Pemodelan Debit Banjir Sehubungan Dengan Prediksi Perubahan Tutupan Lahan Di Daerah Aliran Ci Leungsi Hulu Menggunakan Hec-Hms, Kuswantoro Marko, Faris Zulkarnain

Jurnal Geografi Lingkungan Tropik (Journal of Geography of Tropical Environments)

Upper Ci Leungsi catchment area is one of the catchments that has an important role in contributing water runoff to downstream areas i.e. Bekasi City. High population growth has led to significant changes in land use that impact in potentially increased surface runoff causing flooding. This study aims to estimate the flood discharge that will occur in relation to land cover change prediction in 2020, 2025, and 2030. The SCS-CN method is used for calculation of runoff volume and synthetic unit hydrograph using HEC-HMS. The CN value obtained on the existing data i.e. 72.5; 74.4; and 75.4 in 2005, 2010, …
