Development of Evaluation Model for Automatic Control Systems in Irrigation Networks

For performance improvement and higher flexibility in irrigation networks، application of automatic systems are expanding and evaluation of their success for achieving the objectives is necessary. Considering various equipment، algorithms، and their applications in different levels of irrigation networks، performance of automatic systems is a function of the performance of all elements، therefore development of performance evaluation model which takes into account all required aspect is necessary. In this study for performance evaluation automatic systems in irrigation networks، INACSEM model is developed، using classical method in terms of technical and general aspects. Technical aspect includes equipment، software and control structures، and general aspect consists of management، social، economic and environmental aspects. Result of the model for automatic monitoring systems (Arian، 2000) in Aghili canal of Gotvand irrigation network shows that performance of the system is 63% with 80% credibility. The result show that the developed model is a suitable tool for performance evaluation of automatic systems used in irrigation networks، which considers all necessary aspects of performance evaluation of automatic systems، and shows the problems of each element of the system.
