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=nameA [required]
	   Name	of annual precipitation	raster map [mm/year]

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

       method=stringA [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.
