Derived from 1:250,000-scale USGS HUC 8 boundaries, this dataset represents the soil erodibility for the western USA. A weighted average was created for each HUC 8 watershed using approximate EMAP physical habitat substrate criteria. The values are based on the Universal Soil Loss Equation: A =R x K x LS x C x P, where A = potential long term average annual soil loss in tons per acre per year, R = rainfall and runoff factor by geographic location, K = soil erodibility factor, LS = slope length-gradient factor, crop/vegetation and management factor, and P = support practice factor. This dataset contains attribute fields with values for each factor.
