The soil media layer is created by direct assignment of soil layer to S index values from 1-10. Rock outcrops frequently and there is little or no subsoil over much of teh catchment. The majority of the catchment is given the higher āSā-ratings due to lack of soil and subsoil cover, with areas of little or no soil given a value of 10.
