NAME

r.runoff (G-language) Generates an SCS curve number runoff map layer. It is a command-line interface for generating the runoff map by the SCS method.

SYNOPSIS

r.runoff rf=rainfall_map cn=cn_map ro=runoff_map

Parameters:

rf=map
rainfall map name in mm
cn=map
CN map name
ro=map
output runoff map name in *100 mm
The command-line ordering can be in any form but all key words must be there to run the program.

EXAMPLE

r.runoff rf=rainfall_map cn=cn_map ro=runoff_map
will create a runoff map runoff_map

NOTE

The r.runoff program is sensitive to the current window setting. Thus the program can be used to generate a runoff map of any sub-area within the full map layer. Also, r.runoff is sensitive to any mask in effect.
