Velocity profiling at the US Army Corps of Engineers Electric Dispersal Barrier in the Chicago Sanitary and Ship Canal during passage of fully loaded commercial tows: Wall Mounted Argonaut SW in August 2016

In 2016, the U.S. Fish and Wildlife Service, U.S. Geological Survey, and U.S. Army Corps of Engineers undertook a large-scale interagency field study to determine the influence of commercial barge vessels on the efficacy of the Electric Dispersal Barrier System (EDBS) in the Chicago Sanitary and Ship Canal (CSSC) in preventing fish passage. This study included a series of trials in which a tow, consisting of a tug vessel and six fully-loaded barges, transited the EDBS in both upstream-bound (n = 23) and downstream-bound (n = 22) directions. A 3,000 kHz SonTek Argonaut SW Acoustic Doppler Velocity Meter (ADVM), was mounted on the west canal wall at a depth of approximately 5.5 feet (1.7 meters), as measured on August 2, 2016 at 09:15 am CDT. The approximate elevation of the ADVM was 571.2 feet (NAVD88). The wall mounted instrument was located at (41.6423629, -88.060329). The provisional water surface elevation at the USGS streamflow gaging station on the Chicago Sanitary and Ship Canal ranged from 575.81 feet to 577.29 feet over the study period (August 2 to 11, 2016). The ADVM measured horizontal profiles of streamwise and cross-stream components of velocity between the edge of tow transiting the EDBS and the West canal wall for each trial. The ADVM reported velocities at 10 bins spaced by 0.5 meters between 0.57 and 6.07 meters from the West canal wall. All velocity measurements represent an average of 10 pings, recorded every 10 seconds during measurement, and are included in this data release as Comma Separated Value (CSV) files.
