Replying to [comment:7 lazaa]:
> I added flag {{{-l}}} for logarithmic legend. I hadn't any good data so
please feel free to test.

you can also just compute flow accumulation with
{{{
r.watershed -a elevation=elevation threshold=1000 accumulation=flowacc
}}}

I tested it by setting labels 1,10,100,1000 and there should be the same
distance between them, but it's not, so there must some mistake. See an
example of logarithmic legend [http://i.stack.imgur.com/7VvVB.png here].
