based on soil texture, organic matter, soil structure and soil permeability obtained from national soil map and land use project in Jordan,
L is the slope length factor which is the ratio of soil loss from the field slope length to soil loss from a 22.1 m length under the same conditions,
S is the slope steepness factor which is the ratio of soil loss from the field slope gradient to soil loss from a 9% slope under the same conditions In this study we used the DEM of 90 m resolution to calculate
