摘要
【目的】为了在监测资料缺乏地区划分内涝灾害风险等级,开展内涝风险预警,借鉴山洪临界雨量相关计算方法推求隐患点临界雨量。【方法】以满洲里为例,联合采用单站临界雨量法和反距离加权法对现有气象站网雨量监测资料、内涝过程积水深度、小时降雨量、内涝隐患点地理信息等资料,进行分析计算。【结果】得出互贸区、基准站等7个自动雨量站,4个内涝预警等级下17个单站临界雨量值在2.5~39.6 mm之间。华埠大街套娃广场门前等23个内涝隐患点,4个内涝预警等级下92个致灾临界雨量值在4.30~29.11 mm之间。【结论】根据计算得出的隐患点致灾临界雨量,开展内涝灾害风险等级预警服务,取得了良好的效果。
In order to classify the risk level of waterlogging disaster in areas with insufficient monitoring data and enhance the early warning system of waterlogging risk,this study obtained critical rainfall values in the danger-hidden points by drawing on critical rainfall calculation model of mountain torrents.Taking Manzhouli as an example,we adopted a combination of single station critical rainfall method and inverse distance weighting method to calculate and analyze the existing rainfall monitoring data from meteorological station networks,waterlogging depth during the rainfall process,hourly rainfall,and geographical information of waterlogging danger-hidden points.Our findings assert that the critical disaster-causing rainfall values for 17 single stations under the four waterlogging warning levels are between 2.5 and 39.6 mm at seven automatic rainfall stations,including the Mutual Trade zone and the base station.At the 23 danger-hidden points in front of the Taowa Square on the Huabu Street,there are 92 critical rainfall values under the four waterlogging warning levels,varying from 4.30 to 29.11 mm.Applying these critical rainfall values to waterlogging risk warning has achieved good effects.
