, it demonstrates in the development of Yongding river catastrophic floods. Disaster simulation was carried out by MIKE RR model, the emergency response capacity gap was analyzed according to the simulation results, and the countermeasures and working mechanism of the flood disaster in Yongding River Basin were improved. Disaster simulation of MIKE RR model provides data basis for disaster prevention and response work, and on the basis of perfecting flood control and emergency response plan, in order to prevent catastrophic floods emergencies to provide strong support and technical support.
