|Title:||HYDROGEOLOGIE D’UN SYSTEME AQUIFERE EN ZONE SEMI-ARIDE.CAS DE LA REGION DE KHENCHELA (ALGERIE)|
|Abstract:||The hydrology of arid and semi-arid Algeria is a complex subject. Khenchela region, which is affected by chronic drought and climate always negative balance does not justify or clarify the existence of a groundwater recharge. Now this charge, even if limited, often exists in these arid regions where the climate can cause irregularity in some years a few exceptional rainfall events [1, 2, 3, 4]. Three aquifer systems are distinguished in the wilaya of Khenchela: Quaternary, Cretaceous and Miocene. There are four aquifers, one is superficial, it is heterogeneous aquifers and the rest are represented by the deep groundwater aquifer plains of collapse, the web of cracked limestone formations and the water inland. The depth of these aquifers ranges from 5 to 600 m. The total collected from all aquifer is 34 million m3/year . The main objective is to identify the aquifers in the region to establish a database on water training possibilities in the region of Khenchela.|
