Considering the critical conditions that have occurred in recent decades for water resources of the country, agricultural managers are considering developing micro-irrigation systems in agricultural lands, so for their sustainable development and utilization, the evaluation of these systems is necessary. In this regard, the technical and hydraulic performance of 9 irrigation systems in Isfahan province was evaluated. In this experiment, some field measurements were taken to obtain the required parameters for system evaluation. Assessments were made based on the SCS guidelines. The results obtained from the calculation of the evaluation parameters show that amounts of coefficient of emitter discharge variation (qvar) was less than 10% for 33% of the projects, ranging from 10 to 20% for 44 percent of the projects, and over 20% for the rest of the projects, qualified as favorable, acceptable and unacceptable, respectively. The amounts of distribution uniformity (DU), in 22% of projects was more than 90%, 55% between 80 to 90% and the rest between 70 to 80%, qualified as excellent, good, and fairly good. The potential application efficiency of low quarter (PELQ) and application efficiency of low quarter (ALEQ) were between 42.4 to 78.1 % and between 47 to 81.5 percent, respectively, which is moderate. Inappropriate pressure in blocks, deficient skills of the operators, dripper clogging, and lack of proper maintenance for filters, reduce PELQ and AELQ in some projects.
