Abstract

The five electrode method of resistivity sounding (Barker, 1981) conventionally yields a set of smoothed apparent resistivity values corresponding to electrode spacing representing variation with depth beneath the central electrode. Wenner-a measurements utilising the four electrodes at either side of the five-electrode spread are averaged to foren the smoothed values and are differenced to foren offset measurements indicative of lateral resistivity variation. As electrode spacing is increased, the offset. Wenner measurements yield resistivity values in a triangular cross-section beneath the five -electrode array .
