What is mean for Electrical resistivity imaging?
Electrical resistivity imaging is a multi-electrode profiling technique that records hundreds of subsurface data points which are used to produce a colored two-dimensional cross section of the earth. Some typical examples are listed below.
Electrical resistivity imaging (ERI)-also known as electrical resistivity tomography (ERT)-is a geophysical technique used to create an image of a specific portion of the Earth's subsurface. It is created through the use of automated geophysical instruments that gather thousands of resistivity measurements via an electrode cable and multiple electrodes.
What is application of Geophysical resistivity imaging?
1. Bedrock fracture zones
2. Fault zones
3. Delineating tunnels and cavernous zones
4. Contamination plumes
5. Characterizing landfills
6. Water table determination
7. Archeological investigations
More instruction for Resistivity geophysical surveys
Resistivity geophysical surveys measure variations in the electrical resistivity of the ground, by applying small electric currents across arrays of ground electrodes. The survey data is processed to produce graphic depth sections of the thickness and resistivity of subsurface electrical layers. The resistivity sections are correlated with ground interfaces such as soil and fill layers or soil-bedrock interfaces, to provide engineers with detailed information on subsurface ground conditions
