Geophysical Science in Oklahoma and Texas
Geophysical techniques used by the Oklahoma-Texas Water Science Center (OTWSC) provide a relatively quick and inexpensive means to gain insights into how groundwater systems work and the occurrence and distribution of certain contaminants. These techniques are an important tool for scientific investigations, environmental planning, and resource management. Visit the links below for more information on our data and science.
GEOPHYSICAL SCIENCE CAPABILITIES
OTWSC has expertise in a wide variety of geophysical science applications, including, but not limited to:
- Surface-water/groundwater interaction
- Using passive near-surface and frequency-domain electromagnetic induction methods profiling to identify surface-water and groundwater interaction.
- Using time-domain electromagnetic sounding (TDEM) and seismic refraction tomography (SRT) geophysical methods for mapping the contacts between aquifers or geologic units.
- Borehole Geophysics
- Calculating and analyzing hydraulic properties
- Processing and analyzing acoustic properties
- Developing conceptual hydrogeologic models
- Delineating freshwater/saline water transition zones
- Surface Geophysics
- Determining leakage potential along streams and canals
- Developing near-surface zone fractures
- Characterizing hydrostratigraphy
- Detecting near-surface fractures and voids
