| dc.description.abstract | This study entitled ‘Application of Integrated Geophysical Techniques to Map Deep Groundwater Potential Zones and Geological Structures, South-West Akaki, South-East of Addis Ababa, Ethiopia’ was done using Vertical Electrical Sounding and Magnetic geophysical methods. The aims of the study are to investigate the deeper high potential groundwater saturated zones and linear geologic structural elements which dissect the study area and could possibly act as a hydraulic barrier that impedes or enhance the movement of the groundwater. Further, the work is aimed at determining the depth to water table and identification of drilling point through interpretation of the geophysical, geological and borehole data. Geophysical data have been measured, processed and interpreted in one and two dimensions using special software. The results of interpretation indicate that the study area composed of two aquifers, the first is the Upper Basalt aquifer which is slightly confined between alluvial deposits (upper) and Massive Basalt and Trachytes (lower) and the second is Lower Basalt aquifer which is confined by the Tarmaber Basalt. The depth of the upper aquifer is ranging from 40 to 70m while the depth of the lower aquifer is greater than 250m. The area is dissected by fault elements of NW–SE and NE–SW trend.
