This studyexamined the hydrological modeling of aquifers and their ground water potentialsfor the purposes of water resources planning and management. This was done usingthe electrical resistivity method employing the schlumberger electrode configurationat randomly selected stations to obtain the thicknesses and resistivities of eachlayer and depth to the presumably conglomeratic sand stone and its resistivity.Findings showed that the top soil layer resistivity values vary from 59.3 to 248.4ohm-m and thickness of 0.6 to 3.9 m. The second layer has resistivity values rangingfrom 45.0 to 743.5 ohm-m and a thickness range of 1.5 to 13.8 m. The wet sand ischaracterized by resistivity values ranging from 144.8 to 1930.2 ohm-m and a thicknessrange of 3.8 to 65.8 m. The conglomeratic sand-sand stone has resistivity valuesranging from 55.8 to 7719.8 ohm-m. The depth to this bottom layer varies from 6.6to 89.5 m. Findings indicate that the entire profile is a sedimentary formationrepresented by lithological units of sand and clayey sand which make for a goodgroundwater potentials. However, the groundwater potential zones of the study areain terms of transmisivity revealed four distinct classes representing -very good-Mgbuosimini, Rumuigbo, Okporo, Rumuomasi and Rumuodara -good- Alakahia, Rumuodomaya,Oginigba and Rumuola -moderate- Aluu, Rumuekeni, Rumuokoro, Rumuobiakani andRumueme, and -low- Ogbogoro, Ozuoba, Akpajio, Elelenwo, Eliozu, Rumuepirikon,Rumuokwuta, Rumuebekwe and Rumurolu groundwater potential in the area. Well loggingshould therefore be incorporated in borehole development process for safe and sustainableyield of groundwater in Obio-Akpor.
