Rivers can be followed from source, where they begin, to
estuary, where they meet the sea. Along the way they change dramatically.
The River System, Source
to Estuary (B03) has more information about this. The ‘Catchment’
or ‘Drainage Basin’ is the area that affects the river
on this journey, with outputs and inputs along the way altering
the intensity of the waters’ movement, or flow, and the quality
of the water and surrounding environment.

team of Advisors who work in all of the catchments.
If you go to the Fowey
River Journey (L10) you can explore
the Fowey catchment through photographs.
