Abstract: This report documents the development, calibration, and validation of a numerical model for the Racetrack Reach of the Mississippi River between the Vicksburg, MS, Interstate-20 Bridge and approximately 12 miles downstream conducted for the U.S. Army Corps of Engineers, Mississippi Valley Division, Vicksburg, MS. The investigation was conducted via a combination of historical field data collection and numerical modeling of the hydraulics and sediment transport. The objectives were to model flow conditions and sediment transport from 1965 through 1969 and compare to historical surveys from 1965 and 1969 on the Mississippi River. A detailed Adaptive Hydraulics model was developed for this reach of the river. The model domain extends from 10 miles upstream of the Mississippi River Bridge in Vicksburg, MS, to 24 miles downstream of the bridge and adjacent portions of the Mississippi River and its floodplain. Unsteady flow simulations were evaluated for the time from 1965 through 1969. For this particular model application, the Wright-Parker suspended sediment entrainment function and the Meyer Peter Mueller with Wong Parker Correction bed-load entrainment function results best replicated the depositional/erosion patterns and magnitudes. The choice of hiding factor did not have a noticeable impact on the results.
