Abstract
ⶠWe used the Soil and Water Assessment Tool (SWAT) to build a hydrologic model for the Hamadan-Bahar watershed in western Iran. The watershed suffers from an increasing water pollution problem due to agricultural activities. ⶠThe hydrology model was calibrated, and validated with uncertainty analysis. ⶠWe used the calibrated hydrology model and further calibrate it for nitrate leaching and crop yield, using wheat and potato. ⶠWe characterized the spatial and temporal leaching pattern. ⶠIn a follow up work we will suggest a best management practice for the region.
