Water scarcity has limited the expansion of agricultural development. Sprinkler irrigation systems can enhance water use efficiency; however, poor design, improper operation, and inadequate maintenance reduce their performance and increase water losses. Accurate design, proper management, and regular maintenance are the three main pillars for improving the performance and sustainability of these systems. The aim of this study was to evaluate the hydraulic performance, design quality, and operation of several sprinkler irrigation systems in Qorveh Plain, Kurdistan Province. Eight classic solid-set sprinkler irrigation systems equipped with portable sprinklers were selected and evaluated. To assess their performance, the Christiansen’s Uniformity Coefficient (CU), Distribution Uniformity (DU), Potential Low Quarter Application Efficiency (PELQ), Actual Low Quarter Application Efficiency (AELQ), Wind Drift and Evaporation Losses (WDEL), Deep Percolation Losses (DP), and Adequacy of Irrigation (ADirr) indices were determined. The average values of these indices for the eight farms were 71.67%, 61.66%, 52.45%, 52.07%, 9.54%, 22.78%, and 68.31%, respectively. The results indicated that all systems had low application efficiency, and the water distribution uniformity was below the recommended range proposed by Merriam and Keller (1978). Furthermore, due to water shortages, the potential and actual application efficiencies were equal in all farms except for farm A5. The low potential application efficiency was mainly attributed to improper design and construction, with the most critical factor being unsuitable operating pressure. The simultaneous use of more than one sprinkler per lateral line and the use of sprinklers with different models and specifications, along with poor system design, installation, operation, and maintenance, were the main causes of reduced distribution uniformity. Overall, the results revealed that despite multiple design and implementation issues, the primary reason for the poor performance of the classic solid-set sprinkler irrigation systems with portable sprinklers in Qorveh Plain was improper management, maintenance, and operation.
