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

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.
