ABSTRACT Electrical resistivity measurements at high resolution (1.5-cm electrode spacing) were performed to detect, from the soil surface, small cracks developing within the soil. We recorded a vertical electrical pseudo-section in a decimetric undisturbed homogenous soil block (silt loam) for different 11/11/2009 Electrical Resistivity Imaging for Detect… soil.scijournals.org/cgi/content/…/1319 1/17

DISCUSSION CONCLUSION REFERENCES TOP ABSTRACT INTRODUCTION Principle of Electrical. .. MATERIALS AND METHODS RESULTS DISCUSSION CONCLUSION REFERENCES artificial cracking stages. Because of the unusually reduced electrode spacing associated with an air-dried soil surface, a specific Cu/CuSO 4 electrode was designed for precision wet contact at given points. The apparent resistivity measurements of the pseudo-section and the interpreted data inverted by using the Res2Dinv software are discussed. The range of interpreted electrical resistivity associated with cracking is considerable, (from 168 to 2185 m) because the cracks are filled with air that is an infinitely resistant medium. Results showed that even small structures cause perceptible changes in resistivity that can be detected by the electrical resistivity method.
