A remote sensing technique that monitors the electrical resistance of soils in a restricted volume near the surface of an archaeological site; buried walls or features can be detected by changes in the amount of resistance registered by the resistivity meter.
Surface Resistivity and Surface Resistance Measurements Using a Concentric Ring Probe Technique where the radius r varies from R1 to R2. It is important to remember that when testing the sur-face resistivity (or resistance) of any material, it is assumed that all the currents ï¬ow between elec-trodes along the surface and do not penetrate into
