Electrical Resistivity Tomography, an Assessment Tool for Water Resource: Case Study of Al-Aroub Basin, West Bank, Palestine

A. Sirhan, M. Hamidi and P. Andrieux

Abstract:
This study aimed to characterize the nature of the shallow subsurface infiltration areas (3-18 m) and to understand the link between water storage transfer and the characteristics of the chalky formation, usually considered as aquitard (non acquifer) by applying the Electrical Resistivity Tomoraphy (ERT) technique. A multi-electrode geo-electrical survey was carried out at AL-Aroub area, West Bank, Palestine to map the electrical resistivity distribution. Electrical Resistivity Tomography (ERT) method is based on the measurements of electrical resistivity along a profile, where a series of electrodes are regularly placed. The interpretation of two dimensional (2D) pseudo-sections showed the existence of a continuous dominated moderate layer (90<ρa<130 Ωm) accompanied with an upper clayey layers (<30 Ωm). Meanwhile, the heterogeneity of the shallow subsurface layers is evident; the later result permits to explain the groundwater circulation within the fractures existed in the chalky geological formations. These results are highly correlated with the existed dug wells located at the study area.
