Résumé : | In order to point out the effects of changing the delivery schedules in a pressurized irrigation system on the supplied volumes and on the hydraulic performances, discharge withdrawals have been continuously measured from 1991 to 1995 in a Southern Italy irrigation district and in a representative sector in particular. The daily continuous specific discharges have been calculated and compared. The analysis showed that, during periods of limited availability of water, when on demand delivery schedule is changed to restricted frequency demand, no reduction in water supply is obtained and only a modification of the upstream demand hydrograph is recorded. Furthermore, it is observed that during periods of water restriction the hydraulic performance of the system is reduced and considerably affects the on-farm system operation |
