Abstract

. In the modeling research, the correlation formulation between one variable to a group of other variables can be solved by dimensional analysis or statistics. Dimensional analysis would be easy and relatively quick to obtain results in the certain cases. There are several methods of analysis dimensions that are often used, among other methods are Buckingham's, Indicial, and matrix. The following article will use the dimensional analysis Buckingham's method to determine the correlation of flushed sediment concentration (C) and a group of other variables (HW , g , ρw , QW , Hs , ds , ρs , v) in the flushed sediment modeling. The next step its will be known correlation maximum concentration of sediment flushed results against upstream water level at each sediment thickness (d) which has been deposited. Modeling scale of 1 : 66.67, use sediment artificial with coal dust. The thickness of sediment that settles at the assumed 1.5 ; 2.25 ; 3.00 ; 3.75 ; 4.50 cm. The flushed sediment concentration measurements were conducted during the upstream water level every drop of 1.50 cm, from the initial water level 13.90 cm. The results of the analysis correlation can be obtained : C / ρ s = ƒ( Qw.v / H3 w . ɡ), and the maximum concentration of flushed every sediment thickness can be obtained at water level : Hw = 10,58 Hs-0,12Hw
