The ultimate purpose of sediment studies 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.

Download Characterization of the Suspended-Sediment Regime and Bed-Material Gradation of the Mississippi River Basin. Potamology Program (P-I). Report 1 Book in PDF, ePub and Kindle
The study reported herein is a component of the Potamology Program of the Lower Mississippi Valley Division. The Potamology Program is a comprehensive study of physical forces which influence the flood carrying capacity and navigability of the lower Mississippi River. The purpose of the Potamology Program is to define cause-and-effect relationships that result in short-term and long-term changes in the lower Mississippi River's stage-discharge relationships and to develop improved design concepts and criteria for construction of channel stabilization works which will improve flood control and navigation along the lower Mississippi River. The Potamology Program is composed of two major components: Sedimentation, Mississippi River Basin; and Aggradation and Degradation, Mississippi River. This study is one item under the Sedimentation component.

The Lower Mississippi River, extending from Cairo, Illinois to the Gulf of Mexico, annually transports approximately 170 million tonnes of sediment. Historically, the quantity and calibre of sediment derived from catchment erosion have been affected by changes in land-use and management. For example, soil erosion increased during the 19th and early 20th centuries due to settlement by Europeans and this may have elevated catchment sediment supply to the Mississippi River, while more recently the supply of sediment from tributaries is known to have decreased markedly as a result of river engineering and management. Specifically, the construction of large dams as part of the Mississippi River and Tributaries (MR & T) Project has trapped sediment that would otherwise have been supplied to the Mississippi, particularly by the Missouri River. Marked changes have also occurred in the extent of eroding bankline along the Mississippi and these must have reduced the input of sediment derived from this source. For example, during the last three decades, a sustained construction program of bank revetments and dikes has produced a stable alignment. Given these trends in sediment supply from catchment, tributary and bank sources, it is not surprising that most studies of sediment movement report a large decrease in measured sediment loads at selected monitoring stations along the Mississippi River over the last 50 years (Kesel, 1988; Dardeau and Causey, 1990). However, a case can be made that the bed material load must have increased since the 1940s. This argument is based on analysis of morphological changes observed along the river that have led to an overall increase in slope and available stream power, coupled with the fact that bed material sizes along the river have remained almost constant.

Download Field Study of Sediment Transport Characteristics of the Mississippi River Near Fox Island (RM-355-6) and Buzzard Island (RM-349-50) Book in PDF, ePub and Kindle
The field study was conducted in order to obtain a better understanding of the flow and sediment-transport mechanisms responsible for the recurrent shoaling that has been experienced in the vicinities of Fox Island (RM-355-6)and Buzzard Island (RM-349-50) in Pool 20 between Keokuk, Iowa, and Canton, Missouri, in the Mississippi River. Three sets of detailed data on transverse and streamwise distributions of flow velocity, suspended sediment discharge, bed-load discharge, bed-material properties, and flow depth were obtained for the high, intermediate, and low river stages during the period between May and September, 1976. The field data were used to establish empirical relationships between the sediment transport rates and hydraulic quantities in the study reaches. Based on the empirical sediment discharge formulas, closures of some side-channels to increase-transport capacity in the main channel of the study reaches have been suggested. (Author).
