Arimbi, Rovita Yuniarti and Dr. Ir. Sumiadi, ST., MT. and Bambang Winarta, ST.. MT.. Ph.D (2022) Pemodelan Aliran 1D Menggunakan Aplikasi HEC-RAS 5.0.7 untuk Menentukan Pengendalian Banjir di Sungai Jatiroto. Sarjana thesis, Universitas Brawijaya.
Abstract
Sungai Jatiroto merupakan sungai yang terletak di perbatasan Kabupaten Lumajang dan Kabupaten Jember dengan panjang sungai utama ± 29,30 km, dan termasuk sungai orde 2 yang mana bagian hilir sungai ini bertemu dengan Sungai Bondoyudo. Ketika elevasi muka air di Sungai Bondoyudo lebih tinggi dibandingkan Sungai Jatiroto, maka terjadi aliran balik pada Sungai Jatiroto. Adanya kenaikan tinggi muka air di Sungai Jatiroto mengakibatkan aliran air sungai mengalami overtopping. Menurut pernyataan masyarakat sekitar Sungai Jatiroto, bahwa sejak tahun 1992 sampai 2020 terjadi kerusakan tanggul di titik lokasi yang sama. Kerusakan tanggul tersebut dikarenakan adanya kenaikan tinggi muka air di Sungai Jatiroto dan mengakibatkan banjir. Selain itu juga kondisi kapasitas sungai yang berkurang dikarenakan adanya sedimentasi yang terjadi di Sungai Jatiroto. Maka dari itu diperlukan analisis pemodelan aliran di Sungai Jatiroto untuk menentukan alternatif penanganan banjir yang tepat dalam mengatasi masalah-masalah tersebut.
English Abstract
Jatiroto River is a river located on the border of Lumajang Regency and Jember Regency with the main river length of ± 29,30 km, and includes a river of order 2 where the lower reaches of this river meet the Bondoyudo River. When the elevation of the water level in the Bondoyudo River is higher than that of the Jatiroto River, there is a reverse flow in the Jatiroto River. The increase in water level in the Jatiroto River has caused the river water flow to be overtopping. According to a statement from the community around the Jatiroto River, from 1992 to 2020 there was damage to the embankment at the same location point. The damage to the embankment was due to a high rise in water levels in the Jatiroto River and resulted in flooding. In addition, the condition of the river capacity is reduced due to sedimentation that occurs in the Jatiroto River. Therefore, it is necessary to analyze the flow modeling in the Jatiroto River to determine the right alternative to flood management to overcome these problems.
