Hi Stephen,
I actually am fighting against almost the same problem, so let's do it
together :)
I found that r.strahler.sh works well to delineate streams and correct
topology, (I use a treshold of 1km^2, it works well but don't ask me why
:) ), but (in my little experience) does not work to order streams, so I
must run v.strahler after r.strahler.sh.
I know it's a very small hint but hope this helps.
Best

I have a low relief area in the costal plain of georgia that I am trying
to produce a topologically correct stream network. There are many breaks
in the flow accumulation grid and I would like to delineate the streams
and "correct" the topology after r.thin and r.to.vect have been
preformed so that I can then use v.strahler to order the streams. Thanks
for any help and I will provide and data that would be helpful. thanks,
