摘　　要：选取运河水文站2020年实测流量资料进行落差指数法分析,发现滩上集站至运河站测验河段落差在0.4m以上时,基本水尺断面水位Z与校正流量因素q具有较好的相关关系.通过计算机模拟定线,可以实现运河水文站高效推流,为平原河道的高洪流量测验工作提供有益借鉴.Selecting the measured flow data of the Canal Hydrological Station in 2020 for the drop index method analysis,it is found that when the measured water level difference between the Tanshang Ji Station and the Canal Station is more than 0.4m,the basic water gauge section water level Z has a good correlation with the corrected flow factor q.Through the computer simulation of the route,calculating the flow can be achieved effectively,and it also provides a useful reference for the high flood flow tests of the plain rivers.
