 note = {Self-potential exploration is a simple technique for observing electric potential in the ground. Non-polarization type electrodes using lead - lead chloride solution and a high input impedance voltage meter were used to measure selfpotential in this study. Streaming potential is one origin of self-potential related to soil water movement. Generation of streaming potential was verified by an infiltration test with a sand column. Field observations of self-potential were
conducted at a slope landslide before and after groundwater control works were completed. Self-potential values decreased around drainage pipes after groundwater control work. Groundwater level was lowered by groundwater control works and induced water movement toward the drainage pipes at depths of 5 and 10 meters below the ground surface. The reason for the decrease in self-potential around drainage pipes is thought to be caused by downward
water seepage.},
