usle_c_min
Minimum value of the USLE C factor for water erosion
The minimum C factor can be estimated from a known average annual C factor using the following equation (Arnold and Williams, 1995):
CUSLE,mn=1.463∗ln[CUSLE,aa]+0.1034
where CUSLE,mn is the minimum C factor for the land cover and CUSLE,aa is the average annual C factor for the land cover.
