The Rivers of Britain

• short;• most of them flow in eastward

direction;• the water level is always high (due to

humid climate and abundant rainfall);• seldom freeze in winter;• are not navigable for oceans ships;• form deep estuaries; • most of the large ports are situated in

the estuaries.nextback

Estuaries are places where freshwater rivers and streams flow into the ocean, mixing with the seawater.

The Severn

• the longest river in Great Britain, at 354 km (220 miles);

• flows from the Cambrian Mountains in Wales into the Bristol Channel.

Page 6: Inland waters

The Bristol Channel• a major inlet in the island of Great Britain,

separating South Wales from the South West England and extending from the lower estuary of the River Severn to that part of the North Atlantic Ocean known as the Celtic Sea;

• takes its name from the English city of Bristol and is over 50 km across at its widest point.

The Severn Bore is one of Britain's few truly spectacular natural phenomena. It is a large surge wave that can be seen in the estuary of the River Severn, where the tidal range is the 2nd highest in the world.

The two bridges of the Severn crossing carrying roads link Wales with the southern counties of England and are among the most important in Britain:

• Severn Bridge — opened in 1966; • Second Severn Crossing — opened in

1996.

The Tyne

• a river in northern England that flows east to the North Sea;• formed by the confluence of two rivers,

the North Tyne and the South Tyne; • its length is about 100 km.

Page 14: Inland waters

The Trent• one of the major rivers of England; • flows through the Midlands (forming a

boundary between the North and South of England) enters the Humber estuary 65 km from the North Sea;

• its length is 298 km; • one of only two bore rivers in England.

This means that the Trent is tidal, and, like the sea, has a tide twice a day, one in the morning and one in the evening.

The MerseyThe Mersey

A river of northwest England flowing about 113 km (70 miles) generally westward through the southern suburbs of Manchester and emptying into the Irish Sea at Liverpool.

Its large estuary which is 26 km (16 miles) long and 3.2 km (2 miles) wide, is navigable for ocean ships. nexthome

The Lighthouse at New Brighton, also known as the Perch Rock Lighthouse, is situated where the Mersey Estuary opens out into Liverpool Bay.

Before the lighthouse was built there was a wooden ’perch’ erected upon the rock, formerly known as the Black Rock, by the city of Liverpool in 1683. The rock was a serious hazard to navigation. The perch was often washed away by gales. In 1821 one of the Liverpool Pilot Boats crashed into the perch and carried it away.

The construction of the new stone lighthouse started in 1827 and it took 3 years to complete.

The Lighthouse last shone its light in 1973 as it was no longer needed on account of the radar system. Now it is being used as a tourist attraction.

Lakes of the UK• since Britain has a moist climate with much rainfall,

lakes are numerous;• lakes in Scotland are called lochs;• in Northern Ireland they are called loughs;• in Wales a lake is called a Llyn; • many of the largest lakes in England and Wales are

man-made reservoirs or lakes whose size has been increased by damming.

The largest lakes in the UK by country are:

• N. Ireland: Lough Neagh (381.74 km²)• Scotland: Loch Lomond (71.12 km²)• England: Windermere (14.74 km²)• Wales: Lake Vyrnwy (8.24 km²)

The Lake District becomes a picturesque winter scene when snow falls over the hills, creating a white blanket over the fells.
