Abstract: Numerous tools have been used in the past to simulate the transport of plastic particles in marine systems, while less attention has been paid to model plastics’ behavior in fluvial systems. This paper presents the development of a plastic particle tracking model for fluvial settings, with a specific focus on how plastics interact with the channel bed and the free surface. Our Lagrangian transport model captures the movement of individual plastic particles as they interact with the flow field and its boundaries, providing detailed insights into their trajectories. To demonstrate capabilities of the model, we select the Hawkesbury River in Australia as case study.
