To infer the hydrogeological features of an area about 300 square km wide in the Alpine Nappe, we present a 3D geological model of a zone in Alpine Nappe in NE Algeria (between the "Wilaya" of Batna and "Wilaya" of Biskra), where field mapping is nowadays impossible. Therefore a preliminary geological model was built based on previous maps (both geological and hydrogeological), subsurface data (well-logs), photo-interpretation and remote sensing. The area is characterized by the superposition of several folding events from Middle Eocene to Pleistocene that strongly influence the geometry of the main aquifers.
