Review and outlook on the analysis methods of rainfall warning indicators for flash flood early warning
摘要
Abstract
The early warning thresholds for flash flood disasters serve as the cornerstone of flash flood prediction and early warning systems.Currently,China predominantly relies on empirical methods and water stage-discharge backward extrapolation method to establish rainfall thresholds for early warnings.Additionally,there is a gradual shift towards adopting composite threshold and dynamic critical threshold approaches.In light of a comprehensive assessment of commonly used rainfall threshold analysis methods both in China and abroad,future research should prioritize modifying existing techniques.Specifically,attention should be directed towards accounting for the spatio-temporal variability of rainfall events,high-concentrated sediment flow,debris flow,and other uncertain factors.关键词
