NOTE:
Acoustic Doppler Current Profiler (ADCP) and Current Meter (CM) measurements are likely to differ at high flow due to the occurrence of a moving bed during the measurement. This can be corrected either during the measurement through the use of a GPS for positioning, or after measurement collection through application of a correction factor based on a loop-test.
Discharge measurements collected by the DSMP using ADCP HAVE NOT BEEN CORRECTED and may therefore underestimate discharge at high flow velocity rates. See DSMP Monitoring Review Report for more information
