Abstract

Banjir adalah salah satu bencana alam yang sering melanda Indonesia, khususnya di wilayah perkotaan seperti Kota Semarang yang menempati peringkat kedua jumlah bencana di Jawa Tengah. Salah satu penyebab utama banjir di Semarang adalah Banjir Kanal Timur (BKT), yang meskipun dibangun sebagai infrastruktur pengendali banjir, kini menunjukkan penurunan kapasitas akibat sedimentasi, penurunan muka tanah, kenaikan permukaan laut, dan buruknya pengelolaan drainase. Kejadian banjir terbaru, termasuk banjir pada Maret 2024 dengan genangan hingga 70 cm, menunjukkan perlunya perencanaan pengendalian banjir yang komprehensif. Penelitian ini bertujuan untuk menganalisis debit banjir rancangan dengan menerapkan metode Hidrograf Satuan Sintetik (HSS) Nakayasu, memodelkan perilaku banjir menggunakan perangkat lunak HEC-RAS 6.3 pada kondisi eksisting, serta merancang upaya pengendalian banjir berupa normalisasi sungai dan perencanaan tanggul sepanjang 14,70 km kanal. Penelitian menggunakan data curah hujan 10 tahun dari empat stasiun serta data pasang surut dari Stasiun Meteorologi Tanjung Emas. Hasil studi ini diharapkan memberikan gambaran teknis mengenai zona rawan banjir, strategi mitigasi berbasis simulasi, serta estimasi biaya awal penanganan. Penelitian ini berkontribusi pada pengembangan strategi pengendalian banjir yang berkelanjutan di Kota Semarang.

Abstract

Parit Raya is part of the drainage system of the Ngasinan River in Trenggalek and Tulungagung regencies. It is designed to reduce flooding and manage waterlogging caused by the construction. However, in the rainy season, the high flow velocity often causes damage to groundsills, triggering riverbed degradation or aggradation. This study aims to analyze the degradation and aggradation phenomena in Parit Raya River and the effect of two groundsill to reduce these actions using Hydrologic Engineering Center’s River Analysis System (HEC-RAS) simulations. The flow and sediment dynamics analysis uses Meyer Peter Müller (MPM), Engelund Hansen, and Laursen Copeland methods. The research locations focus on three river sections, consisting of 74 cross-sections, with two groundsills. By using the MPM, Englund-Hansen, and Laursen-Copeland methods modeled in HEC-RAS 6.0.0 software, this study can help in evaluating the effectiveness of groundsills in controlling sediment, preventing excessive erosion, and maintaining the stability of other hydraulic structures in rivers. The analysis reveals that conditions upstream of the groundsill tend to experience aggradation due to sediment deposition in STA 120, STA 103.60, and STA. 79.40, downstream conditions are characterized by degradation, indicated by riverbed erosion resulting from increased flow velocity between STA 120 and STA 47. Among the methods applied, the MPM and Engelund-Hansen methods provided results that closely align with field conditions compared to the Laursen-Copeland method.
