Évaluation De L’hydraulique Pastorale Au Profit De L’élevage Camelin «contraintes Et Défis Au Bas-sahara» : Cas De La Région D’el Hadjira.

Résumé: the needs, the yield and the quality of the samples. Every year, dozens of new wells are built, dozens of wells are closed. The objective of this study is to give a diagnosis of the current state of pastoral hydraulics through an inventory of water wells, in the lower Algerian Sahara case of the El Hadjira area. The working method begins with visits and field trips to technical services for the collection of information and the collection of basic documents. 94 wells in the study area were chosen, spread over the two communes of El Allia and El Hadjira. Most wells or watering basins for camels have major problems; poor wells, outages, electricity problems, lack of maintenance, traditional wells, and fraud by other industrial sectors (E.N.A.G.0), the case of the Hassi s'bil N°2 well. The south-eastern area of El Hadjira is characterized by favorable topographic and hydro-geological conditions, the realization of new pastoral wells in this area is in favor of camelins. On the other hand, the south-western zone of El Hadjira (Oued N'SA) has unfavourable geological and hydro-geological conditions, allowing us to avoid the realization of pastoral wells in this area.
