Abstract:

An inventory study concerning available stream sedimentation and flow data for the GREAT II Great River Environmental Action Team II watershed was conducted for the Sediment and Erosion Work Group of GREAT II. The study area covered the Upper Mississippi River and its tributaries between Guttenberg, IA, and Saverton, MO. These data were utilized to obtain rough estimates of annual sediment yields at individual sediment sampling stations by simple correlating monthly averaged suspended-sediment discharges with monthly averaged stream discharges. Based on these estimates, major sediment source areas were identified, and recommendations regarding installation of new sediment sampling stations for further baseline data were made. A review of some existing methodologies in estimating sediment yields also was made, and a plan of study to determine quantities of sediment delivered by tributary sources into the Mississippi River was proposed.
