“…This indicates that along the major rivers in Banyuwangi Regency the erosion rates were still low (a < 26) [30]. Furthermore, according to previous research [15], the average suspended load values along Baru, Setail, Bomo, and Tambong rivers were 1.65 tons/day, 2.18 tons/day, 52.54 tons/day, and 0.30 tons/day, respectively.…”

“…The weirs were still in good conditions, but they still need treatments by draining weir sediment periodically. Then, from previous research [15], it was also known that the bedload transportation along Baru, Setail, Bomo, and Tambong rivers was analyzed to have average bedload values of 0.11 tons/day, 0.26 tons/day, 0.22 tons/day, and 0.10 tons/day, respectively. From the results of the prediction of bedload values from the two studies, it can be seen that the bedload values had the same consistency values when viewed from fluctuations in high and low bedload transportation.…”

“…For the purpose of facilitating the identification and prediction of sediment transport, preliminary research was conducted to generate modeling equations based on suspended load and bedload against river discharge in each watershed in Banyuwangi Regency in the upstream and downstream parts of the rivers [15]. Daily sediment estimates are important for water resource conservation and infrastructure buildings protection.…”

A sediment transportation process may lead to a river overflow. This was the case with 4 major rivers in Banyuwangi Regency, namely Baru, Setail, Bomo, and Tambong rivers. The watersheds in Banyuwangi are shaped alike to bird feathers, belonging to the dendritic drainage type with an elongated drainage form, relatively small discharge, and flooding that occurs for a relatively long time. The use of downstream areas by residents for sand mining indicates a high amount of sediment in the watersheds. The purpose of this study was to model the sediment load in the bird feather-type watersheds along the main rivers of Banyuwangi Regency. Data from water level, flow velocity, and discharge measurements were correlated with the results of suspended load and bedload analyses to create rating curves. Equations for the modeling of the sediment load in the bird feather-type watersheds were generated by regression methods. The results of the modeling of the sediment load in the bird feather-type watersheds in Banyuwangi Regency using the equations above were obtained by the suspended load model qs (tons/day) = 27.0 - 39.0.h (m) – 122.V (m/s) + 71.1.q (m3/s), with R-Sq = 59.4%, and by the bedload model qb (tons/day) = - 0.0758 + 0.0853.h (m) + 0.0585.V (m/s) + 0.165.q (m3/s), with R-Sq = 73.6%. Sediment load modeling can be used as a projection of sediment transport in studies on type C excavations along the major rivers in Banyuwangi Regency.

Besarnya distribusi kecepatan aliran pada Sungai Setail menimbulkan permasalahan, salah satunya yaitu peluapan air sungai yang dapat mengakibatkan banjir karena endapan sedimen yang tinggi. Kecepatan aliran pada Sungai Setail ditambah curah hujan yang tinggi mengakibatkan sungai meluap yang menyebabkan ratusan rumah di Desa Wringinputih, Kecamatan Muncar terendam banjir setinggi 1 meter. Tujuan penelitian ini adalah untuk menentukan angka Reynold dan angka Froude di hulu, tengah dan hilir Sungai Setail. Pengukuran kecepatan aliran menggunakan alat Current Meter. Setelah didapatkan data debit, kecepatan, dan koordinat, kemudian dilanjutkan dengan pengolahan data untuk mengetahui angka Reynold dan angka Froude untuk menentukan karakteristik hidraulik sungai dan di input dalam program Surfer untuk mengetahui bentuk dan kontur distribusi kecepatan aliran Sungai Setail. Pada bagian hulu Sungai Setail diperoleh kecepatan rerata sebesar 0,63 m/detik, dengan debit rerata sebesar 0,77 m3/detik, rerata angka Reynold sebesar 1789288,36 termasuk jenis aliran turbulen, dan rerata angka Froude sebesar 0,38 tipe aliran subkritis. Pada bagian tengah Sungai Setail didapatkan kecepatan rerata sebesar 0.32 m/detik, debit rerata sebesar 0.77 m3/detik, rerata angka Reynold sebesar 112775,85 termasuk jenis aliran turbulen, dan rerata angka Froude sebesar 0,19 tipe aliran subkritis. Lalu pada bagian hilir Sungai Setail diperoleh kecepatan rerata sebesar 0.24 m/detik, debit rerata sebesar 0,96 m3/detik, rerata angka Reynold sebesar 185107,50 termasuk jenis aliran turbulen, dan rerata angka Froude sebesar 0,07 termasuk tipe aliran subkritis.
