Longest Rivers In The United Kingdom (Great Britain)

Great Britain's Severn River flows for 220 miles between its source in the Welsh highlands and its mouth near Bristol, England.

The United Kingdom has several major rivers passing through its cities, towns, and rural landscapes. Most of these rivers drain watersheds from these areas and join several estuaries which empty into the North Sea, Irish Sea, Bristol Channel, and the English Channel. Rivers play important roles in the UK including transportation of human and goods across cities and towns, major sources of water for households and industries, a source of hydroelectric power, and an important habitat for some of the UK’s indigenous wildlife. The rivers are also famous for the sporting activities including canoeing, boat racing, and sailing. The longest rivers in Great Britain are looked at below.

Conservation of Rivers in the United Kingdom

Rivers in the United Kingdom have long been under intense pressures from pollution, climate change, water extraction, and other detrimental human activities. Due to these negative factors, several conservation measures have been put in place to safeguard the rivers. These measures include the UK Rivers Network which aims to mobilize the communities to identify with the rivers and take part in the conservation efforts. Companies have also been challenged to treat and safely dispose waste away from water bodies.
