ADCP is a new flow measurement system that uses the acoustio Doppler effect to measure the flow of rivers.In this paper，on two hydrologic station named YaoXiaBa(Ⅱ)and Bashang which affected by the backwater of the downstream sluice dam，we carried out the flow measurement and analysis of three sets of hydrometric cableway flowmeter，online ADCP and the walking ADCP.Established the relationship between the results of three kinds of flow measurement schemes，obtained the results of measured flow and flow data of online ADCP and the walking ADCP，analyzed the applicability of the walking ADCP and online ADCP to two station flow test.
