Description: Laboratory Study
From the Introduction: The first part of this report presents the results of study of the elements of meandering rivers - the basic principles. It sets forth the results of tests with analysis and discussion as to the causes of meandering; the development of a meandering course and the characteristic cross sections; the source, path of travel, and location of deposition of sand; the role of sand entering at the head of a meandering river, and of sand entering from the caving banks; the effects of discharge, slope and alignment on the size and shape of bends; the degree of sinuosity; the importance of the rate of bank erosion; the interrelationships between the variables; the limiting width and length of meanders; the formation of chutes; the causes of natural cut-offs; and the braiding of rivers. Finally, a general discussion is given to show how all of the major elements and other aspects work together in the meandering of the Lower Mississippi River as indicated by this study. The second part presents the principles involved as to the effects of stabilizing the caving banks of a meandering river. First, it sets forth the results of stabilizing the banks of naturally formed meanders consisting of a series of nearly uniform bends; that is, the changes brought about in channel capacity, depths of cross sections, and alignment of the small-scale rivers. Second, it sets forth the results of stabilizing the caving banks of a small-scale meandering river which had the alignment of a section of the Lower Mississippi River. Also included in the second part are the results of tests to indicate whether stabilization of the banks of a river should progress upstream or downstream. In the third part, the general testing methods, the materials used, and the measuring devices are described. Also included in this part is the technique which was developed toward making erodible-bank model studies.
