Determination of cavities using electrical resistivity tomography

Contributions to Geophysics and Geodesy, 2012
Geophysical surveys for cavity detection are one of the most common nearsurface applications. The usage of resistivity methods is also very straightforward for the air-filled underground voids, which should have theoretically infinite resistivity in the ...
