GEOINNOVATION explores geology, geotechnics, and the environment. We connect field observations, geophysical investigation, and numerical modeling to understand ground conditions and support practical decisions.
ScrollA small company that digs deep
GEOINNOVATION is a privately held research company based in Daegu, Korea. Our work spans engineering geology, geotechnical and geoenvironmental engineering, geophysics, and hydrogeology. We connect field investigations with numerical modeling and research on inverse problems and uncertainty, and develop practical software for data analysis and interpretation.

Research
The questions we work on, ordered from the surface downward.
-
Geotechnical engineering
We study soil and rock behavior, slope stability, and the influence of groundwater on ground conditions. Field investigations, geophysical surveys, and numerical modeling support the assessment of geotechnical conditions and risks.
-
Groundwater recharge estimation
We estimate recharge from water-table fluctuation (WTF) records and report how much each estimate can be trusted. Both recession-curve analysis and Kalman-filter methods are covered.
-
Geophysical exploration
We investigate subsurface structures and properties using electrical resistivity, seismic, electromagnetic, ground-penetrating radar (GPR), gravity, and magnetic methods. Our research integrates survey design, data processing, forward modeling, and inversion to support geological, geotechnical, groundwater, and environmental investigations.
-
Uncertainty and information theory
Using Fisher information and the Cramér–Rao bound, we establish the theoretical limits of recharge and resistivity estimates, and use that framework to decide whether more data or a different model is needed.
-
Managed aquifer recharge (MAR) pre-assessment
We are developing a site-selection and pre-assessment methodology for managed aquifer recharge and validating it against field data.
From research to tools
Tools for basin-scale recharge analysis, groundwater time-series modeling, and electrical resistivity inversion.
