In this study, 1:250,000- and 1:24,000-scale digital soil databases for Kansas were compared statistically and spatially. The soil attributes used in this comparison were soil permeability, percent clay, and hydrologic group. Results indicate that, although the two databases were correlated, the potential exists for substantial site-specific variability between them. The largest...

Channel-bed elevation changes were assessed downstream from 24 large Federal reservoirs in Kansas using information from U.S. Geological Survey streamflow-gaging stations. Changes in river/stream stage associated with mean annual discharge indicated that channel-bed lowering had occurred downstream from most of the reservoirs. The net decrease in channel-bed elevation ranged from less...

Reservoir-sediment cores were used to investigate sediment quality in two adjacent basins in the central Great Plains. A total of 18 metals were analyzed to determine and compare concentration magnitudes and trends within and between the two basins. Temporal patterns (bottom to top of core) and ranges in metal concentrations were similar between the two basins; spatial patterns (upstream...

The stability of the Neosho River channel downstream from John Redmond Dam, in southeast Kansas, was investigated using multiple-date aerial photographs and stream-gage information. Bankfull channel width was used as the primary indicator variable to assess pre- and post-dam channel change. Five six-mile river reaches and four stream gages were used in the analysis. Results indicated...

This digital spatial data set provides information on the magnitude and spatial pattern of depth-weighted, mean soil permeability throughout the State of Kansas. The data set was assembled using 1:24,000-scale cartographic and attribute information on the spatial distribution and characteristics of Kansas soils. The data set is in grid (raster) format with a grid-cell size of 10,000...

This digital spatial data set provides information on the spatial distribution of potential runoff-contributing areas in the State of Kansas. Potential runoff-contributing areas were estimated collectively for the processes of infiltration-excess overland flow and saturation-excess overland flow. For infiltration-excess overland flow, various rainfall-intensity and soil-permeability...

Digital topographic, soil, and land-use information was used to estimate potential runoff-contributing areas in Kansas. The results were used to compare 91 selected subbasins representing slope, soil, land-use, and runoff variability across the State. Potential runoff-contributing areas were estimated collectively for the processes of infiltration-excess and saturation-excess overland...

Digital topographic and soil information was used to estimate potential runoff-contributing areas throughout Kansas. The results then were used to compare 91 selected subbasins representing soil, slope, and runoff variability. Potential runoff-contributing areas were estimated collectively for the processes of infiltration-excess and saturation-excess overland flow using a set of...

The purpose of this report is to characterize the geomorphic (channel-changing) effects of overflow dams on the lower Neosho River channel in southeastern Kansas. Specifically, the report describes the types, upstream and downstream extents, and stability of the geomorphic effects in relation to site-specific, human-caused and natural conditions that may affect the channel’s response to...

The stability of the Neosho River channel downstream from John Redmond Dam, in southeast Kansas, was investigated using multi-date aerial photographs and stream-gage information. Bankfull channel width was used as the primary indicator variable to assess pre- and post-dam channel change. Five 6-mile river reaches and four stream gages were used in the analysis. Results indicated that the...

Digital soils and topographic data were used to estimate and compare potential runoff-contributing areas for 19 selected subbasins representing soil, slope, and runoff variability within the Kansas-Lower Republican (KLR) River Basin. Potential runoff-contributing areas were estimated separately and collectively for the processes of infiltration-excess and saturation-excess overland flow...
