Abstract: Hydrogeophysical studies of some selected towns in Imo River Basin were carried out to determine the aquifer hydraulic characteristics and evaluate the groundwater potential of the study area. A total of thirty-eight (38) Vertical Electrical Sounding (VES) in fifteen (15) towns in Imo River Basin were conducted to obtain the aquifer resistivity data. The results of the qualitative interpretation of the VES data indicate that 75% of the field curves at the boundary of the aquifers terminated as K-shaped and Q-shaped type curves.
