Peningkatan intensitas curah hujan, sedimentasi sungai, dan penurunan kapasitas penampang menyebabkan Sungai Kali Gondang tidak mampu mengalirkan debit banjir secara optimal sehingga memicu terjadinya luapan yang menggenangi permukiman dan infrastruktur di sekitarnya. Penelitian ini bertujuan menganalisis kapasitas hidraulika penampang Sungai Kali Gondang terhadap debit banjir rancangan serta mengidentifikasi potensi luapan sebagai upaya mitigasi banjir bandang. Metode penelitian meliputi analisis hidrologi untuk menentukan curah hujan rencana dan debit banjir rancangan menggunakan metode Hidrograf Satuan Sintetik (HSS) Nakayasu, kemudian dilanjutkan dengan analisis hidraulika menggunakan perangkat lunak HEC-RAS 1D. Simulasi dilakukan pada debit banjir kala ulang 2, 5, 10, 25, dan 50 tahun untuk mengevaluasi elevasi muka air, kapasitas penampang sungai, serta potensi luapan pada setiap penampang yang ditinjau. Hasil analisis menunjukkan bahwa debit banjir rancangan berturut-turut sebesar 1441,557 m\u00b3/det (Q\u2082), 2315,658 m\u00b3/det (Q\u2085), 2446,232 m\u00b3/det (Q\u2081\u2080), 2574,779 m\u00b3/det (Q\u2082\u2085), dan 2651,623 m\u00b3/det (Q\u2085\u2080). Hasil simulasi HEC-RAS menunjukkan bahwa sebagian besar penampang sungai masih mampu mengalirkan debit banjir, namun pada beberapa penampang kritis elevasi muka air telah melampaui elevasi tebing sungai sehingga berpotensi menimbulkan luapan dan banjir pada kawasan di sekitarnya. Kondisi tersebut menunjukkan bahwa kapasitas hidraulika Sungai Kali Gondang belum sepenuhnya mampu menampung debit banjir rancangan, terutama pada kala ulang yang lebih besar. Oleh karena itu, diperlukan upaya mitigasi berupa normalisasi sungai, pengendalian sedimentasi, peningkatan kapasitas penampang, serta pengelolaan daerah aliran sungai secara berkelanjutan guna mengurangi risiko banjir bandang di Desa Gondang.", "eprint_status": "archive", "ispublished": "pub", "creators": [ { "name": { "given": "Sari", "honourific": null, "lineage": null, "family": "Lisa Tyas Hida Sari" } } ], "dir": "disk0/00/00/63/03", "status_changed": "2026-08-26 01:27:22", "corp_creators": [ "Universitas Bojonegoro" ], "rev_number": 51, "metadata_visibility": "show", "userid": 1758, "date": "2026-07-31", "title": "Analisis Hidraulika Penampang Sungai dalam Upaya Mitigasi Banjir Bandang (Studi Kasus: Banjir Bandang Di Desa Gondang, Kecamatan Gondang, Kabupaten Bojonegoro)", "department": "Teknik Sipil", "lastmod": "2026-08-26 01:27:22", "keywords": "Banjir bandang, Hidrologi, Hidraulika, HEC-RAS, Mitigasi, Sungai Kali Gondang" }
