Siltation of river beds by fine sediment is a major factor affecting the ecological status of UK rivers. Yet fundamental questions remain relating to the process of siltation and the link with fine sediment delivery to water courses, particularly in the context of agricultural diffuse pollution. CEH has completed a major field based study of siltation in rivers across the UK and this has raised some interesting questions regarding the linkage to sediment inputs. In particular, it is essential to develop a better understanding of the controls on the rates of siltation (e.g. importance of river sediment load versus concentration, effective distance downstream, effect of biota and/or calibre of substrate).
