RELATION FRACTURATION-MORPHOLOGIE IMPLICATIONS HYDROGEOLOGIQUES. EXEMPLE DES CALCAIRES FISSURES DE LA REGION DE CHERIA (NE ALGERIEN)

Abstract

The area of Chéria is located at Algerian, with 45 kilometers in the South-west of the town of Tébessa. The area catchment to study extends on a surface from 720 km2, shelters more than 74300 inhabitants and characterized by a semi-arid climate.The area is formed primarily by limestones of Maestrichtien and Eocene which are fissured karstic and which constitute the aquiferous potential of the area. This study tries to confirm the relations between morphology and the fracturing in limestones and to confront them with the flows of the tablecloths of the latter.
