Determination of stream velocity by means of an acoustic Doppler instrument, which measures the velocity of the water based on the Doppler shift experienced by an acoustic pulse of energy which is reflected off particles suspended in, and moving with, the water. [Based on 'Acoustic Doppler Velocimeter' in Guide to Hydrological Practices (WMO-No. 168), Volume I. 2008 edition, updated in 2020.]
