Hydrometry. Measuring river velocity and discharge with acoustic Doppler profilers subscription-only1 Scope Acoustic Doppler profilers are instruments and software packages used to measure water velocity, channel bathymetry, and river discharge. This Technical Specification gives the principles of operation, construction, maintenance and application of acoustic Doppler profilers to the measurement of velocity and discharge, and discusses calibration and verification issues. It is applicable to open channel flow measurements with an instrument
