Abstract

Energy consumption and energy cost in irrigation systems have been important issues due to energy charge increase in recent years. In this study, theoretical basis of pressurized irrigation systems management and technical factors that affect energy costs were studied and the optimum system design criteria for energy consumption were identified. In addition, energy consumptions of 45 pressurized irrigation systems in Qazvin province were evaluated. These irrigation systems types were classic sprinkler, center pivot, linear move, and trickle. The energy requirements of these systems for supplying a unit volume of water were obtained as 0.290, 0.250 and 0.202 KWh/m3, respectively. The results show the importance of irrigation systems selection in energy costs saving in national and regional plans. At last, energy consumption and related costs for various pressurized irrigation systems were studied for the main crops in Qazvin irrigation network. These results can be useful in deciding cropping pattern and economic studies.
