Sediment and hydraulic measurements with computed bed load on the Missouri River, Sioux City to Hermann, 2014

Abstract

This work was performed to assist the U.S. Army Corps of Engineers, Omaha and Kansas City Districts, in quantifying sediment bed load and suspended load at several sites on the Missouri River for the purpose of defining sediment-discharge rating curves and for possible parameterization of bed-load transport equations. Seven sites were selected, and all sites were surveyed three times, separated by at least 4 weeks (or 20% flow difference) between surveys. Multi-beam, acoustic Doppler current profiler, suspended sediment, and bed material samples were collected for each site visit. As requested by the Districts, all units are in English units. In addition to quantifying all the intended data types listed above, bed-load transport values were computed for all sites and all trips using the Integrated Section Surface Difference Over Time version 2 (ISSDOTv2) method and compared with the Meyer-Peter Mueller and Einstein bed-load transport functions.The study provides a complete sediment picture (bed load, suspended bedmaterial load, and wash load) over a 630-mile reach of a large sand bed river, with seven sites representing increasingly larger flows along the river length. The data set will be very useful for additional studies. DISCLAIMER:The contents of this report are not to be used for advertising, publication, or promotional purposes.

“…We targeted datasets with suspended sediment concentration for multiple heights in the water column, laser-diffraction grain size analysis, water depth, and boundary shear velocity data. We used datasets analyzed by de Leeuw et al ( 2020) and Lamb et al (2020), and included additional datasets (Abraham et al, 2017;Baronas et al, 2020;Bouchez, 2022;Dingle, 2021;Dingle et al, 2020) (Table S1 in Supporting Infomation S1).…”

Bed-load measurements on large, sand-bed rivers in the United States

“…The Atchafalaya and Red River measurements can be found in the "Old River Control Complex Sedimentation Investigation" [4]. The Missouri River data was a part of the "Sediment and Hydraulic Measurements with Computed Bed Load on the Missouri River, Sioux City to Hermann, 2014" report [5]. When multiple measurements have been recorded at a specific location or on a certain river for varying flows, rating curves can be developed.…”
