  abstract = {{L}eachate recirculation is a key process in the operation of municipal waste landfills as bioreactors. {I}t aims at increasing the moisture content to optimise the biodegradation. {B}ecause waste is a very heterogeneous and anisotropic porous media, the geometry of the leachate plume recirculation is difficult to delineate from the surface at the scale of the bioreactor site. {I}n this study, 3-{D} time-lapse electrical resistivity tomography ({ERT}) was used to obtain useful information for understanding leachate recirculation hydrodynamics. {T}he {ERT} inversion methodology and the electrode arrays were optimised using numerical modelling simulating a 3-{D} leachate injection scenario. {T}ime-lapse {ERT} was subsequently applied at the field scale during an experimental injection. {W}e compared {ERT} images with injected volumes to evaluate the sensitivity of time-lapse {ERT} to delineate the plume migration. {T}he results show that time-lapse {ERT} can accomplish the following: (i) accurately locate the injection plume, delineating its depth and lateral extension; (ii) be used to estimate some hydraulic properties of waste.},
