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

This study aims to review the planning and design of the Diversion Tunnel at the Karalloe Dam. Calculation of design rainfall analysis uses three methods namely the Gumbel Method, the Pearson Type III Log Method, and the Normal Log. The flood discharge was analyzed by the Nakayasu Synthesis Unit Hydrograph Method. Planning the Karalloe Dam Circular Tunnel is designed using a horseshoe shape, with a tunnel length of 583 m, tunnel diameter of 6 m with a height of energy loss in the tunnel of 27 m. The results showed that flood tracking with a 25 year return flood of 492,333 m / sec using a circular tunnel design obtained a tunnel diameter of 6.25 m, with a height of energy loss of 25.741 m, and a planned height of the cofferdam lighthouse +205,241 m
