Standard operating procedures for mid-section open water discharge measurements using ADCPs / P Campbell.: En56-303/2015E-PDF
"Acoustic Doppler current profilers (ADCPs) are typically used for measuring river discharge from a floating platform or boat that is continuously moving across the river from one bank to the other. A hydrographer can also use ADCP’s to measure river discharge using the mid-section method in which the ADCP is held in place for a specified duration at multiple discrete locations, or verticals, across the stream. Water velocity data is captured throughout the depth of flow and averaged to obtain a mean velocity estimate integrated over the full depth at each vertical. The depth for each vertical is determined with the ADCP, and representative areas and discharges for each vertical are calculated and summed to obtain a total discharge. This document presents guidance and standard operating procedures specific to deploying ADCPs for open water mid-section measurements"--Introduction, page 2.
