宁夏山洪灾害雨量预警值计算
Calculation of early warning value of rainfall for torrential flood disasters in Ningxia
摘要
Abstract
With the implementation of non-engineering measures on flood monitoring and early warning and the nationwide flood disaster prevention construction from 2013 to 2015,the comprehensive ability of the entire Ningxia region in flood control and disaster reduction has significantly improved.But,currently there is no early warning index for scientific,systematic and quantitative analysis of flood disasters such as rainstorm,flood,water logging,landslides,and mudslides,making it difficult to conduct emergency disaster relief,emergency response and emergency rescue in sudden flood disasters.In light of the actual river distribution and flood control project construction in Ningxia,based on the existing methods of ascertaining critical rainfall,we used the rainstorm isoline and P-Ⅲ frequency curve table to estimate the rainfall value corresponding to different flood magnitudes,and used the value as the early warning value for flood disasters.This method is simple and easy to operate.The calculation results have important significance to flood prevention and disaster reduction in Ningxia.关键词
