Surface and borehole geophysics methods are utilised for delineation of various phenomena including; profiling of bedrock topography and structure, mapping of the water table, fracture systems, permeability of aquifers, salt water - fresh water boundaries, groundwater contamination, perched groundwater, confining layers, and migration pathways. The primary motivation for using geophysics as a tool in resource exploration and aquifer management is to target areas for detailed investigation and/or as follow up to conventional SI techniques, for example to interpolate between boreholes.
SURFACE geophysical methods used include; seismic refraction and reflection, ground penetrating radar, electromagnetic conductivity profiling / sounding and imaging using the new Strataghem, 2D resistivity imaging, resistivity sounding, electrokinetic sounding (EKS), microgravity, magnetics, self potential and radon prospecting. BOREHOLE geophysical methods used include; crosshole seismics, seismic tomography, and wireline logging.
