Abstract

Bili-Bili reservoir is a procurement to overcome the crisis of drinking water, electricity, irrigation and the flooding. Every second, these sediments increasing, piling and lifting up the base in reservoir. The problem that must be concerned nowadays is 75 million rrr' wash-load that has stacked in the bottom of the reservoir and almost reaches intake drain. This study aims to estimate the volume of settled sediment flood discharge plan based on the T-year period using rainfall data obtained from rain stations which influenced the location of research, namely; Senre station, Pamukkulu station and Malino stasion, from 1996-2015. The results of this study indicate that the relationship between suspended load (QmJ and water discharge (Qw) obtained by curve equation of sediment; i.e, y = 0,0822xO 8558 with a correlation coefficient (R) = 1.0, this indicates the relationship between suspended load (Qsm) and water discharge (Qw) has directed positive relationship is perfect which is among 0.6<R<1.0. Based on the above curve equation sediment, sediment discharge obtained drift (QsJ amounting to 37,044.12 tons/day and bed load base on (Qsd) obtained 37,044.12x20% = 7,408.82 tons/day, the total amount of bed load obtained 44,452.94 tons/day. So the volume of settled sediment is obtained at 44,452.94 tons/day = 16,225,323.1 m' by flood discharge of 2,341.110 mvsec in a period of 10 years. For the condition settles volume of sediment suspended load based on data obtained during the 8 years of the Central River Region Pompengan Jeneberang (CRRPJ) in 2012 as many as 1,317,413.68 m ' while the estimation results obtained by this research as many as 16,225,323.1 m '. It shows an increase in volume of settled sediment to the Bili-Bili reservoir in the form of sediment transport from 2012-2015 as many 14,907,909.42 rrr',
