A numerical model study was conducted to evaluate the effect that reducing bank erosion between Arthur City, TX, and Index, AR, would have on deposition rates in the J. Bennett Johnston (Red River) Waterway. This was accomplished by evaluating measured sediment data and by using the HEC-6W numerical sedimentation model. Deposition rates in the navigation pool upstream from Joe D. Waggonner Jr. Lock and Dam (Lock and Dam No. 5) were predicted for existing bank erosion conditions, and for conditions where existing bank erosion was reduced by 50 and 100 percent.
