All ofmaterial in the earth has specific restivity value, so that it can be measured with using Geoelectrical equipment. Geoelectrical method uses electric resistivity variation based on the measurement ofpotentials differentiation caused ofthe current injected into the earth. Sofar the value ofmaterial resistivity still known in general, like sand: 10 -5000 ohm.m, sand saturated: 1 -1750 o…
