Re: [GRASS-user] Average raster value of the upslope contributing area,

Hi Pierluigi, I think here you could use the tool r.watershed ( https://grass.osgeo.org/grass70/manuals/r.watershed.html) with your underlying DEM as input. This tool will provide you an accumulation map with increasing values in downstream direction. I am not exactly sure if this is your task,
