Velocity Mapping with ADCP in the Illinois River and Des Plaines River

Water velocities were measured in the Illinois and Des Plaines Rivers using a Teledyne Rio Grande 1200 kHz acoustic Doppler current profiler (ADCP). ADCP data were collected in reciprocal pairs along cross-sections and along approximately streamwise-oriented lines between crosssections at the following locations: (1) the confluence of the Fox River and the Illinois River near Ottawa, IL on November 4, 2015 (2) immediately downstream of Starved Rock Lock and Dam on the Illinois River near Utica, IL on May 22, 2015 (3) the Dresden Island Pool of the Des Plaines River on July 31 – August 1, 2013 (4) the Marseilles Pool of the Illinois River on May 14-15, 2013 and May 28, 2013 The WinRiverII classic ASCII output file and KML files are provided for each ADCP transect. The classic ASCII output files may be imported into the Velocity Mapping Toolbox (https://hydroacoustics.usgs.gov/movingboat/VMT/VMT.shtml) for processing and visualization. The velocity data were collected as part of the GLRI velocity mapping project for the Illinois River.
