Analysis of Artificial Channel Flow Test Based on ADCP and Point Current Meter
Accurate and efficient test of channel cross-section flow is the focus of hydrometry.In this study,we performed comparative tests in three typical sections of a water supply project in Xinjiang by ADCP and point current meter.According to the flow comparison data,we verified the feasibility of different test methods,and analyzed the difference in flow velocity and flow rate measured by the two methods.Results show that the accuracy of flow test by vessel-mounted ADCP and point current meter are both high.However,in test with large flow and large cross-section such as artificial channels,ADCP excels in large data collection and high efficiency,and has significant advantages in hydrometry.
