Abstract

Todays, productivity and efficiency of irrigation have been in the center of the many water-related issues. By using sprinkler irrigation systems in addition to watering easier and automatic, that is a device for raising water application uniformity and efficiency which ultimately will save water consumption and production increase. In this study, four fixed irrigation systems of Khorramabad city were selected, tested and evaluated. Values of application efficiency (AE), combination efficiency (Ec), potential efficiency in low quarter (PELQ), application efficiency in low quarter (AELQ), adequacy irrigation (ADirr), wind and evaporation losses (WDEL) and deep percolation losses (DP) in solid set systems are 56.82, 59.86, 47.21, 45.71,81.64, 13.12, 30.09, respectively. Measured parameters were less than expected. All systems have a low applicability and combined efficiency. High losses caused reduction of applicability and combined efficiency. In one system, the irrigation was done completed, but deficit irrigation in other systems caused equality of application efficiency potential with application efficiency.
