A risk-based approach to prioritise catchments for diffuse metal pollution management

► Diffuse pollution is one of the most challenging issues in catchment management. ► A risk-based approach using a multi-criteria evaluation framework was developed. ► The Humber River Basin District (RBD) in the UK was selected as a case study. ► Catchments at risk of diffuse metal pollution in the Humber RBD were prioritised.
