The data were interpreted using a conventional partial curve-matching method to obtain initial model parameters, which were used in a computer program IXID to obtain final parameters. Aquifer parameters of longitudinal conductance and transmissivity were obtained using Dar-Zarouk parameters. The results of interpretation revealed four to five geoelectric layers. High transmissivity values are recorded at VES 3, 4, and 5 with high thicknesses, which imply that thick aquifer materials have higher transmissivity values than areas underlain by relatively thin aquifer materials. Such result is expected because transmissivity is a function of aquifer thickness.enAnjagwa, aquifer, geoelectric, isoresistivity, Schlumberger vertical electrical soundings, transmissivityArticle
