Abstract
Tunisia is enriched by many natural resources (natural water and geothermal water) that are located along the South to the North. This paper aims mainly to evaluate the resources water potential. The available remote sensing images for two typical examples (SE Jeffara basin and Utique basin) are analyzed and many seismic profiles are interpreted to delineate the surface and subsurface structures.
 The 3-D structures of Mio-Plio-Quaternary and Upper Cretaceous aquifers in South-East of Jeffara basin show an important reservoirs of water resources. The Upper Cretaceous aquifer "Complexe Terminal" is one of the most typical examples of exploitation features in hydrogeological research. It is formed by fractured limestones.
 The 3D-structure of Utique basin shows an important variation of thickness of Mio-Plio-Quaternary and Triassic series. The Mio-Plio-Quaternary series is formed by sand, clays and gypsum. The Triassic series is considered typical example for research the hydrogeological and hydrothermal water in Tunisia, especially in the North. In the subsurface, the triassic aquifer of Utique regions is formed by carbonates series. The hot spring in Utique basin is directly related to the Triassic dolostones which are extensively fractured [1].
 A geophysical survey was undertaken for groundwater in Tunisia. The interpretation of seismic reflection sections and petroleum wells allowed to precise the geometry in subsurface structure.

Summary
Tunisia is situated in the north of Africa plate. The northern Africa is bounded by an Alpine-type orogen resulting from the subduction and closure of the Tethyan Ocean and from the interaction between the European and African plates [2] and [3]. In the north of Africa is situated the Maghrebian domain. Tunisia is considered to be one of the countries least well-endowed with water resources in the Mediterranean basin. It is characterized by a semi-arid climate with mild, dry summers, wet winters and warm. Pressure on fresh water demand is increasing as a result of demographic increase, agricultural water use and the development of the industry and tourism sectors. These conditions forced Tunisian authorities and policy makers to encourage for new research for potential resources water
