In this study, a general methodology that is based on numerical models and statistical analysis is developed to assist in the definition of marine litter cleanupand mitigation strategies at an estuarine scale. The methodology includes four main steps: k-means clustering to identify representative metocean scenarios; dynamic downscaling to obtain high-resolution drivers with which to force a transport model; numerical transport modelling to generate a database of potential litter trajectories; and a statistical analysis of this database to obtain probabilities of litter accumulation. The efficacy of this methodology is demonstrated by its application to an estuary along the northern coast of Spain by comparing the numerical results with field data. The necessary criteria to ensure its applicability to any other estuarywere provided. As the main conclusion, the developed methodology successfully assesses the litter distribution in estuaries with minimum computational effort.
