A high resolution, cross-borehole, 3D electrical resistivity tomography (ERT) study of solute
transport was conducted in a large experimental tank. ERT voxels comprising the time
sequence of electrical images were converted into a 3D array of ERT estimated fluid
conductivity breakthrough curves and compared with direct measurements of fluid
conductivity breakthrough made in wells. The 3D ERT images of solute transport behaviour
were also compared with predictions based on a 3D finite-element, coupled flow and …
