Methodology and Interpretation

National Elevation Dataset
The Upper White River study area (21,848 km²) has varied topography throughout. The National Elevation Dataset (NED) has been developed by merging the highest-resolution, best quality elevation data available across the United States into a seamless format. Applicable portions of the NED are used to assess landscape condition among four 8-digit Hydrologic Unit Code (HUC) regions and 244 smaller subwatersheds of varying sizes, in an effort to determine the vulnerability of water quality throughout the area.
