Abstract
Pembangunan Bendungan Surumana yang terletak di Kabupaten Donggala, Provinsi Sulawesi Tengah diprioritaskan untuk mensuplai kebutuhan air irigasi, air baku domestik, industri, dan sebagai pembangkit listrik. Salah satu prosedur dalam perencanaan bendungan adalah melakukan analisis hidrolika pada uji model tes pelimpah samping Bendungan Surumana dengan skala model tanpa distorsi (undistorted) 1:60. Analisis hidrolika dilakukan pada approach channel, pelimpah, saluran samping, saluran transisi, saluran peluncur, peredam energi, escape channel, dan hilir Bendungan Surumana. Analisis ini menggunakan uji model tes sebagai kontrol untuk membandingkan hasil dengan perhitungan teoritis. Hasil pengujian model tes menunjukkan bahwa bagian escape channel, pelimpah, saluran samping, saluran transisi, saluran peluncur, dan peredam energi mampu mengalirkan aliran dengan debit sampai dengan QPMF tanpa menyebabkan overtopping. Hasil perhitungan teoritis terhadap profil muka air mendekati dengan hasil pengujian model tes pada debit Q100th dan Q1000th. Bendungan Surumana pada debit Q100th, Q1000th, dan QPMF aman terhadap bahaya kavitasi baik dari hasil perhitungan maupun dari pengukuran pada bacaan piezometer model tes. Pada hilir escape channel ditemukan adanya gerusan lokal terdalam. Pendekatan metode teoritis yang hasilnya mendekati hasil saat pengujian model tes adalah dengan menggunakan rumus Zimmerman dan Maniak.
English Abstract
Construction of the Surumana Dam where it is located in Donggala Regency, Central Sulawesi Province is prioritized to supply water for irrigation, domestic water, industry, and as a power plant. One of the procedures in dam planning is to conduct hydraulic analysis on the model test of the Surumana Dam's side channel spillway with an undistorted scale model of 1:60. The hydraulic analysis is conducted on the approach channel, spillway, side channel, transition channel, launch channel, energy dissipator, escape channel, and downstream of Surumana Dam. This analysis uses the model test as a control to compare the results with theoretical calculations. The results of the model test show that the escape channel, spillway, side channel, transition channel, launch channel, and energy dissipator are able to flow water at the design discharge up to QPMF without causing overtopping. The theoretical calculations of the water surface profile closely approximate the results of the model test at the Q100th and Q1000th discharge. The Surumana Dam is safe from cavitation risks at the Q100th, Q1000th, and QPMF discharge, both based on the theoretical calculations and measurements from the model test's piezometer readings. In the downstream escape channel, the deepest local scour was found. The theoretical approach that yields results close to the model test is achieved using the Zimmerman and Maniak formula.
