You can use r.resample to create a new map at the coarser resolution.
Change the resolution to teh preferred one with g.region as you 
did before.  Then use r.resample to create a new map with this
as its resolution.  Each raster map includes information about its
inherent resolution.  The model you are using is probably reading
the resolution from teh cellhd/ file rather then the current region.
