thanks to Helena for the suggestion of use accumulation map and then
r.mapcalc (I knew this method but I didn't remember it :-( )
the problem is that, also using this method, the ram wasn't enougth..
at the moment we have solved using another PC (13 GB of RAM)... and the
process is still running... after 3 days...
but if I will find alternatives I will let you know...
many thanks to all...
