Kankakee River Basin in Illinois: hydraulics, hydrology, river geometry, and sand bars interim report

This interim report summarizes the work completed within the first nine months of the project. This report summarizes all of the existing streamflow records for Illinois and for two stations from Indiana, lists the available literature, and describes the field trip to the site. Analyses of the bed and bank material samples collected during the field trip also are included. Maps of the bank lines from the Route 30 Bridge in Indiana to the confluence of the Kankakee River with the Des Plaines River have been completed and will be available with the final report. Bank conditions of the entire main stem of the Kankakee River from the Route 30 Bridge in Indiana to its confluence with the Des Plaines River are also summarized. This includes general bank conditions, shoreline stability, erosion sites and severity, pumping stations, log and tree jams, and other features. Additional work on the surveying of the river and sand bar geometries is now being done. A final report will be prepared that summarizes all of the existing and newly collected data on hydraulics, hydrology, sediment transport, bed and bank material distributions, and sedimentation patterns

Experimental studies of wing-wall mixing control

Detailed velocity traverses are presented for shallow submerged slot jets without lateral confinement. With wing-walls in place maximum velocities and temperatures were traced for both unheated and heated discharges. These tests were repeated for various wing-wall crest elevations and wing-wall lengths. For the wing-wall tests a typical Reynolds number based on slot width was 400,000 and a typical densimetric Froude number based on slot width was 40. Some flow combinations were found to be unstable and tests were conducted to delineate the limits of stability. The tests demonstrate that flow patterns may be controlled using controlled flow over wing-wall crests. A simple design procedure making use of the data is illustrated.U.S. Department of the InteriorU.S. Geological SurveyOpe
