Prepared for U.S. Army Corps of Engineers, Louisville District Mazzoli Federal Building 600 Dr. Martin Luther King Jr. Place Louisville, KY 40201-0059 Under Project No. 455010, “The Silver Creek Floodplain Management Services Project: A Study of Stream Velocities and Erosion along the Ohio River near Clarksville, Indiana” ERDC/CHL TR-18-4 ii Abstract The River Engineering Branch of the Coastal and Hydraulics Laboratory conducted a two-dimensional numerical model investigation of the Ohio River immediately downstream of McAlpine Lock and Dam. The right bank between river mile 605.5 and 606.5 (opposite the dam’s downstream set of tainter gates) has historically experienced stability issues. Condit

Prepared for U.S. Army Corps of Engineers, Mississippi Valley Division Mississippi River Geomorphology & Potamology Program 1400 Walnut Street Vicksburg, MS 39180 Under Project 127672, “Bedload Measurement” MRG&P Report No. 18 ii Abstract The U.S. Army Engineer Research and Development Center, Coastal and Hydraulics Laboratory, Field Data Collection and Analysis Branch collected bathymetry data and water surface elevations during the 2011 Flood. According to the gage at Vicksburg, MS, the flood peaked at a stage of 57.1 and a flow of 2,310,000 cubic feet per second (cfs) on 17 May 2011, both the highest of record. The reported water surface data include a continuous water surface profile from river mile (RM) 597 to RM 362 and water surface measurements in the vicinity of the Yazoo Backwater levee and Vicksburg, MS. Bathymetry data were also collected and include five sets of surveys, compatible with the Integrated Section Surface Difference over Time Version 2 (ISSDOTv2) method of measuring bed-load transport. These five sets were surveyed at flow rates between 1.6 million and 2.3 million cfs. ISSDOTv2 was used to calculate bed-load transport for the five sets of data. These new bed-load data populate the Lower Mississippi River bed-load rating curve at higher flows and provide a higher level of confidence in the higher-flow portions of the curve. The resulting curve can be a
