ABSTRACT: In the A?r massif, and more particularly in the Iférouane
area, the basement is flush. Thus, the essential of water resources is
contained in the discontinuous aquifers of basement. Indeed, the weathered and
cracked basement is an excellent reservoir of groundwater. The objective of
this study is to determine the areas favorable to establishment of productive
drilling in the village of Ebourkoum. A methodological approach based on the
combination of remote sensing and geophysics methods was implemented. The
fracturing map developed highlighted three main accidents of directions N0° - N10°, N30° - N50° and N130° - N140° in
the said locality. The geophysical investigation mainly electrical prospecting
has allowed
to locate structures with high hydraulic potential below alluvium and
alterites. Subsequently, drilling will be carried out in the areas retained.
