Hello:
Has someone implemented succesfully the DRASCTIC model
for vulnerability of groundwater to
contamination in grass? I will like to hear
your experiences.
Thanks

Several have done this. Two that come to mind are:
Mary Leigh Wolfe (Virginia Tech Univ, done while at Texas A&M)
Brian Cooper, cooperb@ecn.purdue.edu (Purdue Univ)
As best I remember, DRASTIC is just an index computed
by weighting several layers---something done very easily
in r.mapcalc.

Dear Alejandro,
we did some work with DRASTIC.
We studied the growndwater vulnerability of the LUCCA plain (Tuscany -
Italy) in an area of about 200 km2.
The DRASTIC classes were overlaid on actual and planned landuse maps to
highlight the "geological settings x landuse" worse combinations where
detailed management models had to be run.
The DRASTIC model were obtained using both IDRISI (for DOS) and GRASS (on
Linux). We did not use particular scripts using r.mapcalc and we found
GRASS to be quite powerful, a little bit less user-friendly than IDRISI
(but we were then newcomers in the GRASS world), but infinitely more
effective than IDRISI as regarding printing (....ok, it was an unfair play!).
Please let me know if you need more infos.
Ciao.
Antonio Lo Porto

The above points of view are just mine and not my employer's ones,
although they should be.
