# usle\_c\_min

The minimum C factor can be estimated from a known average annual C factor using the following equation (Arnold and Williams, 1995):

$$C\_{USLE,mn} = 1.463 \* ln⁡\[C\_{USLE,aa}] + 0.1034$$

where $$C\_{USLE,mn}$$ is the minimum C factor for the land cover and $$C\_{USLE,aa}$$ is the average annual C factor for the land cover.
