The code is based on previous work carried out at Delft
University of Technology, the University of Tuebingen
(Center for Applied Geoscience), the Contaminated Land
Assessment and Remediation Research Centre (University of
Edinburgh), and the University of Western Australia.
The most recent version of the code (v2.10)
incorporates MT3DMS (5.3) for the simulation of three-dimensional advective-dispersive
multi-component
transport and the geochemical model PHREEQC-2 (v2.17)
for the quantification of reactive processes. PHT3D uses
PHREEQC-2 databasefiles to define equilibrium and kinetic (e.g.,
biodegradation) reactions.
MT3DMS is based on MT3D, originally developed by Chunmiao Zheng
at S.S. Papadopulos
& Associates, Inc. and documented
for the United States Environmental Protection Agency. MT3DMS
is written by Chunmiao Zheng
and P. Patrick Wang with the iterative solver routine by Tsun-Zee
Mai.
Funding for MT3DMS development was provided, in part, by U.S. Army
Corpsof Engineers Waterways Experiment Station.
PHREEQC-2
is a computer program written in the C programming language that is
designed toperform a wide variety of low-temperature aqueous
geochemical calculations. PHREEQC-2 was developed by D.L. Parkhurst
as part of the Reaction-Transport Modeling
in Ground-Water Systems Project
at USGS and C.A.J. Appelo.
It is based on former versions of PHREEQC/PHREEQE by D.L. Parkhurst.
As the public-domain codes PHREEQC-2 and MT3DMS form the
core of the coupled model, the underlying work of D.L. Parkhurst,
C.A.J. Appelo, C. Zheng
and their co-workers is greatly acknowledged.
PHT3D has been incorporated into various GUIs and pre/post processing tools
PHT3D has been tested for benchmark problems from the
literature and applied successfully for a wide range of biogeochemical transport modelling
studies. Executables
of the code are available for Microsoft Windows and Linux
. A first MPI-based parallel version of PHT3D
v2.17 has been developed by AaronMcDonough (CSIRO Advanced Scientic
Computing Group). The MPI version has been improved for a better
load balancing in 2021 by Janek
Greskowiak (University of
Oldenburg, Germany), tested and applied on various HPC platforms and
multi-core machines. A MPI PHT3D executable is now also available
for Microsoft Windows (see
downloads).
