The self-potential method is a geophysical method based on the natural occurrences of electrical fields on the Earth's surface. Self-potential survey is very useful in localizing, quantifying groundwater flows and imaging of waterlogged areas in El-Obour City, NE of Cairo, Egypt. The waterlogged areas at El-Obour City are dominant phenomena with hazard environmental impact originated from seepages of buried domestic, sewage and irrigation pipeline systems within the heavily populated city in low topography areas.
The results of interpretation have shown that the more polarizing area is found at the southeastern part due to increase the effect of subterraneous water accumulation with higher negativity of self-potential values for wider electrode spacing (20 m) that is responsible for effects coming from deeper equivalent depths
