River Severn
Summary
The River Severn (Afon Hafren, ˈavɔn ˈhavrɛn), at long, is the longest river in Great Britain. It is also the river with the most voluminous flow of water by far in all of England and Wales, with an average flow rate of at Apperley, Gloucestershire. It rises in the Cambrian Mountains in mid Wales, at an altitude of , on the Plynlimon massif, which lies close to the Ceredigion/Powys border near Llanidloes. The river then flows through Shropshire, Worcestershire and Gloucestershire. The county towns of Shrewsbury, Gloucester and Worcester lie on its course.
The Severn's major tributaries are the Vyrnwy, the Tern, the Teme, the Warwickshire Avon, and the Worcestershire Stour.
By convention, the River Severn is usually considered to end, and the Severn Estuary to begin, after the Second Severn Crossing, between Severn Beach in South Gloucestershire and Sudbrook, Monmouthshire. The total area of the Estuary's drainage basin is . That figure excludes the area of the River Wye and the Bristol Avon, both of which flow into the Severn Estuary. The Estuary discharges into the Bristol Channel, which opens into the Celtic Sea and from there into the Atlantic Ocean.
The name Severn is thought to derive from a British *sabrinā, possibly from an older form *samarosina, meaning "land of summertime fallow”.
During the Roman occupation the Severn was known by the Romano-British Latin name Sabrina.
Hafren#In literature
Milton's 1634 masque Comus makes Sabrina a nymph who had drowned in the river.
In Shrewsbury, there is now a statue of Sabrina in the Dingle Gardens at the Quarry, as well as a metal sculpture erected in 2013.
There is a different deity associated with the Severn Estuary: Nodens, represented as mounted on a seahorse, riding on the crest of the Severn bore.
