Q

Ground water store

A

Where water is stored in porous rocks underground

21
Q

Interception

A

Where trees block raindrops slowing them down before they reach the surface

22
Q

Surface runoff

A

Overland flooding

23
Q

Vertical erosion

A

Erosion of the river bed

24
Q

Lateral erosion

A

Erosion of the river banks

25
Q

Hydraulic action

A

Sheer force causing bed/ banks to erode

26
Q

Abrasion

A

Material by river scraping along the bed and banks

27
Q

Attrition

A

Eroded material carried by river river hitting into each other and breaking into smaller pieces

28
Q

Solution

A

Acids in the water causing erosion

29
Q

River load

A

Material river is carrying

30
Q

Low flow

A

River water levels are low( dry periods)

31
Q

Transportation

A

Movement of material by the river

32
Q

Traction

A

Dragging large boulders along the river bed

33
Q

Saltation

A

Small pebbles and rocks are bounced along river bed

34
Q

Suspension

A

Fine, light particles carried in flow of river

35
Q

Solution

A

Minerals dissolved in river

36
Q

Deposition

A

River dropping material it’s carrying

37
Q

When will a river deposit its load and in what course of the river

A

When it looses energy
Upper course

38
Q

Where might smaller material be deposited

A

Lower course

39
Q

Formation of v- shaped valley and interlocking spur

A
  1. River transports its load
    2.abrasion creates steep sided banks
  2. Banks are unsupported
  3. Banks collapse ( v- shaped valley formed)
  4. If there are areas of harder rock, river will bend around it. (Interlocking spur)
40
Q

Formation of waterfall & gorges

A

Layer of harder rock lays on top of softer rock…
1. Softer begins to erode creating a steep river bed
2. Rock continues to erode and steep drop is created ( waterfall)
3.erosion at the base of the waterfall leads to the beginning of a plunge pool
4. The rocks continue to collapse, deepening the plunge pool below
5. Waterfall retreats leaving a gorge behind

41
Q

What is a meander and what course of the river is it found

A

Bend in a river
Middle or lower course

42
Q

What is an oxbow lake

A

When a meander connects its bends causing the river to redirect leaving an abandoned horseshoe shaped body of water

43
Q

What is a floodplain

A

A large area of flat land that is prone to flooding

44
Q

What is a levee

A

Naturally raised river banks found on either side of a river channel made of gravel and stone

45
Q

What causes flooding

A

Precipitation (rainfall,snow,hail)
Geology (impermeable rocks speed up water flow )
Steep slopes(transfer water quickly)
Sudden snow melt
Urbanisation ( impermeable surface)
Deforestation (no interception)
Agriculture

46
Q

Hydrograph

A

Make one later

47
Q

Hard engineering examples

A

Dams
Channel straightening
Raised embankments
Flood relief channels

48
Q

Soft engineering examples

A

Planting trees
Wetlands & flood storage area
Floodplain zoning
River restoration
Flood warnings & preparation
