AHPCRC Ground Water Modeling
Groundwater and Contaminant Transport Modeling
Investigators
Di-Wen Chen and B. Vona - Clark Atlanta University /Army HPC Research Center
Objective
This project is part of an ongoing
study of groundwater flow and contaminant transport models and their
enhancement with analytical software such as Geographic Information system
(GIS) in order to design more effective prediction and remediation procedures
for groundwater contamination. The project is a collaborative effort named
Groundwater Flow and Solute Transport Modeling for Assessment and Producing
at A Superfund Site in Florida, and involves researchers from CAU,
Environmental Protection Agency (EPA) Athens. D.W. Chen spent three months at
in EPA Research Laboratory at Athens. B. Vona visited EPA Athens occasionally
during this period.
Relevance
The successful completion of the project will result in a
better assessment of contaminant transport at a specific site, real life
application and testing of the DOD Groundwater Modeling System (GMS), and a
deeper insight into effective strategies for linking groundwater models and
GIS. The overall result will be the design of better, more comprehensive
assessment and analytic tools.
Methodology
The modeling work involves data
collection, data analysis and visualization, model calibration and routine
simulation. An important issue in the application of mathematical models to
describe or predict the fate of solutes in soil and groundwater system is
providing the necessary data to support the spatial, temporal, and
hydrogeologic model parameter requirements. A management tool is required
that allows the model to interact with various needed databases, cope with
numerous database management issues, efficiently achieve model
parametrization and provide visualization of model input/output. The
three-dimensional Groundwater Modeling System (GMS) just developed by the
U.S. Army Corps of Engineers and the U.S. Environmental Protection Agency
contains a state-of-the-art flow and solute transport model, a graphical user
interface for data manipulation and data analysis GIS link, and model
input/output visualization technology.
