Here, Wales and southwestern England are visible on a rare, cloud-free April day. The River Severn is spilling dark brown sediments towards the Celtic Sea.

The city of Cardiff, Wales, can be seen on its northern shore, and Bristol, England, on its southern shore. The Brecon Beacons mountain range can be seen in Wales, appearing as a brown area not far from the coast.

The River Severn is the longest river in Great Britain, at 220 miles (354 km). With an average discharge of 107 m³/s at Apperley, Gloucestershire, the Severn is England’s greatest river in terms of water flow, and is considered one of the ten major rivers of the United Kingdom.

The river becomes the Severn Estuary after the Second Severn Crossing between Severn Beach, South Gloucestershire and Sudbrook, Monmouthshire.

The river then discharges into the Bristol Channel which in turn discharges into the Celtic Sea and the wider Atlantic Ocean.

The Severn’s drainage basin area is 11,420 square kilometres (4,409 sq mi), excluding the River Wye and Bristol Avon which flow into the Bristol Channel. The major tributaries to the Severn are the Vyrnwy, Teme, Warwickshire Avon and Stour.
