Abstract

Soil Electrical Resistivity (SER) is being used to assist in subsurface modeling of hydrologic flows. In SER an artificially generated electric current is supplied to the soil and the resulting potential differences are measured. The patterns in potential differences provide information on the form of subsurface heterogeneities and these heterogeneities in electrical resistivity are considered as a proxy for the variability of soil physical and chemical properties. We have an Advance Geosciences (AGI Inc, Austin, TX) R8 SuperSting for resistivity measurement. Imaging is being done in 2D transects of 56 probes installed at the surface. Given that SER are images are be remeasured at the same location changes with time are inferred to reflect changes in moisture.
