ESRI-SC RESEARCH CAPABILITIES
ESRI-SC's capabilities related to government and private sector sponsored environmental studies and services include integrating geology, hydrology, and geochemistry with advanced computer applications for characterization of groundwater and surface water systems, water quality assessment, prediction of flow and solute transport, state-of-the-art environmental geophysics, and advanced geographic information systems development.
Our applied research focuses on both site specific and regional scale projects that involve field, laboratory, and modeling activities.
Further, ESRI-SC has extensive capabilities and experience conducting watershed studies, analyzing conservation efforts and best management practices, and developing user-oriented software solutions to a wide variety of natural resource problems.
ESRI-SC undertakes research
projects in different fields:
via aquifer tests and single borehole tests is an area of growing
capability within the environmental program at ESRI-SC.
Computer-aided analyses of aquifer test data lead to understanding
the dynamics of groundwater flow in both porous and fractured
saturated media. This understanding facilitates prediction of
the behavior of groundwater systems in terms of flow and transport
Another key component of our environmental research is the
use of geophysical techniques to describe the geologic
framework of groundwater systems and to determine the extent
of groundwater contamination. ESRI-SC has in-depth
experience with geophysical methods such as 2D and 3D
high-resolution shallow reflection seismic, shallow refraction
seismic, interactive seismic interpretation, EM conductivity,
ground penetrating radar, geophysical log analysis and interpretation
modeling, and mapping, DC resistivity.
Our water resources research program focuses on nonpoint
source pollution assessments including mechanistic studies of
the mobilization and transport of agricultural chemicals.
ESRI-SC also has recently completed development of a coupled
simulation-optimization computer program for determining the optimum
size of off-stream reservoirs to be used for water supply
augmentation and water quality enhancement.
ESRI-SC's geographic information system (GIS) is used
for managing large spatially-oriented databases and modeling diverse
geographic data. In addition to pursuing contamination potential
modeling, wellhead protection area delineation, source water
protection, and facility siting studies, GIS is used to develop
large, diverse spatial databases.
Computer modeling of groundwater flow and solute transport also is a
significant part of our environmental research capability.
ESRI-SC maintains a wide array of hardware and software dedicated
to modeling. In addition to modeling applications we
are conducting research on advanced techniques of coupled simulation
and optimization for managing groundwater systems for
either water supply or environmental restoration.
ESRI-SC capability includes both analytical and
numerical modeling using recognized computer codes such as the US
Geological Survey code MODFLOW along with pre- and post-processing
software. We also have
experience in the application of geostatistical
techniques to the evaluation of heterogeneity and spatial
variability of flow and transport phenomena. ESRI-SC has
state-of-the-art 3D visualization capabilities to display the
results of field and model-derived data.
Structural analyses of rock fabrics and fracture systems provide data
essential for highly refined computer modeling of groundwater flow,
for geohazard susceptibility and risk assessment in
conjunction with GIS, and for other environmental applications of
