Transport Processes in Porous Media by Self-Potential Method

Figure 6

Comparison between SP values measured at different salt solution concentration (blue = 6.00 g L⁻¹, green = 1.00 g L⁻¹, and violet = 0.25 g L⁻¹), at three different positions of the column. The red lines indicate the arrival time of the saline front at the electrodes.
