Il giorno 13 maggio 2026, presso l'aula seminari del dipartimento (palazzina A, 1° piano) si terrà un seminario del Dr. Paula Núñez Pérez, dal titolo "Physical and numerical modelling of transport, dispersion and accumulation of plastic debris in coastal environments".
Abstract Plastic debris constitutes more than 80% of the total marine litter entering the ocean, and its abundance has been rising steadily over recent decades. This increasing load affects not only habitats and ecosystems, but also key socioeconomic sectors such as fisheries and tourism, as well as human health. Anticipating the transport and fate of plastic debris requires a solid understanding of the processes governing its transport, dispersion and accumulation. The transport, dispersion and accumulation of plastic debris in coastal environments are influenced by both hydrodynamic factors (waves, tides, and coastal currents) and the intrinsic properties of the debris (density, size, and shape). Their modelling and prediction are particularly complex within the surf zone, where wave-breaking-induced currents and turbulence are the dominant forces. This seminar provides an overview of recent advances in the transport, dispersion, and accumulation of plastic debris in coastal environments, with a particular focus on the physical and numerical (CFD-Lagrangian) modelling of such processes.
