Book Description
This investigation is part of a general model study to determine the effectiveness of dike systems proposed for improvement of troublesome reaches on the Mississippi River. This report describes and gives results of tests concerned with the development of plans for the improvement of dthe Buck Island reach of the river, which is located about 700 river miles above Head of Passes. A movable-bed model reproducing approximately 12.5 miles of the Mississippi River to a horizontal scale of 1:3000 and a vertical scale of 1:100 with crushed coal as the bed material was used to develop plans that would improve and stabilize the navigation channel through the reach and eliminate or reduce the need for maintenance dredging. The Buck Island reach is a straight reach of river where dike fields have been constructed to form a sinuous navigation channel. During the Mississippi River flood of 1973, failure of two dikes resulted in the forming of a new smaller channel that was not deep enough to allow navigation during low flows. Plans tested in this hydraulic model study included improvement and stabilization of the prefailure navigation channel alignment and realignment of the reach to eliminate the crossings. Model result indicated that the original channel alignment could be restored by rebuilding Buck Island dikes 3 and 4; however, some dredging may be required near Commerce Bend.

Book Description
The Devil's Island Reach of the Mississippi River is located about 5 miles upstream of Cape Girardeau, Missouri, between miles 55.0 and 68.0. A movable-bed model with scale ratios of 1:400 horizontal and 1:100 vertical, reproducing approximately 13.0 miles of the Mississippi River, was used to develop a channel of project dimensions through the reach. Results of the investigation indicated that: Contracting the channel in this reach to a control width of 1500 ft should generally provide adequate channel depths and alignment, except that special treatments might be required in crossings depending on the channel alignment and degree of sinuosity provided in the improvement plan. The control width can be reduced to less than 1500 ft to improve the depth and alignment of the channel over crossings with dikes of lower elevation than those used for the 1500-ft contraction. The cost of dike construction can be reduced by use of the stepped-down principle in the design of dike systems. (Author).
