Relationship between soil moisture and inverted resistivity for Sensor 4 at the base of the downstream slope. Initially, soil moisture was stable (7.8-8%), while resistivity varied (136.9 to 831.4 ohm·m). After 04/13 20:00 PM, moisture increased due to the saturation front, leading to decreased resistivity as saturation stabilized above 25%. By 04/19 8:00 AM, moisture dropped to about 9.5%, indicating stabilized groundwater levels and further reduced resistivity.
