Abstract

Badeng watershed is one of the important watersheds in the Banyuwangi Regency. In the years 2018, Alas Malang Village, there was a flash flood. This flooding occurs because of the high rainfall intensity and causes erosion and landslides in the upstream area of Badeng Watershed, recorded in Badeng Watershed 26.16 m3/second from the drainage capacity of 3.8 m3/sec. The condition of land cover changes causes the complexity of hydrological conditions in Badeng Watershed. This causes the need for the use of models in watershed management activities. In hydrological modeling using the help of SWAT software. Soil and Water Assessment Tool (SWAT) is a hydrological model of watershed-scale that is based on a physical, deterministic, and continuous basis. Spatial data in the form of digital maps DEM, land use, soil type, slope, and daily rainfall and climate data. For calibration using river discharge data for 2010-2013 and validation using 2018-2019 data. The results of SWAT hydrological modeling have a total average annual rainfall of 10467.91 mm/yr, total evapotranspiration of 1577.21 mm/yr, total potential evapotranspiration value of 3722.61 mm/yr, total percolation value of 6760.05 mm/yr, total surface runoff value of 2128.41 mm/yr, total sediment discharge value of 29779.44 tons/yr, total sediment yield value of 250.65 tons/ha/yr, and total erosion rate value of 601.92 tons/ha/yr. With the results of the calibration with a determinant coefficient (R2) of 0.78 and NSE of 0.69, for validation with a determinant coefficient (R2) of 0.75 and NSE of 0.70.
