River Severn Flashcards
source
Plynmilon Hills
the source of the River Severn, in a boggy moorland and starts as a stream
mouth
The River Severns mouth flows into the Bristol estuary
V-shaped valley
in the upper course the river will be eroding mostly downwards. This combined with weathering and mass movement creates v-shaoed valleys with sloping sides.
floodplains
floodplains are areas of flat land that are covered with water during time of flood. They are in the lower and middle courses of the river.
Waterfall
Waterfall in the upper course. It is found where a river flows over a harder rock which doesn’t erode easily, leaving a step that the river flows over.
Waterfall
The Severn-Breaks-its-Neck-Falls in Hafren forest
estuary
at low tide, the river in its estuary is flanked by wide sandy or muddy banks
lower course
Towards the end of the rivers course, the river becomes wider and deeper. The valley is wide and large with a floodplain.
meandering river
In the middle course the river erodes more laterally creating wide valleys and meandering river channels.
The Severn Gorge at Ironbridge
Gorges are created by times of unusually high flow. This gorge was formed towards the end of the Ice Age by the sudden breach of an ice-dammed lake which released an enormous torrent of water and carved a new path of the river through the hills.
middle course
There are meandering streams which leave gravelly banks where the flow of the river is slow.
Severn Estuary at Low Tide
The severn estuary at low tie is flanked by wide sandy or muddy banks.
Human uses of the River Severn
The River Severn was used for food, energy, water and as an essential trade route however it is now being used more for recreation e.g. cruises and fishing.
