rafleiðnimælingu
Rafleiðnimæling is a geophysical exploration method used to determine the electrical resistivity of the subsurface. This technique relies on the principle that different geological materials have varying abilities to conduct electricity. By injecting electrical current into the ground through one or more electrodes and measuring the resulting potential difference at other electrodes, the resistivity distribution can be inferred.
The fundamental equation governing this process is Ohm's Law, adapted for distributed current injection and potential
The interpretation of resistivity data involves inverting the measured apparent resistivities to produce a model of
Rafleiðnimæling is widely applied in hydrogeology for groundwater exploration and mapping aquifer boundaries, in mining for
