Abstract: The ultimate pur pose of sediment studies in the U.S. Army Engineer District , Vicksburg, is to develop a workable knowledge of the basic principles controlling the transport of sediment in the Lower Mississippi River and to apply this knowledge toward effective and economical stabilization works for flood control and navigation. The more immediate purpose of this report, however, is to present the data that have been collected and analyzed·to date (1929-1974) and to show what trends exist in the quantities and sizes of suspended and bed sediments for the Vicksburg District. For this report, measurements of all available bed-material samples are presented, but presentation of suspended sediment measurements has been limited to data collected at the three main discharge ranges since data at these ranges have been collected at regular, frequent intervals. Some analysis of the data is made , but no theoretical aspects of sediment transport are presented. The information presented in the tables and graphs of this report may be considered as a step toward the realization of the ultimate purpose of sediment studies in the Lower Mississippi River. Previous reports that include information on the fluvial sediment for the portion of the Mississippi River under jurisdiction of the Vicksburg District may be found in References 1 through 9. Because the Mississippi River is an alluvial river , it is a very dynamic system which adjusts its widths, depths, slopes, and meander sizes according to the sequence of water discharges imposed on the system, the sequence of sediment discharges acquired from erosional and degradational processes, and the proneness of the banks to erosion or deposition. Any major changes, either natural or artificial, in the shape, pattern, or alignment of the channel involve the transportation and redistribution of large quantities of sediment. Consequently, most of the problems encounter ed in channel maintenance are caused by the movement of sediment into and within the system. Therefore , a knowledge of the magnitude and trends of sediment movement is necessary for designing an efficient navigation and flood control channel. NOTE: This file is large.
