[GRASS-user] [GRASSLIST:1095] Accumulating values from a second raster in a flow model

[Jonathan Greenberg]

Hi there -- what is the best/fastest way to generate 1) a flow
direction/accumulation model from a DEM, and then 2) accumulate values from
a DIFFERENT raster that correspond with the cell positions from the DEM --
basically I want to take a flow acc. model and apply it to a map of
per-pixel precipitation values to get a first-order estimate of per-pixel
water accumulation, assuming conductivity in all cells is the same.
