摘要
根据山洪灾害调查评价前期成果,利用点面雨量换算系数计算沿河村落点雨量预警指标,采用单站就近原则法,将沿河村落的点雨量预警指标直接关联到指定的自动雨量站,经分析计算,典型沿河村落预警指标与雨量站关联成果基本合理,以期由雨量站直接对沿河村落进行雨量预警,为实现山洪预警信息迅速精准靶向发布,提供基础数据。
According to the previous results of the mountain flood disaster investigation and evaluation,the point-to-surface rainfall conversion coefficient is used to calculate the rainfall warning indicator of the riverside village,and the single-station distance nearest law is used to directly link the rainfall warning indicator along the river village to the designated automatic rainfall station and carry out a rationality analysis,in order that rainfall monitoring will be carried out directly from the riverside villages by the rainfall station,which provides basic data for the rapid and accurate targeted release of the flash flood warning information.After analysis and calculation,the typical results of the early warning indicators along the river village and the rainfall station are basically reasonable.
