The research status of flash flood warning in China

摘要：

　　The article discusses from the disaster mechanism of flash flood to the current situation of early warning system.The formation of flash flood is closely related to rainfall intensity,underlying surface conditions and antecedent soil moisture content,and analysis of the physical process of flash flood disasters is crucial for the study of flash flood warning.Flash flood disaster warning indexes are mainly divided into two types: rainfall warning index and water level warning index.Data-driven statistical induction method and hydro-hydraulic methods based on physical mechanisms are used to determine rainfall warning index; The water level warning index can be directly determined by the upstream and downstream corresponding water level method or by the disaster water level.And summed up the current situation and development trend of Chinas flash flood warning research.
