Abstract: In connection with the MRC Potamology Program, movable-bed model 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, 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 scale 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. The analysis of model and prototype data permitted an evaluation of the performance of various types of dikes and dike systems and some of the principles involved in the developments within alluvial streams.
