Description

r.usler  calculates  USLE R factor for Rainfall erosivity. It enables several empirical equations: Roosle
       (1975), Morgan (1974), Foster(1981) and El-Swaify (1985).

Example

       TBD.

Keywords

       raster, hydrology, rainfall, soil, erosion

Name

r.usler  - Computes USLE R factor, Rainfall erosivity index.

Notes

r.watershed provides for USLE L, S, LS factors.
