Key Challenges and Solutions in Flash Flood Disaster Prevention in Qinghai Province
In recent years,under the background of warming and wetting on the Qinghai-Xizangi Plateau,Qinghai Province has experienced frequent occurrences of extreme strong convective weather.The characteristics of flash floods,such as suddenness and locality,have become more pronounced,posing a severe threat to the safety of people's lives and property.Based on an investigation of the routine flood prevention and control work in grassroots departments,a systematic review revealed several key challenges,including heavy flood defense tasks at the grassroots level,weak technical capabilities,insufficient monitoring station network density,and a significant mismatch between flood channel management and actual needs.In light of these findings,and in combination with practical work experience,several countermeasures are proposed,include conducting flash flood hazard investigations and impact analyses,enhancing rain and water monitoring capabilities,constructing and applying rainfall radar systems,developing digital twins for small watershed flash floods,increasing efforts in flood channel management,and advancing scientific research.These recommendations are of great practical significance for the prevention and management of flash flood disasters in Qinghai Province.
