The predictive capability of groundwater flow models is frequently restricted by insufficient
characterisation of a typically heterogeneous and anisotropic subsurface. Trace levels of …

Azimuthal resistivity surveys are often applied to complement hydrological information or to
improve the location of observation boreholes in pump tests. Symmetric electrode …

Within fractured rock, the irregular and often unpredictable distribution and geometry of
hydraulically conductive fractures produces large spatial variations in bore yield and …

The potential for the geophysical characterization of fractured rock bulk anisotropy using
azimuthal self potential gradient (ASPG) method was investigated at four fractured rock field …

Many rocks and layered/fractured sequences have a clearly expressed electrical anisotropy
although it is rare in practice to incorporate anisotropy into resistivity inversion. In this …

Many rocks possess electrical properties with a clearly expressed anisotropy. The
anisotropic character of the rocks is often overlooked in forming the Fréchet derivatives or …

Fractured sedimentary bedrock rivers exhibit complicated flow patterns controlled by the
geometry, extent and connectivity of fractures and dissolution-enhanced conduits. In a …

The pneumatic fracturing technique is used to enhance the permeability and porosity of tight
unconsolidated soils (eg clays), thereby improving the effectiveness of remediation …

The coupling between a horizontal loop EM (HLEM) system and a buried object, eg, a
buried pipe, is well-established; the response depends on the orientation of the transmitter …

The use of transient controlled-source electromagnetic prospecting to detect buried, steeply
dipping foliation in metamorphic rocks is illustrated with data acquired over the Precambrian …
