Inverse slope method for hydro-geophysical characterization of the Neogene basaltic aquifer in Jbab area, Southern Syria

Schlumberger configuration with a maximum current electrode separation of 2000 m has been used for measuring eighteen vertical electrical soundings (VES) in basaltic Jbab area, Southern Syria. Those measured VES data are interpreted herein by the inverse slope method (ISM), to obtain the thickness and resistivity parameters of the different lithological layers penetrated by the electrical current in study area. The consistency and validation of the ISM results are decided through the application of Nash criteria, where satisfactory models are obtained for the basalt Neogene aquifer in the research area. According to the ISM approach, the basaltic aquifer is well characterized through determining its geo-hydrodynamics parameters. Those parameters are thickness, resistivity, hydraulic conductivity, transmissivity, formation factor, porosity, fractured porosity, permeability, and tortuosity. Vue the encouraging ISM results obtained in this case study, it is therefore recommended to apply the ISM approach worldwide to characterize similar challenging aquifer basaltic environments.
