Abstract

This study was conducted to evaluate the performance of the classic sprinkler irrigation system and identify the exploitation challenges. The assessment included the measurement of the uniformity coefficient of Christinean (CU), Distribution Uniformity (DU), potential effeceincy of the low quarter (PELQ), and application effeciency of low quarter (AELQ). The average wind drift and evaporation losses was 19 and 16 percent in selected farms in Isfahan and Fars provinces, respectively. The average amount of DU and CU for selected famrs in Isfahan provinces was 55 and 63 percent and for Fars provinces was 64 and 76 percent, respectively. The average amount of PELQ and AELQ in Isfahan province were 45 and 38 percent and that was 53 and 46 percent in Fars province. The average amount of PELQ in selected farms in Fars province was 18 percent higher than that in Isfahan province. The potential effeceincy of the low quarter was lower than the acceptable range in evaluated irrigation systems. It was attributed to the low uniformity of water distribution, the wind drift and evaporation losses and as well as, inappropriate working pressure due to the improper irrigation system design and operation. Considering the encountered areas with water and energy shortages and most importantly, climatic constraints (extreme heat and existence of severe wind on most agricultural areas), a medium pressure sprinkler systems (small sprinklers), drip irrigation system or low pressure systems were suggetced for these provinces.
