%X The lack of knowledge about fracture systems in Tanda region has led to an approximative establishment of drilling and so a difficult access to groundwater. Thus, a multidisciplinary approach including satellite imagery and electrical resistivity method was conducted with the main objective to locate productive fractures of water in the study area. Indeed, 195-54, 195-55, 196-54, and 196-55 scenes of Landsat 7 ETM+ satellite images were used. Also, sixty-two (62) vertical electrical soundings (VES) of the Schlumberger configuration and hundred twenty-nine (129) electrical trailing (ET) were performed with a resistivity-meter SYSCAL Pro. Thanks to different treatments applied to satellite images, structural lineaments have been extracted whose main directions are N00-10 (N-S), N90-100 (E-W), N70-80 and N100-110. The interpretation of electrical trailing data made it possible to validate the lineament map by the determination of the fracturing directions. Those are NW-SE, N-S, NE-SW and to some extent E-W. The result of the electrical sounding data showed the presence of three geoelectric layers comprising firstly cuirass and lateritic clays and possibly topsoil, secondly sands and/or clay sandstone and firdly either granites or sandstones or schists. The second geoelectrical layer corresponds to the potential aquifer because of its relatively low electrical resistivity values (13 ¦¸¡¤m to 180 or 240 ¦¸¡¤m). In addition, drillings established at the right of these geological structures provided an average water yield of 4.22 m3¡¤h-1, sufficient for rural hydraulic. Moreover, these results made it possible to obtain a correlation between drilling productivity and the major directions of fracturing. This indicates that the most productive directions are in order of importance NE-SW, NW-SE, E-W and finally N-S. They also correspond to the major fracturing directions of Tanda region. These results are encouraging and contribute to a better implementation of future drilling in this region.
