摘要
海晏(三)水文站是湟水干流控制站,湟水海晏地区洪水主要由冰雪消融、暴雨造成,年内分配不均匀,差异较大。最大洪峰流量多发生在7、8月份,暴雨和洪水在时间上具有很好的相应性。结合流域洪水特性,从水位、洪水流量、泥沙含量测量等3个方面确定水文站测洪方案,可为类似工程提供参考。
Haiyan(III) hydrological station is the control station of the main stream of Huangshui.The flood in Haiyan area of Huangshui is mainly caused by ice and snow melting and rainstorm,with uneven distribution and great difference in the year.The maximum peak discharge mostly occurs in July and August,and the rainstorm and flood have good correspondence in time.Combined with the flood characteristics of the basin,the flood measurement scheme of the hydrological station is determined from three aspects:water level,flood flow and sediment content measurement,which can provide reference for similar projects.
