Thanks Markus,
right now these two modules are not documented and in a very early functional state, like the underlying gpde lib. 
But i will submit in the next weeks (2-4) a major update of the gpde lib and the groundwater flow modules. 
This will include a much better documentation, 
exact null value support for 2d and 3d data arrays, array io functions, gradient calculation, more unit tests and 
a new solute transport module for transport calculation of groundwater pollution in porous media 2d/3d. 

AFAIK, there was a module to combine modflow with grass
for groundwater calculation:
but this link is not reachable. :(

Best regards
