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

KEYWORDS
       raster, hydrology, rainfall, soil, erosion

SYNOPSIS
       r.usler
       r.usler --help
       r.usler  input=name  output=name method=string  [--overwrite]  [--help]
       [--verbose]  [--quiet]  [--ui]

   Flags:
       --overwrite
           Allow output files to overwrite existing files

       --help
           Print usage summary

       --verbose
           Verbose module output

       --quiet
           Quiet module output

       --ui
           Force launching GUI dialog

   Parameters:
       input=name [required]
           Name of annual precipitation raster map [mm/year]

       output=name [required]
           Name for output USLE R raster map [MJ.mm/ha.hr.year]

       method=string [required]
           Name of USLE R equation
           Options: roose,  morgan,  foster,  elswaify
           Default: morgan
           roose: Roosle (1975)
           morgan: Morgan (1974)
           foster: Foster (1981)
           elswaify: El-Swaify (1985)

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).

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

EXAMPLE
       TBD.
