Abstract :
Tailing is one of waste that?s produced by mining activity at PT. Freepot Indonesia (PT FI) and it also called as sirsat, which is the representing abbreviation from sand in mining. This Sirsat is placed at Modada ( Modified Ajkwa Deposition Area), that?s an area which is modified and managed operation of sirsat and, broadly about 235 kilometres, limited by West Levee and East Levee. The System that is used by exploit the river stream to conduct the tailing from mountain area to the sediment area in ModADA. The riverflow consists the result of material erosion that is correlated with the friction factor, velocity of sedimentation and geometric configuration that is assumed as bedriver morphology. Grain size is one of the factor that influence the bedriver morphology that is used as the parameter in this research. The measurement and gathering of grain size sample that have been conducted since 1997 until now and in the same time, The Parameter analysed by using statistical approach like mean, variant and Standard deviation. Estimation of the bedriver morphology is conducted by using the analysis of characteristic chanel form. The result of estimation the bedriver morphology can be used to predict the pattern of sedimentation as long as the riverflow in Ajkwa Lowland, Timika, Papua.
