Pengaruh Tata Guna Lahan Terhadap Hidrograf Aliran Di Sub-Sub DAS Keyang-Slahung-Tempuran Menggunakan Model SWAT

Generally, area development leads land use changing that may cause surface runoff increases. These alterations are responsible for flood and inundation in certain areas. Soil Water Assessment Tool (SWAT) can be used to perform rainfall-runoff model. Hence, the flow change estimated comprehensively. To ensure reliability of model, calibration validation required. The stages were conducted using SUFI-2 (Sequential Uncertainty Fitting Version 2) method determine most influential or sensitive parameter. Meanwhile, test was assessed , NSE, PBIAS methods. provides a good result. In advance, this research shows increase forest decreases peak during occurrence.
