Channel geometry, banklines and floodplain inundation over a range of discharges in two segments of the Missouri National Recreational River, South Dakota and Nebraska, 1955-2018
September 7, 2022
These datasets describe channel adjustments over a 60-year period to dams in the Missouri National Recreational River (MNRR), South Dakota and Nebraska. Datasets include a channel geometry analysis from cross-sections, banklines digitized and interpreted to predict future bank erosion sites from aerial photography, and models of floodplain inundation over a range of discharges. There are two MNRR segments, a 39-mile segment downstream from Fort Randall Dam, and a 59-mile segment downstream from Gavins Point Dam. Similar datasets were analyzed for each MNRR segment using similar methods.

Sixty years of channel adjustments to dams in the two segments of the Missouri National Recreational River, South Dakota and Nebraska
The Missouri National Recreational River (MNRR) consists of two Missouri River segments managed by the National Park Service on the border of South Dakota and Nebraska. Both river segments are unchannelized and maintain much of their pre-dam channel form, but upstream dams have caused reductions in peak flow magnitudes and sediment supply. The 39-mile segment is located between Fort Randall and Ga
