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

[Ing. Pierluigi De Rosa]

Dear users,

my deal is to calculate a raster of the sediment delivery ratio like
explained here: 
http://data.naturalcapitalproject.org/nightly-build/invest-users-guide/html/sdr.html#sediment-delivery-ratio

moreover I need to calculate, for each cell, the average of a raster (C
factor) of the upslope contributing area.
take a look to these image to better explication:

How can I do that?
Thanks
Pierluigi
