The program does not work correctly if Manning's roughness grid is
defined as double (float expected). To define a simple uniform
roughness distribution try: r.mapcalc 'roughness = 0.1f'

-The region has to be set one row and column larger than the elevation
-map. See the example below to see how to do that with g.region.
