Abstract


Thirteen Vertical Electrical Soundings using Schlumberger configuration with a maximum current electrode separation of 500m was carried out in Owhelogbo to determine the aquifer parameters. The data obtained were analysed first by curve matching before computer iteration to obtain the model parameters in terms of resistivity, thickness and lithology of the various layers. The Dar-Zarrouk parameters were used to obtain the hydraulic conductivity, K from aquifer conductivity σ and longitudinal conductance S. The hydraulic conductivity, Kσ values and the transmissivity of the aquifer layers were obtained for the various locations. VEV 4 and VES 2 have the highest and lowest transmissivity of 330.0m2/day and 140.0m2/day respectively.
