Analysis of the Calibration of Flow Test in Gaoling Sluice During Withered Water Period
The accuract calibration of gate flow coefficient is an important basis for flow calculation and water resource scheduling.By using the navigational ADCP method,the water level and discharge data of Gaoling sluice at the junction of Zhanjiang and Maoming are obtained,and the coefficient of gate discharge,the relative opening of gate and the relationship between gate opening and discharge are analyzed.The results show that the correlation coefficient between the relative opening of the gate and the flow rate and the relationship between the opening of the gate and the flow rate is above 0.97,and the correlation coefficient between the opening of the gate and the flow rate is above 0.99,and the scheme is more intuitive to push the flow,so it is recommended to use the relationship between the opening of the gate and the flow rate to push the flow.
