I need to route VIC hydrological model, and the routing program read
AGNPS style flow direction.
I tried to run r.watershed on my srtm watershed, and after a week, I
just stopped it,
because I needed the PC for other processing.
(it was doing it, but slower and slower as it passed 60% in 3 days,
65% in 4 days etc...)
Now I am getting onto r.terraflow for flow direction,
but what i need is AGNPS output,
what is the flow direction type in r.terraflow format please.

FWIW, it could speed up again and also it could finish well before 100%.
It is slow but it gets there. (for trial and error method to find the
right threshold value, you might try at a low res first then scale?)

r.terraflow uses MDF, see the pic in the r.terraflow help page and -s
flag.
