A two-dimensional numerical model, TAB 5-2, 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. 收起
