亳州市中小河流水文站堰闸流量系数率定及分析

Determination and Analysis of the Discharge Coefficient of the Weir Gate at Small and Medium River Hydrometric Stations in Bozhou City

亳州市谯城区十河闸、贾集闸水利枢纽自2018年拆除重建,两处中小河流水文站已配套运行5年。近年来,由于防汛调度工作对水工建筑物出流情况的精准把握需求,亟需通过水文测验及水文预报为地方防汛调度提供更加科学合理的数据支撑。而随着走航式多普勒流速仪(ADCP)的广泛投入应用,亳州水文勘测队积极投入到中小河流水文站的堰闸流量系数线的测验、率定、分析工作中。通过近两年对实测流量成果的分析,初步率定出堰闸流量系数线并通过了各项精度检验,适用性也得到印证,为地方的防汛调度和水资源管理提供科学依据。

Since the demolition and reconstruction of the Shihezha and Jiajizha water conservancy projects in Qiaocheng District,Bozhou City in 2018,two small and medium-sized river hydrological stations have been in operation for 5 years.In recent years,due to the need for accurate understanding of the discharge conditions of hydraulic structures in flood control dispatching work,it is urgent to provide more scientific and reasonable data support for local flood control dispatching through hydrological testing and forecasting.With the widespread application of the traveling Doppler current meter(ADCP),the Bozhou hydrological survey team has actively engaged in the testing,calibration,and analysis of the weir gate discharge coefficient line at the Zhongxiao River Hydrographic Station.Through the analysis of the measured flow results in the past two years,the weir gate flow coefficient line has been preliminarily determined and passed various accuracy tests,and the applicability has also been confirmed.Provide scientific basis for local flood control scheduling and water resource management.
