Abstract

This study discusses the review of Spillway planning in the Karalloe Dam project. The spillway serves to drain excess water from the dam to avoid overtopping the dam back to the river. Three methods are used in the calculation of rainfall analysis, namely the Gumbel Method, Pearson Log Type III, and Normal Log. Design flood discharge was analyzed using the Gama-I Synthesis Unit Hydrograph Method. Spillway planning is planned based on differences in design flood discharge and Spillway lighthouse type. The results of this study obtained a design flood discharge of 613,251 m3 / sec and high energy above the lighthouse of 2,902 m using the type of round lighthouse.

Abstract

Penelitian ini membahas tentang tinjauan perencanaan Spillway pada proyek Bendungan Karalloe. Spillway tersebut berfungsi untuk mengalirkan air yang berlebihan dari bendungan agar tidak terjadi overtopping pada bendungan kembali ke sungai. Digunakan tiga metode dalam perhitungan analisa curah hujan yaitu Metode Gumbel, Log Pearson Tipe III, dan Log Normal. Debit banjir rancangan dianalisis menggunakan Metode Hidrograf Satuan Sintesis Gama-I. Perencanaan Spillway direncanakan berdasarkan perbedaan debit banjir rancangan dan tipe mercu Spillway. Hasil penelitian ini didapatkan debit banjir rancangan sebesar 613,251 m3/det dan tinggi energi di atas mercu sebesar 2,902 m dengan menggunakan tipe mercu bulat
