Accurate simulation runoff process can have a significant role in water resources management and related issues. The inherent complexity of  this process makes difficult the use of physical and numerical models. In recent years, application of intelligent models is increased a powerful tool in hydrological modeling. The aim of this study was the application of the Gamma test to select the optimal combination of input variables for runoff modeling in Sofi Chay. Streamflow modeling was performed based on the optimum number of  the selected variables using the artificial neural network (ANN) and Support vector machine (SVM) methods .Gamma test results showed that monthly runoff with six antecedent runoff values  provide better results to predict. Runoff simulation using support vector machines and artificial neural network models also showed that the best input structure will be delayed until six to predict of next month runoff. Among to models with the same input structure, support vector machine have relatively high efficiency compared to artificial neural network .
