Book Description
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).

Book Description
To test the applicability of various one-dimensional sediment-transport numerical models of movable-bed channels to Pool 20 to the Mississippi River, detailed field data were first collected, and several numerical models were subsequently evaluated using these field data. Chapter I describes the detailed results from a sediment sampling field study conducted in 1978 near Buzzard Island (RM 347-55) in Pool 20 of the Mississippi River. Variations in the longitudinal and transverse distributions are presented for various flow quantities and sediment characteristics, and are analyzed in connection with the prevalent shoaling problem in the Buzzard Island study reach. Chapter II evaluates the performance of four mathematical simulation models which used the data from a complimentary field study conducted in 1976 to establish the initial conditions when predicting the 1978 conditions. The four models evaluated were: (1) the HEC-6 model provided by the Hydrologic Engineering Center, U.S. Army Corps of Engineers; (2) the SUSR; (3) UUWSR models employed at the Colorado State University; and (4) the CHAR2 model used by the Sogreah consulting firm in Grenoble, France.
