Abstract

Evaluation of sprinkler irrigation systems while in operation is indispensable for the assessment purposes. Throughout the present study, the performances of hydraulic center -pivot sprinkler irrigation systems (A.B) and solid-set irrigation system equipped with portable sprinklers were evaluated. Within this concept, the common indicators of assessment were made use of. The results indicated that the solid-set irrigation system with Cu 65.52 and PELQ 47.5 is of a lower performance in comparison with the others. Also, sprinkler irrigation system B with a Cu of 88.36 and PELQ of 74.28 is of a better performance than the others. Soil moisture uniformity coefficients under irrigation systems A, B along the lateral pipes were respectively recorded as 81.35 and 85.77 which are very acceptable. The results also indicated that an irrigation system is the most sensitive to wind, which can best be the reason for low coefficients of uniformity.
