Integration of ground geophysical methods to characterize near‐surface aquifer zones within an active mine

Near Surface Geophysics, Volume 22, Issue 5, Page 521-538, October 2024.
Abstract Understanding near‐surface groundwater storage, flow patterns, surface and groundwater interactions in mining areas can assist in making mining more efficient and profitable. This is especially important in opencast mines affected by water inflows that may negatively affect production and increase mining costs. We map and characterize the near‐

Slope failure remediation using constrained horizontal‐to‐vertical spectral ratio inversion techniques

Geophysical Prospecting, Volume 72, Issue 8, Page 3157-3167, October 2024.
Abstract Slope failure rates may be exacerbated by increased precipitation patterns associated with climate change. Such events are extremely disruptive for local communities affected. Rapid engineering remediation solutions generally require immediate site characterization, including information on depth to intact bedrock and groundwater conditions ...

Hydro‐Mechanical Characterization of a Fractured Aquifer Using Groundwater Level Tidal Analysis: Effect of Pore Pressure and Seismic Dynamic Shear Stresses on Permeability Variations

Journal of Geophysical Research: Solid Earth, Volume 129, Issue 8, August 2024.
Abstract Groundwater level tidal analysis is a powerful technique to monitor aquifer's permeability and hence its change over time. Earthquakes are known to affect aquifer's properties, in their vicinity through static stress changes but also further away through dynamic stresses.
