Résumé partiel
Egyptian irrigation system in the Nile valley and its Delta relies on main conveyor,secondary, and tertiary canals to supply water up to the farm level, wherein farmers usepumps to lift water for irrigation. This system is characterized by having a large numberof users with small land-holdings. Also residential areas around tertiary canals orwasteful irrigation practises at the head of the tertiary canal leave users at the tail end ofthe canal with inadequate water. This system results in inequity in water distributionand high pumping costs for individual farmers. The Irrigation Improvement Project (IIP)is a state - of- the- art project in terms of the approach followed in involving the WaterUsers Association in the operation and maintenance (O&M) of the physical structures.But irrigation performance even though it became better than in the traditional state stillneeds to be improved particularly because of the insufficient participation of water usersin the technical process (planning, surveying, design, and construction) of the tertiarysystem development.. A combination of structural and non-structural measures can helpto improve the performance of irrigation system and its sustainability.This research illustrates a hydraulic design process using FlowMaster/Haestad softwarebased on the water users’ participation in the technical process of irrigation systemimprovement and also emphasizes on integration among different water users’ levels toimprove the performance of irrigation system. Indicators of system performance are alsodiscussed. These indicators comprise of : (1) reliability, which is a measure ofconfidence in the irrigation system to deliver water at the scheduled time and in rightamount ; (2) adequacy, which is a measure for supply of the required amount of waterfor optimum crop growth ; and (3) equity which is a measure for all the users of thesystem ensuring a fair share in water distribution.Findings indicate that effective water users’ participation in the technical process, wouldincrease the irrigation performance.
