Hei Helumt,
In that case I would probably try r.param.scale in order to identify flat
areas at maybe different scale levels.
V-valleys have a higher variation in aspect at the bottom (sides are
almost facing each other and nearly meet at the lowest point in a
V-valley). While
Hi Helmut,
After a second thought on this, personally, (given that I understood your aim
correctly) I would probably use a workflow like:
r.watershed in order to extract the streams (which are not unlikely to meander
or split up into different courses in wider U-valleys)
r.stream.distance in

Hi Stefan,
thanks your response.
If you think of valleys in a hydrological perspective I would have a look
at r.stream. modules for having a kind of threshold above streams (in m),
and then use r.grow.distance for an inverted valley representation.
If you think of valleys in a geomorphometric
