Abstract

In order to manage watersheds, especially in mountainous areas that are not adequately station hydrological phenomena simulation is important. In this study, the SWAT model used to simulate hydrologic basin Eskandari. Calibration and validation of models for the periods 2006-1992 and 2009-2015, respectively, using the algorithm SUFI2 in software SWAT CUP was done. To evaluate the simulation results of the index R2, bR2, NS was used. In the calibration coefficients, R2, bR2 and NS, respectively, 0. 76, 0. 53 and 0. 76 in the validation, 0. 56, 0. 29 and 0. 52 was obtained. Sensitivity analysis showed that 23 parameters affecting runoff curve number was identified as the most important parameters and parameters constant groundwater discharge, Groundwater delay time and soil available water to more sensitive respectively. Indicators and charts obtained simulate monthly runoff rate, indicating that the calibration of the model has been more successful. The model has been able to determine the time of peak flow well, but peak flow estimates are higher than the actual values, which can be attributed to the distribution of rain gauge stations and the interpolation of rainfall.
