“…Figure 5 shows the positions of small objects with negligible mass at 2000s, 4000s and 6000s after they are released at the inflow section. These are the results for the discharge of 1000m 3 Figure 3. Since the particles in these cases are assumed very small they indicate the Lagrangian trajectories of the surface flow.…”

In order to study and understand the characteristics of transport and depositions of floating objects in real rivers, Large Eddy Simulation (LES) method of real river flows with complex bathymetry, the riparian vegetation and the floating objects has been developed and applied to a meandering river in Perak, Malaysia. The movement and accumulation of floating objects are different for different sizes and the shapes of the objects. The vegetation that may exists on the bed and the banks also are seen to influence the positions where the objects are accumulated and deposited. The results can be used to control the increasing amount of solid objects washed into the rivers and to the ocean.

“…In order to control the movement and accumulation of discarded objects, the present authors simulated the transport and accumulation of floating objects in a large river in Malaysia [3]. The motion of floating objects in rivers is limited by the banks and they mostly follow the river flow itself.…”
