Résumé
Recently converted to drip irrigation, the C3 district in the perimeter of Gharb Morocco is home to two irrigation modes operating simultaneously. During this transition phase, the on-farm drip equipment is not yet installed on all farms, some farmers still irrigating by sprinklers using either the old existing hydrants or the new farm outlets. This study has a double aim. firstly, is to assess the irrigation system performances under different operational conditions by means of hydraulic simulation models in COPAM and AKLA using relative pressure deficit and reliability as performance indicators. Secondly, is to enhance the service quality to conduct the on-farm irrigation in an appropriate way. Five scenarios were prepared according to the spatial-temporal evolution of the on-farm drip and sprinkler equipment also structural improvements were tested. Fields measurements and surveys were conducted to compare between experimental and simulation results . Different levels of pressure drop were noticed at some critical zones of the network. Reinforcing pipe size or increasing the total piezometric elevation at the pumping station showed satisfactory results.
