- ABSTRACT Accretion problem on river estuary and navigation channel is caused by sediment accumulation. Sedimentation pattern and process on river estuary and navigation channel is influenced by bed sediment, water current, and marine hydro dynamic. To overcome this problem is relatively expensive. Fluidization method is an alternative for overcoming the problem on river estuary and navigation channel. The goal of this research was to evaluate the influence of fluidization variables, such as perforation diameter(df), perforation distance(a), and perforation position(a ), on the fluidization effects. Physical model test comprised of three studies i.e. Fluidization basic study, influences among parameters and case study on Serang estuary. Basic research of fluidization was conducted using variation of sediment thickness(db), and tube cliameter(D). The affect among parameters was investigated by varying perforation diameter(df), perforation distance(a), perforation position( a ), and sediment thickness (db). The case study on Serang estuary was conducted using scale model of 1:12 From basic research it could be concluded that pressure height needed for fluidization was approximately equal to the sediment thickness (see picture 6) in the fluidization tube. The problem, where the pipe was laid horizontally under river bed, the pressure needed was as high as 12 times the sediment thickness. The fluidization method might be applied in Serang river as shown by the model result. The design of the fluidization system depend on the diameter & distance of perforation, pump capacity, and sediment thickness. Key words : Fluidization, river estuary, navigation channel, accretion
