[GRASS-user] Modelling for groundwater

Hi all,
 I don't know what's wrong with the server on which my webpage is hosted. It was working yesterday, so hopefully it won't be long for it to be accessible again.
 The r.gmtg module works with grass 5.4 and modflow 96 (the latest modflow 96 version of 2000). I've thought of upgrading the module for a while and started to work on it, but some more urgent projects took a higher priority. The version on which I'm currently working will use grass 62 and modflow 2005, which was just released.
 The webpage pointed by Sören (www.valledemexico.ambitiouslemon.com/gwmodeling.html) has the r.gmtg module and a brief tutorial. A more detailed description is available on Computers and Geosciences 32(3): 339-351
 In case the webpage's still out longer I'll figure out a way to upload both the module and MODFLOW-96 (the version on my webpage was slightly modified).

So what model is actually used? Not MODFLOW, judging from your comments. 
I am eager to see more documentation!
