Soil erodibility is one of the six components affecting water erosion of the universal soil loss equation (USLE). K-factor is best obtained from direct measurements on natural plots. This is an infeasible task on large scales. To overcome this problem measured K-factor values have been related to soil properties and the soil classification maps are used. The current research examines the ability of the soil maps for calculation of erodibility factor in the watershed scale. This subject was followed by investigation of difference of erodibility components among the soil types of Darabkola Watershed. Also, geostatistical technique with Kriging method are used for representation of the spatial distribution of K-factor. Results showed that among the K-factor components, percent of silt, structure class and permeability had significant difference between some of soil types, and other components and K-factor didn’t have significant difference. In conclusion any coincidence seemed between erodibility map and soil types map.
