[GRASS-dev] New addon r.accumulate calculates weighted flow accumulation using a flow direction map

Hi All,

I just committed a new addon r.accumulate (https://trac.osgeo.org/grass/browser/grass-addons/grass7/raster/r.accumulate). Unlike r.watershed, this module calculates weighted flow accumulation directly from the flow direction map and does not require the original elevation data. I wrote this module many years ago for GRASS 6, but I almost forgot about it until I read this question:

Thanks.
