Assessing groundwater potential could be aid by different geophysical methods. Electrical imaging techniques are used to investigate subsurface geology based on the resistivity in the earth's field resulting from the resistivity properties of the underlying rocks. To assess the groundwater potential Zone of Assosa town, electrical imaging methods were used. Geographically, Assosa town is bounded between 34°31'00''-34°33'24.2''E and 10°02'37.3''- 10°04'00''N that covers a total area of 610.8 Km2. The resistivity of rocks is extremely variable depending on the type of rock, the presence of conductive materials, salinity, and abundant pore spaces. The geology of the area contains a Precambrian deposit and is dominantly covered by granitic rocks. The hydrogeological units of the area include alluvial deposits, which show permeability, fractured, and weathered granite. 2D electrical imaging using the Schlumberger configuration array was conducted to assess the geo-electric properties of the subsurface to determine the apparent resistivity, thickness, and depth of the subsurface formation. Generally, the resistivity of the area increases downward, this reveals that the top part of the study area is saturated and highly fractured than the bottom part, which is below 50 m depth.
