<p>HBGC123D is a computer code for the simulation of coupled
non-isothermal hydrologic transport and biogeochemical kinetic and/or
equilibrium reactions in variably saturated media.
<br>
This page gives you access to Release Version 1.0 of this code.
<br>
<a href="/index.shtml">Release Version 1.1</a> is now available.</p>
<p>HBGC123D is an extended version of the 2D code HydroBioGeoChem
developed by Drs. Karen Salvage and George (G.-T.) Yeh at Penn State University
(Yeh et al., 1998).
It was developed as part of a <a href="http://www.doe.gov/"

of Coupled Processes on the Fate and Transport of Industrial Mixed Waste
Plumes in Structured Media</b></a>.</p>
