Abstract
On July 21, 2012, heavy rainstorm hit the water system of the northern branch of Daqinghe River in Haihe River Basin. Floods oc-curred at the Jumahe River in the northern branch of DaqingheRiver. The maximum flood flow at Zhangfang Hydrological Station in theupper reachesoftheJumaheRiverwas2570m3/s;themaximumfloodflowatLuobaotanHydrologicalStationinthesouthernJumaheRiverwas2 520m3/swithfloodvolume50millionm3.Whenthefloodwent40kmdownwardstotheBeihedian,itsmaximumflowreducedto120m3/s,and thefloodvolumetherewas18.62millionm3.Accordingtotheanalysisonhistoricalfloods,thetremendouschangesoftheparametersofrunoff yield and flow concentration in the tributaries of the Daqinghe River took place, which could directly influence the calculated flood results.关键词
