> Currently, I am working on modeling geochemistry for the acid sulfate soil in Thailand and I am intersted in using the PHREEQC inverse modeling to come up with amount of mass transfer between an upper (upgradient) and a lower (downgradient) locations. they both are in the same flowpath as teh water infiltrates downward. However, both locations are in the unsat zone. I am wondering if PHREEQC will be applicable in this case. You should be able to use inverse modeling if the downgradient water evolves from the upgradient water. It is also possible to consider the evolution of rain to each of the waters, if this is the basic situation you are considering.
