Acoustic Doppler current profiler velocity and discharge measurements collected in and near the lock chamber of Brandon Road Lock and Dam, Joliet, Illinois, USA in December 2014

Water velocities and discharge were measured in the lock chamber and immediately downstream of Brandon Road Lock on the Des Plaines River at river mile 286 on December 9-10, 2014 using Teledyne RDI Rio Grande 600 and 1200 kHz acoustic Doppler current profilers (ADCP). The data were georeferenced with a differential GPS receiver with submeter accuracy. These ADCP measurements were collected in support of the US Army Corps of Engineers Great Lakes and Mississippi River Interbasin Study (GLMRIS). Velocity measurements were processed using the Velocity Mapping Toolbox (Parsons and others, 2013) to derive temporally- and spatially-averaged water velocity values. Discharge measurements were processed with the QRev discharge computation and review software (Mueller, 2016).
