Contributions a l'étude géologiques et hydrodynamiques du Complexe Terminal de la région de N'GOUSSA

Abstract

This study proposes a geological and hydrodynamic contribution of coverage of Mio- Pliocene age in the region of N'GOUSSA the wilaya of Ouargla. The surface of N'GOUSSA is 907 km2. It contains an aquifer of sand detrital deposits of the Terminal Complex (CT). This study deals with the natural context of the N'GOUSSA region in general and the Lahoua area in particular, before dwelling on the lithology and the longterm pumping tests of the aquifer. Then, the results of the various investigations using an interdisciplinary approach (lithological, pumping test, hydrogeological) and solutions of exploitations of the deep water table are proposed for water supply of agricultural in zone of agriculture of N 'Goussa
