Description :
This paper describes and assesses : 1) the use of a new instrument for the determination of three-dimensional flow velocities in natural rivers, the acoustic Doppler velocimeter (ADV); and 2) a method for positioning and orienting such measurements relative to a single local coordinate system to relate flow velocity factors with the bed and water surface. The ADV uses the Doppler shift priciple to measure the velocity of small particles , assumed to be moving at velocities similar to the fluid.
