Analisis Hidrolika Untuk Saluran Drainase Perumahan (Kasus : Puri Dander Asri Ngumpakdalem Kabupaten Bojonegoro)

Abstract

Puri Dander Asri Residence in Ngumpakdalem Village, Bojonegoro Regency has problem in drainage system. It have been flooded during rainy season. It is because the drainage has not support the runoff when it rains. The aim of the research to design drainage model alternative to avoid the flooded when it happens. By calculating flood debit and hydraulic analysis, it result the segment I has h₁<h₀ (0,97 < 1,679), the segment II has h₁<h₀ (0,97 < 1,437), and the segment III has h₁<h₀ (1,2 < 2,328). Base on result it showded that drainage chanel capacity is not accomodate water volume when it rains.
