Computation of the Field Apparent Resistivity of the Soil for Driven-rod Electrodes

Abstract

In this paper, analytical formulas for computation of the field apparent resistivity of the soil for driven-rod electrodes are presented. General four driven-rod electrode array configuration and its special cases: general symmetric, Schlumberger and Wenner driven-rod electrode array configurations are considered. For the Wenner four driven-rod electrode array configuration, the percent deviation of the field apparent resistivity computed using a formula valid for point electrodes was investigated.
