PHREEQC does not solve the unsaturated zone equations for flow and
transport. Flow can be reversed, but it must be manually specified.
I don't know of any publicly available codes for treating unsaturated
transport with reactions. Our Dept of Energy National labs have such codes
as well as the Waterloo University in Canada, but I don't think they are
available for distribution.

Dear David,
I would like to model vertical transport in 2-m soil layer with reactions,
including water evaporation, carbonate precipitation-dissolution etc.
Actually, water extraction should change vertical flow velocity. Is it
possible to use PHREEQC for such problems? Do you know software treating
the unsaturated transport with reactions?
Thank you for your help.
Sincerely,
Michael Zilberbrand
