Abstract: Drilling for laboratory testing of concrete and foundation rock was carried out for the U. S. Army Engineer District, Chicago, as part of a major rehabilitation program at the Starved Rock Lock and Dam. The structures are on the Illinois Waterway. This report covers the work accomplished during the Phase II program entitled "Compliance and Scour Detection."

Abstract: The model study was conducted to evaluate the characteristics of flow in the inlet channel, original sump, energy dissipator (saxophone outlet), and outlet channel and to develop practical modifications required for improving the hydraulic performance of the structure.

Abstract: Prototype studies were conducted to measure pressures in the filling and emptying culvert system and to monitor various other parameters relating to the operation of the new John Hollis Bankhead Lock.

Abstract: This model study was conducted to evaluate the characteristics of inflow conditions into an existing pump sump that would result with increased discharge capacity due to installation of the three proposed pumps and to develop modifications, if needed, within the confines of the present sump to improve flow distribution to the pump intakes.

Abstract: "The investigation reported herein describes surface and subsurface horizontal and vertical control, sampling, testing, laboratory testing, and analyses performed to determine the stability of a rock fill over fat clay deposits (South Fill) bordering the Hudson River at the West Point Military Academy, West Point, New York. The South Fill area in its present configuration was found to be stable and should remain stable provided use is limited to parking, athletic fields, and recreational areas. The report contains documentation of data collected since the monitoring program began in 1961."
