  Using r.watershed specifying the input DEM and a name for the drainage map
I can view the drainage map. When I follow this command with r.water.outlet
specifying the drainage map as input, 'watershed' as the output map name,
and the coordinates of the designated outlet, no map is displayable.

  Could this be due to the very flat nature of the terrain?


Yes. The watershed computed via r.water.outlet may be only a single pixel
in size, if your outlet point is not located on a stream. Better use
r.watershed.
