Flashcards in 3 Physical Landscapes (river keywords) Deck (36):
The erosion of a surface caused by rock carried by the river scraping off the river bed.
Process where rocks and stones move along in the water and get knocked into one another and are gradually worn away into smaller rounded pieces.
Side-to-side cross section of a river.
The quantity of water that passes a given point on a stream or river bank with a given period of time.
To wear away rock.
The force of the river against the banks can cause air to be trapped in cracks and crevices. The pressure weakens the banks and gradually wears it away.
Sideways erosion by a river on the outside of a meander channel. It eventually leads to the widening of the valley and contributes to the formation of a floodplain.
The end of a river. Usually where it meets the sea.
Particles bouncing down the river bed.
Soluble particles dissolved into the river.
The start of the river.
Fine, solid material held in the water while the water is moving.
The rolling of boulders and pebbles along the river bed.
River picks up and carries material as they flow downstream.
A stream or river that flows into a larger stream or river.
As the river flows downhill, it uses energy to overcomes friction which causes the river to erode downwards.
When the water loses energy, it drops the rock particles down the stream or on the river bank.
The gradient of a river from source to its mouth.
A bend in a river.
A term used to describe the shape of land.
An area of land that is draining a river and its tributaries.
Flat areas that flood.
Natural embankments along the edges of a river channel.
Tidal areas where the river meets the sea (mouth).
Man-made structures built to control the flow of rivers and reduce flooding.
Schemes set up using knowledge of a river and it’s processes to reduce the effects of flooding.
Flood relief channels
Channels are built that divert water around important areas.
Dams and reservoirs
Huge walls built across rivers usually in the upper course.
River course straightened, artificially straight channels.
Raised walls built along river banks.
Making the river more natural.
Flood plain zoning
Prevent building on floodplains.
