The scenario covers the whole Adriatic Sea, including the sources of marine litter coming from the whole of the Adriatic coastline. The water current transport is simulated by the hydrodynamic model under realistic forcing conditions. The dispersal of marine litter is calculated using a particle tracking model developed to take into account the sinking velocity of the particles, as well as the effect of the bottom rocky sea floor on particle bottom transport. Using this numerical approach, we performed simulations that model the dispersal of marine litter, from which we determined hotspots, where high concentrations of marine litter accumulate. The model results were used to screen for clean-up location, where the concentration of marine litter is high with respect to surrounding areas. A crucial aspect of the model is the characterization of the main sources of marine litter in the Adriatic Sea and in the Gulf of Venice. The public litter represents the first source of beached marine litter followed by non-sourced litter, aquaculture and fishing (mussel nets). In case of macrolitter seabed composition, the main sources are public activity (domestic and touristic waste), followed by shipping activity and fisheries. The macrolitter composition of the seabed is derived from the field surveys in the Gulf of Venice and is very similar to the beached marine litter composition. The data indicates a high spatial heterogeneity of marine litter related to a high variability, both in temporal distribution and abundance of each marine litter type.
