Velocity profiling in the Chicago Sanitary and Ship Canal near the US Army Corps of Engineers Electric Dispersal Barrier near Romeoville, Illinois

On August 31, 2015, USGS Illinois Water Science Center staff deployed a 2000 kHz side-looking acoustic Doppler velocity meter (ADVM) in the Chicago Sanitary and Ship Canal (CSSC) at the Electric Dispersal Barrier System (EDBS). These data were collected as a fully loaded commercial barge tow traversed the EDBS and passed the ADVM three times, and as several smaller vessels and an unloaded barge tow passed the ADVM. The ADVM was mounted to a rigid 2-inch PVC pipe in compliance with U.S. Army Corps of Engineers (USACE) operational safety protocols for working in or near the EDBS. The pipe with ADVM was lowered 4.5 feet below the water surface on the west (right) bank of the canal at a location approximately 477 feet upstream of the Romeo Road (135th Street) bridge (41.642050, -88.060383). The pipe was mounted to the walkway guard rail in a vertical orientation. An upstream and downstream guide line were used to provide additional tension to prevent movement or vibration on the PVC pipe. See more...
