Evaluating the performance of irrigation systems by providing the possibility of increasing irrigation efficiency in those systems is an important factor in the field of water resources management. In this study, the performance of three systems were evaluated, including linear move sprinkler irrigation systems in maize, sugar beet and alfalfa fields of Magsal Agro-industrial Company which is located in Qazvin plain, in 2013. In order to assess the performance of the cited irrigation systems, the coefficients of uniformity were determined by creating a water collection network of cans to gather the irrigation water in different points of the net. The results indicate that the average values of the coefficient of uniformity and the coefficient of distribution uniformity are 73.3 and 61.9, respectively which express low amounts of the coefficients in the systems of interest. On the other hand, the potential efficiency of water use (PELQ) and actual efficiency (AELQ) in the lower quarter were calculated as 68.21 and 50.6, respectively. These results depict bad management and exploitation. Likewise three-dimensional model of the spatial distribution of the output water of the sprinklers at the field level was drawn by GS + software. Overall, results reveal that the evaluated linear move sprinkler irrigation systems in this experiment were not good in performance which the main reasons can be suggested as weaknesses in management of them.
