Electrical resistivity imaging geophysical surveys (also known as resistivity tomography, ERI or ERT) measure the resistivity properties of the sub-surface by assessing the potential drops between electrodes in a variety of configurations, depending upon the type of geophysical survey data required. Electrical ...

Geophysical surveys, which use geoelectrical methods base on the variation of electrical parameters of the soil. To understand the phenomena in ground-rock medium, in which electric current flows, it must be realized that such substrate resists while electric current flows through it. According to Ohm's Law, resistance R is directly proportional to applied voltage U and inversely proportional to ...

The use of geophysics has become increasingly beneficial to archaeological surveys. A geophysical survey should not be used to replace an in-depth archeological survey conducted by a qualified professional archaeologist. Instead, it should be used as one of many tools that can be applied to the investigation. Geophysics can be used to provide either a general site overview or a higher resolution ...

The investigation of potential karst (sinkhole) activity at residential or commercial properties or undeveloped land is a multi-disciplinary process in which geophysics plays a critical role. Subsurface geology in karst environments is very complex and is often masked at the surface. Properly selected and applied geophysical tools will provide a 2 or 3 dimensional perspective of subsurface ...
