Uncertainty analysis of index-velocity meters and discharge computations at the Chicago Sanitary and Ship Canal near Lemont, Illinois, water years 2006–16
Monitoring discharge in the Chicago Sanitary and Ship Canal is critical for the accounting done by the U.S. Army Corps of Engineers of the diversion of water from Lake Michigan to the Mississippi River Basin by the State of Illinois. The primary streamgage used for this discharge monitoring, the Chicago Sanitary and Ship Canal near Lemont, Illinois (U.S. Geological Survey station 05536890), is ope

Manning's roughness coefficient for Illinois streams
Manning's roughness coefficients for 43 natural and constructed streams in Illinois are reported and displayed on a U.S. Geological Survey Web site. At a majority of the sites, discharge and stage were measured, and corresponding Manning's coefficients—the n-values—were determined at more than one river discharge. The n-values discussed in this report are computed from data representing the stream

Discharge measurements at U.S. Geological Survey streamgage 05536890 Chicago Sanitary and Ship Canal near Lemont, Illinois, 2005-2013
Discharge measurements made at U.S. Geological Survey Chicago Sanitary and Ship Canal near Lemont, Illinois, streamgage (05536890) between 2005 and 2013 were reviewed and manually processed using QRev v3.12. Discharge was measured using Acoustic Doppler Current Profilers (ADCPs) deployed from a moving boat according to the procedures described in Mueller and others (2013). QRev generates an extens
