The man page seems to imply that internal divided need digitized?
Much thanks,

I'm not sure if I understood you right:
the border of a watershed is unique, if you see the basin starting
from
outlet of a river into the ocean.
But there are unlimited subbasins (up to the resolution of the
raster)!
So you have to define a characteristic for the watersheds, eg. a basin
size from the threshold of r.watershed.

Upon first glance, r.basins.fill seems like a great tool to generate
subbasins within a watershed. Although I must not be understanding
something obvious and essential.
If one has to digitize in the internal ridges in a given watershed,
why run the ridge input through the module if one has essentially
just
delineated the subbasins ridges?
Is there an advantage to using a smaller threshold on r.watershed to
get smaller basin delineations (ceasing when thin strip basins get
introduced)?
Thanks for any feedback,
Mark
