Book Description
In connection with the MRC Potamology Program, movable-bed models studies were conducted of seven of the most complex and troublesome reaches of the Mississippi River to obtain some quick general indications of the effectiveness of plans proposed for the improvement and stabilization of those reaches. Because of the limited time available, the studies were conducted in an existing facility with little or no adjustment of the models and in some cases without a base test. Because of the limited size and shape of the facility available, only a relatively short reach of the river including the problem could be reproduced in each model with little or no overbank areas. The horizontal scales varied with each reach depending on its size and shape and were much smaller with a higher distortion of the linear scales than was considered desirable for studies of this type. An analysis of the model results compared with developments in the river based on an evaluation of considerable prototype data indicated that the types of models used predicted, at least qualitatively, most of the principal trends that actually occurred in the river with the plans tested. The degree of accuracy of the models varied and depended to a considerable extent on the model adjustment, characteristics of the reach, flow conditions, and similarity between plan tested and actual construction.

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.
