Analisis Ketersediaan Air dengan Metode Thomas Fiering di Kali Krukut, Jakarta

Abstract

The population in Kali Krukut river basin increased from year to year, so water demand in Kali Krukut increased. This research aimed to analyze the water availability in Kali Krukut using Thomas Fiering method. Based on discharge data from 2001-2009, analyses were performed to estimate the amount of discharge in 2010-2020. The result showed that a maximum discharge would occur in February 2017 approximately 20,80 m3/sec, while a minimum discharge would be 0,8554 m3/sec in December 2014 and 0,0569 m3/sec in December 2015. By 2020, the Goverment planned to increase food security, so a good water irrigation system is needed. Based on the result, the maximum water availability in rainy and dry season could fulfill the water demand, but the minimum water availability in rainy and dry season couldn’t fulfill the water demand. To solve this problem, the Goverment must create a well plan in order to manage Kali Krukut.
