Etude des performances et fiabilités des différents types de goutteurs en irrigation localisée par les eaux usées épurées

Abstract

While being recognised as one of the most water efficient irrigation techniques, with an efficiency coefficient close to 95%, localised irrigation has not obtained an appropriate position in irrigation schemes in arid and semi-arid countries such as Algeria. The main reasons for this are the high cost and the high degree of technicality that is required from the farmer for operating such systems.This work intends to study the reliability of drippers were performed on the irrigation systems. The operation stability of the considered elements over time is a key indicator of the quality of the irrigation system. The obtained results demonstrate that a better design of system components, their fabrication and the quality of the used water are the main element to achieve a high reliability of such a system.
