Comparison of a Standard Current Meter Discharge Measurement Technique to Onethat Uses an Acoustic Doppler Current Profiler (ADCP) to Measure Discharge

摘要

The Vicksburg District monitors multiple gaging stations along the MississippiRiver using conventional methods. The Hydraulics Laboratory at the Waterways Experiment Station was contracted by the Vicksburg District to evaluate the discharge measurement technique against a new technique using an Acoustic Doppler Current Profiler. A testing plan was developed to compare these two techniques over two different flow conditions. The focus of this report is to present the data from both exercises, describing how the two methods calculate discharge through a cross section and identifying possible sources of error.
