Scouring and erosion
WebScour. The removal of sediment or engineered materials from the bed or banks of a watercourse is known as ‘river scour’ and can occur when the forces imposed by the flow on a sediment particle exceed the stabilising forces (Kirby et al., 2015; Highways Agency, 2006). It is most intense at points where there is a focusing of flow at channel ...

Water erosion also happens along streams or riverbanks when the water flows so powerfully that it picks up chunks of soil along its way.
