Abstract
An alternative approach was developed for evaluating the hydraulic conductivity (K) and the transmissivity (T) of an aquifer. The vertical electrical sounding (VES) measurements and fuzzy techniques (Takagi-Sugeno fuzzy model) are the base of this approach. This approach requires the VES measurements in some points, where available water samples exist to tune fuzzy system with fitting capability, to evaluate the hydraulic parameters. The tuned fuzzy system was used thereafter to extrapolate those parameters, even in VES points where no water samples are available. The Khanasser valley, Northern Syria was taken as a case study to apply the proposed approach. The comparison between the hydraulic parameters values obtained by the proposed approach and those of real pumping test shows an acceptable agreement between them, that attests to the viability of the new proposed technique for characterizing the hydraulic parameters of the aquifers in similar arid and semi arid regions.
