A Comparison of a Standard Current Meter Discharge Measurement Technique to One that Uses an Acoustic Doppler Current Profiler (ADCP) to Measure Discharge.

Abstract

The Vicksburg District monitors multiple gaging stations along the Mississippi River using conventional methods. The records for these stations date back for many years giving the Corps an excellent understanding of how the river discharge reacts to spring thaws and large scale storm events. These records provide the Corps with information to maintain and operate the navigable waterways along the Mississippi. As technology develops, the Corps is always eager to incorporate new technology into its operating plans, but not without extensive testing.The Hydraulics Laboratory at the Waterways Experiment Station was contracted by the Vicksburg District to evaluate the present 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.
