The earth dam of Salhab, built in 1993 and located in northern-west of Syria consists of two separated embankments. The main one extends east-west along a distance of 895m with 14.5m height, while the second embankment towards northwest-southeast over a distance of 510 m and 11 m of height.
Water flow was observed from the piezometric wells (Pz). In the current case study, the Electrical Resistivity Tomography (ERT) and Self Potential methods were used to characterize the possible zones of water leakage through mapping in detail the subsurface structures of the geological formations underneath and behind the dam body. A number of electrical resistivity tomography profiles combined with SP measurements have been carried out (ERT-P) …more
