Title

SIMULATION OF DISCHARGE AND NITRATE IN TALLAR BASIN USING SWAT MODEL

Pages

  45-60

Abstract

 In order to controlling and reducing water pollution of surface water and measures to reduce these emissions require environmental programs at watershed scale and also to ensure the cost-effectiveness of such programs, the first stage is determining critical areas that produce polluted runoff. Process-based HYDROLOGICAL MODELs are useful tools for simulating of watershed processes. In this study SWAT model was used for discharge and nitrate simulation in Tallar river Basin. The modeling results calibrated and validated using SWAT-CUP software and then its evaluated using statistical indicators. For Sensitivity analysis of discharge and nitrate used from 25 and 11 parameters respectively, that the curve number (CN) recognized as the most sensitive parameter. The determination coefficient of discharge and nitrate calculated with rates of 0.68 and 0.75, and VALIDATION obtained with rates of 0.65 and 0.83, respectively. The NS coefficient for CALIBRATION process of discharge and nitrate obtained 0.67 and 0.84, respectively. Also, for VALIDATION process were 0.62 and 0.63, respectively. Finally, the discharge and nitrate maps developed for each sub-basins. The results of this study showed that the SWAT model could simulate quality and quantity of Tallar river watershed. Therefore, this model can be used as a useful tool for WATER RESOURCES MANAGEMENT and planning in this watershed.
