Global Soil Erodibility - Williams K-Factor
Global raster for soil erodibility (USLE K factor) using the Williams K-factor calculation. This method implements the Williams 1995 method, referenced in several publications, including the SWAT 2005 documentation, equation 4:1.1.5, using global sand, silt, clay and soil organic carbon content raster data from ISRIC SoilGrids. The original equation creates results with U.S. customary units, and these have been converted to metric using the factor 0.1317, as described in Foster 1981.
