Top panel: 2D slices of the 3D inverted bulk EC distribution and sensitivity for the laboratory column (scale S3) at selected time steps. The VWC sensor location is indicated by white dots and the white rectangles correspond to their volumes of investigation. Bottom panel: evolution of (a) VWC and (b) inverted bulk EC in the tailings during the artificial precipitation event and (c) petrophysical relationship between VWC and bulk EC in the bucket.
