Sensitivity Plots using COMSOL Multiphysics®: A Tool for Optimizing Geophysical Field Survey
Electrical resistivity surveys have been used for many decades in hydro geological, mining and geotechnical investigations. Various types of electrode combinations have been tested. But different array gives different type of response over same sub-surface feature. Response of different array is determined by sensitivity of that array. The sensitivity function of an array describes about the degree to which a small change in the resistivity of a section of the subsurface can influence the potential measured by the particular array. The sensitivity function has been computed using electric current interface of AC/DC module of COMSOL Multiphysics®. The sensitivity plots generated through COMSOL Multiphysics helps in planning in field survey which is an integral part of geological interpretation.
