The River Avon/ˈeɪvən/ is a river in the southwest of England. To distinguish it from a number of other rivers of the same name, it is often called the Bristol Avon. The name 'Avon' is loaned from an ancestor of the Welsh word afon, meaning 'river'.
The Avon is the 19th longest river in the United Kingdom, at 83 miles (134 km), although there are just 19 miles (31 km) as the crow flies between the source and its mouth in the Severn Estuary. The catchment area is 2,220 square kilometres (860 sq mi).[1]
