Quality Assurance Plan for Discharge Measurements Using Broadband Acoustic Doppler Current Profilers

By Stephen W. Lipscomb

Abstract

The recent introduction of the Acoustic Doppler Current Profiler (ADCP) as an instrument for measuring velocities and discharge in the riverine and estuarine environment promises to revolutionize the way these data are collected by the U.S. Geological Survey. The ADCP and associated software, however, compose a complex sys-tem and should be used only by qualified personnel. Standard procedures should be rigorously followed to ensure that the quality of data collected is commensurate with the standards set by the Water Resources Division for all its varied activities in hydrologic investigations.
