Abstract: The sedimentation study conducted on the Redeye Crossing Reach of the Mississippi River about 3 miles downstream of Baton Rouge, LA, was a combination of numerical and physical movable-bed model studies to aid in the development of a satisfactory dike design for this reach. A two-dimensional numerical model, TABS-2, was used to predict the reduction in dredging that could be anticipated with the original dike design and subsequent modifications. Those modifications included changing the length, height, location, and number of spur dikes. The plans investigated addressed the required dike plan to maintain the existing 40-ft navigation channel through the reach and an enhancement of that plan to provide a 45-ft channel to be developed in the near future. Since no dikes presently exist in this portion of the Mississippi River, the physical movable-bed model study was also conducted to take advantage of the capabilities of both types of models. Thus the overall study allowed use of the numerical model to screen plans and the physical model to address detailed impacts of the plans. The physical model was constructed to a horizontal scale of 1:240 and a vertical scale of 1:200 including the river channel and overbank areas to the adjacent levees. During the overall testing program the numerical model was used to refine and test dikes plans. The dike plans deemed most successful from the numerical sedimentation model were also tested on the physical model.
