Hallo, my name is Stefano
i have 2 simple questions:
1) I'd like to know which is the best distribution for use with GRASS.
2) I've found some pages about integrations between GRASS and modeling
programs (water quality and quantity, groundwater modeling), but i couldn't
find any reference to available code (not only free byt also to be paied):
is it available?
Thanks a lot

Stefano,
There is no `best' distribution. GRASS runs well on linux, solaris,
freeBSD, IRIX and probably a few others. In the linux world, may folks (us
included) run it on Red Hat. One of my associates is running it on S.u.S.E.
There is no reason it will not run on any distribution.
If you are referring to a GRASS distribution, then you have a choice of
two: 4.3 is the most comprehensive (it is the GPL version of 4.2.1 with some
more bug fixes) but lacks floating point number capability. The new version
5 has floating point capabilities and much more, but it's still in the beta
stage and not all modules of the earlier versions have been ported to the
new one. Your choice depends on what you want to do -- or need to do.

You need to search for the links, or for the references themselves. Some
of the models (I believe the agricultural hydrology ones) are included with
the GRASS distribution. SWAT (which we'll be using) has its own web site:
<http://www.brc.tamus.edu/swat/>\.
Now that GRASS is released under the GPL, all integrated and associated
models should also be available in source code form. With some luck.

Stefano,
Rich is right, there is no "best" distribution of GRASS. We maintain
both floating point (5.0) and non-floating point (4.x). There are
many water resources and environmental models that are linked to
GRASS. (see http://www.baylor.edu/~cagsr/swat for example)
and we do not as a rule maintain any of that type of code within the
general release. HOwever, most of these types of packages are
readily available.
The reason for maintaining both fp and non-fp versions is that many
users have data and scripts that they have not moved to be fp version
compatable. We will continue to maintain two versions indefinately
for this reason.
If you have any questions, feel free to contact me.
