Technical Evaluation of Performed Centre Pivot Systems Case Study: Bardsir and Rayen of Kerman

Document Type : Research Paper



      The importance of proper management of water resources in Kerman, because of limited and water resources crisis is very high. This research has been based on two farm included two center pivot systems in Kerman’s Bardsir and Rayen. For this purpose, the evaluated parameters included Application Efficiency (AE), Potential Application Efficiency of Low Quarter (PELQ), Actual Application Efficiency of Low Quarter (AELQ), and Distribution Uniformity of low quarter and half quarter (DU), Christiansen’s Uniformity coefficient (CU) and adequacy of irrigation is calculated. The result of comparing two Center pivot systems is that Rayen’s Center pivot system with a CU, Adequacy of irrigation and also DU are higher, but AELQ is lower than the recommended value and the difference between AELQ and PELQ shows weakness in design, performing of the system and supervision. Otherwise because of proximity between AELQ and PELQ at Bardsir’s center pivot system indicated purposely paucity in terms of management.
