[GRASS-user] [GRASSLIST:1169] Flow accumulation revisited (MFD + cost surface)

[Jonathan Greenberg]

So I'm in a bit of a quandary here -- I want to use a MFD flow algorithm,
but I want it used on a surface of precipitation (so the accumulation isn't
calculating "number of pixels", rather a "real" value).  r.watershed allows
me to assign a surface value, but isn't MFD.  Is anyone aware of any
algorithms that do both (use MFD and per-pixel values), either in GRASS or
Arc (or in some other package?)  Thanks!
