RAP 2: Riverine input of marine litter
One of the major pathways for litter to enter the marine environment is via inland waterways, i.e. rivers and other tributaries. There is limited data about the amount of litter being transported through rivers into the sea. There is also insufficient knowledge about the pathways, sources and transportation mechanisms for litter within rivers, although it is likely to vary greatly, depending on factors such as catchment area and rainfall.
