Comparison of three arrays in time-lapse ERT: Simulation of a leachate injection experiment

Abstract

Leachate recirculation in bioreactor needs a careful optimization of water content and thus, the knowledge of the leachate plume geometry. Time-lapse Electrical Resistivity Tomography (ERT) is widely use for this purpose. However, in some situations, artefacts of ERT imaging can occur with classical inversion parameters. Using numerical modelling (simulating a 2D infiltration experiment) and standard inversion parameters, this study shows that artefacts may occur using common symmetrical electro (...)
