Technical Evaluation of Sprinkler Irrigation Systems in Arak, Iran

S. Broomand Nasab, F. Baradarane-Hezave and M. Behzad

The scarcity of water resources is one of the crises most commonly experienced in different regions of the world especially in Iran. By the implementation of pressurized irrigation projects in this region, it is likely to enhance the consumption efficiency. One of the indispensable components in any irrigation exercise in order to improve the irrigation systems is evaluation activity. In the present study, nine different sprinkler irrigation systems i.e., the solid set system and wheel move systems in the Arak agricultural area, Iran were selected, tested and evaluated. Values of Coefficient Uniformity (CU), Distribution Uniformity (DU), Potential Efficiency of Water Application (PELQ), Actual Potential Efficiency of Water Application (AELQ) and maximum pressure difference (ΔPmax) in solid set systems are 76.16, 64.53, 55.56, 51.48 and 45.23%, respectively and for wheel move systems are 82.86, 76.02, 67, 67 and 29%, respectively. Average losses due to wind and deep percolation values were determined as 12.78 and 32.83%, respectively for solid set systems and 12.22 and 2.53%, respectively for wheel move systems. In solid set systems all of parameters failed to meet the expected values, however wheel move systems showed a better performance with mild wind. In general, it can be claimed that the main problems of sprinkler irrigation systems are deficient design and implementation, low distribution uniformity, low water pressure, deficient distribution of pressure, insufficient lengths of lateral pipelines in addition to poor quality equipment utilized and deficient management and maintenance processes.
