Soils - Potential Runoff 2000

This digital spatial data set provides information on the spatial distribution of potential runoff-contributing areas in 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 values were used. For saturation-excess overland flow, antecedent soil-moisture conditions and a topographic wetness index were used. The digital data sets used in the analysis included 1:24,000-scale soils data (U.S. Department of Agriculture, Natural Resources Conservation Service, 1996) and the U.S. Geological Survey (USGS) 100-meter-resolution digital elevation model (DEM) (U.S. Geological Survey, 1993). The data set of potential runoff-contributing areas is in grid (raster) format with a grid-cell size of 10,000 square meters.
