12水科学与工程技术2023年第5期江苏省滨海县翻身河测区降雨径流关系分析司英凡,任中杰(江苏省水文水资源勘测局徐州分局,江苏徐州221000)摘要:为探索翻身河区域水文特征值及变化规律,利用自动监测和巡测数据,沿区域边界选取多个控制断面和代表点布设水文测验断面和观测站点,依据规范进行水位流量关系测验推导出水位差与流量系数的关系,通过实测资料整编成果进行产流计算面平均降水量P、前期影响雨量Pa实测径流深R及运用最小二乘法和Excel规划率定产流参数C、C,由此得出降雨径流关系,并绘制P+P。与R的关系分析图,通过与30年前的数据做比较,得出径流深系统性的偏大,并与近年来的城市化有关。关键词:翻身河测区;降雨径流关系;产流中图分类号:TV121D0I:10.19733/j.cnki.1672-9900.2023.05.04文献标识码:B文章编号:1672-9900(2023)05-0012-04RelationshipofrainfallandrunoffinFanshenRiversurveyareainBinhaiCountyJiangsuProvinceSIYingfan,RENZhongjie(XuzhouHydrologyandWaterResourcesInvestigationBureauofJiangsuProvince,Xuzhou221000,China)Abstract:InordertoexplorethehydrologicalcharacteristicvalueandvariationlawoftheFanshenRiverarea,multiplecontrolsectionsandrepresentativepointsareselectedalongtheregionalboundarytolayhydrologicaltestsectionsandobservationstationsbyusingautomaticmonitoringandpatroldata.Therelationshipbetweenwaterleveldifferenceandflowcoefficientisderivedbytestingtherelationshipbetweenwaterlevelandflowrateaccordingtothespecification.Throughthemeasureddatacompilationresults,theaverageprecipitationP,thepre-impactrainfallPa,themeasuredrunoffdepthR,andtheleastsquaresmethodandExcelplanningareusedtocalibratetherunoffparametersC,andC.Fromthis,therainfall-runoffrelationshipisobtainedandtherelationshipbetweenP+PandRisdrawn.Bycomparingwiththedata30yearsago,itisconcludedthattherunoffdepthissystematicallylarger,andtheanalysiscanberelatedtotheurbanizationinrecentyears.Keywords:Fanshenriver;relationshipofrainfallandrunoff;productionflow降雨径流关系分析是水文计算和水文测报的基础,可找寻流域内径流的形成规律,定量分析流域平均降雨量、径流量、土壤含水量、降雨过程与流量过程间的关系。以江苏省滨海县翻身河测区为例,通过与以往降雨...
