ABSTRACT

ABSTRACT: An integrated study was carried out to investigate the subsurface geological conditions in a hard rock environment, with the aim to identify groundwater potential zones. The study considered the use of remote sensing, geo-electrical methods and nuclear magnetic resonance sounding techniques (NMRS). Remote sensing was used to identify lineaments which were extracted from the satellite images by directional filtering of the image. Resistivity profiles and NMRS were used to locate the lineaments more precisely on the ground. The identification of geomorphological significance of each mapped lineament has enabled the explanation of the relationship between lineament distribution and groundwater in fractured rocks. The study made it possible to select localised sites for the drilling of successful boreholes, after taking into account the hydrogeological and climatic conditions of the area. The results of this study, as tested in the Moroccan Anti-Atlas chain, show the importance of using an integrated approach for siting boreholes in hard rock terrain in a semi-arid climate.
