The drip irrigation systems are an ideal potential in water distribution with high efficiency, it is considered to be a safe way toward better usage of water supplies. In the direction of quantity, one must also pay attention to the quality of the plans and must be evaluated. How this evaluation is easier and faster and cheaper, it will be more economical, usage of computer facilities and presenting mathematical and computer models are the best way. Besides, by using models, it does not need to do most of measurements in site and without any payment or with the lowest payment, we will be able to research scenarios and different conditions and see the results in the models and finally apply the suggestions and improving and management solutions. In this study, the existing drip irrigation system that applied in Shahmirzad of Semnan province(IRAN) was survived and evaluated according to plan and performance and management and finally mathematical model was performed too. The evaluation parameters were chosen on the basis of Soil Conservation Services (SCS). The System evaluated with EUm of 85.7 Percent, ERF of 0.64 and EUs of 54.8 percent. Average amount of EUm in the whole manifolds under investigation was about 87.3 percent and ERF of 0.79.
