城市雨-洪-涝复合灾害成因及防控关键理论方法研究思路OA

Along with climate change and rapid urbanization,recent urban rainstorm flood events have been presented as compound disasters characterized by rainfall-flood-urban inundation coupling,featuring rapid risk transmission,difficult forecasting,severe disaster situations,and a lack of defense standards.This study identified key scientific issues that need to be addressed in the study of urban rainstorm-flood compound disasters,including coupled integrated forecasting and rapid early warning methods based on the formation mechanism of urban rainstorm-flood compound disasters,the combination probability of urban rainstorm floods encountering each other,the return period and defense standard of compound disasters,the principle of risk transmission superposition,and the rapid diagnosis and suppression mechanism of urban rainstorm-flood compound disasters.Research content and technical routes oriented towards scientific problems were proposed.It is believed that solving the challenges of early warning for urban rainstorm-flood compound disasters,rapid risk diagnosis,and rapid suppression responses are crucial for the prevention and control of urban compound water disasters.
