Abstract

Abstrak Banjir merupakan salah satu bencana alam di mana air yang berlebihan tidak mampu dialirkan ke sungai maupun saluran saluran yang ada (drainase). Kecamatan Matangkuli merupakan salah satu daerah terdampak banjir dari Krueng Keureuto. Hampir setiap tahun terjadi banjir yang merugikan aspek sosial ekonomi masyarakat. Oleh karena itusebagai studi awal terlebih dahulu perlu dilakukanperlu dilakukan analisa dampak banjir terhadap kawasan Matangkuli di sepanjang sungai Keureuto. Curah hujan rencana dianalisis dengan periode ulang 20, 50 dan 100 tahun. Analisis hidrograf banjir menggunakan persamaan Nakayasu. Untuk melakukan simulasi aliran sungai menggunakan software HEC-RAS Mapper. Hasil yang diperoleh pada lokasi tinjauan, sungai tidak dapat menampung debit banjir rencana. Selain itu, diprediksi genangan banjir sedalam 1-2 meter dengan klasifikasi bahaya banjir menengah hingga berat. Kata kunci: banjir, HEC-RAS, debit rencana Abstract Flood is one of the natural disasters where excessive water is not able to collected by existing channels (drainage). Kecamatan Matangkuli is one of the flood-prone areas around Krueng Keureuto. Almost every year there are floods that harm the community. Therefore, as a prior study, it is necessary to analyze the impact of Krueng Keureuto flood on the Matangkuli area. Planned rainfall was analyzed with return periods of 20, 50 and 100 years. Flood hydrograph analysis using the Nakayasu equation. HEC-RAS Mapper is used to perform river flow simulation. Results show that the river section cannot accommodate the planned flood discharge. In addition, hazard flood is classified medium to high with depth flood 1-2 meters. Keywords: flood, HEC-RAS, planned rainfall
