Hydro-Geophysics
Applications
Hydro-geophysics
has been developing rapidly in order to aid hydrologists.
As water becomes an increasing concern, both natural and
artificial aquifers have had artificial recharge applied
for water storage. Many unknowns of water distribution occur
within these aquifer storage and recovery (ASR) projects.
Our work seeks to establish the geophysical methodology
for which to observe aquifer storage and recovery systems
for more efficient use. The reserch uses the Leyden
Lignite Mine as a field test site. Theoretical development
in joint method inversion and numerical modeling is carried
out for the 3-D problem.
| Goals |
| |
|
|
| |
1.
|
|
The distribution of water throughout the ASR process
using time-lapse geophysics |
| |
2.
|
|
The time-varying subsurface physical property distributions
due to the ASR process |
| |
3.
|
|
Building a hydrologic model based on these time-varying
physical property distributions |
| |
4.
|
|
And advancement of the overall use of multiple geohysical
methods to reduce uncertainty in hydrological characterization
|
| |
5.
|
|
Provide baseline methodology for the succesful monitoring
of water storage and recovery in subsurface reservoirs |
