Abstract

Perencanaan pelimpah Bendungan Leuwikeris merupakan salah satu kajian penting dari perencanaan Bendungan Leuwikeris. Tahapan awal studi ini adalah merencanakan perencanaan pelimpah yang sesuai dengan pertimbangan topografi, hidrologi, dan hidrolika. penelitian dilakukan dengan menggunakan data hujan tahun 2008-2017. Analisis curah hujan mengunakan metode log pearson III, perhitungan intensitas hujan menggunakan metode mononobe dan analisis debit banjir rencana menggunakan metode HSS Nakayasu. Berdasarkan hasil analisis perhitungan yang telah dilakukan didapatkan debit inflow kala ulang 1000 tahun 1489,223 m3/det dan kala ulang PMF 4648,564 m3/det, debit outflow kala ulang 1000 tahun 1356,872 dan kala ulang PMF 4394,393 m3/det. Hasil volume galian pada pelimpah (spillway) samping berada pada elevasi +150 m dengan volume sebesar 415.625 m3 dan pelimpah (spillway) terjunan berada pada elevasi +180 m dengan volume galian 734.375 m3.

The plan of Leuwikeris Spillway is one of importan stage from planning Dam Leuwikeris. Initial stages of this study is to plan corresponding to the spillway planning with consideration topography, hydrology, and hydraulics. Research was conducted using rainfall data for 2008-2017. Rainfall analysis using the Log Pearson III method, calculation of rain intensity using the Mononobe method and analysis of planned flood discharge using the Nakayasu HSS method. Based on the results of the analysis of calculations that have been carried out, it was found that the 1000-year return inflow rate was 1489,223 m3 / sec and the PMF return period was 4648,564 m3 / sec, 1000-year return outflow 1356,872 and PMF 4394,393 m3 / det. . The result of the volume of excavation on the side spillway is at an elevation of +150 m with a volume of 415,625 m3 and the spillway of the falls is at an elevation of +180 m with a volume of excavation of 734,375 m3.
