Traces a flow through an elevation model or cost surface on a raster map. 

Usage: 
r.drain [-cand] input=name [direction=name] output=name [drain=name] 
[start_coordinates=east,north] [start_points=name[,name,...]] 
[--overwrite] [--help] [--verbose] [--quiet] [--ui] 

Flags: 
-c Copia i valori della cella in input sull'output 
-a Accumula i valori di input lungo il persorso 
-n Numera progressivamente le celle lungo il percorso 
-d The input raster map is a cost surface (direction surface must also be specified) 

Parameters: 
input Name of input elevation or cost surface raster map 
direction Name of input movement direction map associated with the cost surface 
output Nome del raster di output 
drain Name for output drain vector map 
start_coordinates Coordinates of starting point(s) (E,N) 
start_points Name of starting vector points map(s)
