ex15: Example 15--1D Transport: Kinetic Biodegradation, Cell Growth, and
Sorption
Description
A test problem for advective-dispersive-reactive transport was
developed by Tebes-Stevens and Valocchi (1997) and Tebes-Stevens and others
(1998). Although based on relatively simple speciation chemistry, the
solution to the problem demonstrates several interacting chemical processes
that are common to many environmental problems: bacterially mediated
degradation of an organic substrate; bacterial cell growth and decay; metal
sorption; and aqueous speciation, including metal-ligand complexation. In
this example, the test problem is solved with PHREEQC, which produces
results almost identical to those of Tebes-Stevens and Valocchi (1997) and
Tebes-Stevens and others (1998). The example can be run using the
phrRunString routine.
