Strategy in river flood control

Abstract

In February 2018, there was a flood due to the overflow of the Cisanggarung River, one of the affected areas is the population in Ciledug Sub-district, Cirebon, West Java, Indonesia. The purpose of this research is to control the flood of the Cisanggarung River. This study analyzes the amount of water flow that flows in the river crossing capacity. The method used is floods routing from rainfall data using Nakayashu hydrological analysis. The results of the analysis show that the amount of discharge for river capacity is 658 m3/s, while the flood discharge is 784 m3/s, so the river capacity cannot accommodate water. The solution is to floods control by building embankments and normalizing river flow from existing waste. With plans to build embankments and normalize the river, the river capacity becomes 940 m3/s.
