Top panel: inversion mesh, 2D inverted bulk EC distribution and sensitivity in the experimental field cover at pilot scale (scale S5) for a representative time step. The VWC sensors are indicated by white dots and electrodes correspond to red dots. Bottom panel: evolution of (a) precipitations, (b) VWC and (c) inverted bulk EC in the tailings from May to November 2021 and (d) relationship between VWC and bulk EC in the experimental CCBE cover at pilot scale.
