Q
Distinctive landscapes
Pembrokeshire
A
- Green bridge of Wales - sea arch

2
Q
Distinctive landscapes
River Tees - reservoir
A
- Water supply
- Hydro-electric power
- Disrupts the natural flow
- Floods habitats

3
Q
Distinctive landscapes
River Tees - Farming
A
- Arable
- Pastoral
- Water pollution through pesticides and other chemicals
4
Q
Distinctive landscapes
River Tees - Industry
A
- Flat mouth land
- Air pollution
- Water pollution
- Noise pollution
5
Q
Distinctive landscapes
River flooding - speed
A
- Drains increase water speed increased flooding chances
- Bare arble land increases water speed
- Vegetation reduces water speed as water gets absorbed by plants
- Trees stop water speed reducing the amount of water in the rivers
6
Q
Distinctive landscapes
River Thames - flooding
A
- 2014
- 5,000 businesses and homes destroyed
- Wettest winter on record - soil fully-saturated
- £500 million in damages
- Thousands evacuated
- Jubilee river is a man-made river designed to take water from the Thames away from important areas such as Eton and Windsor castle however it takes water much more quickly than the Thames so the risk of flooding downstream is much higher.
7
Q
Distinctive landscapes
The Thames Barrier
A
- Protects 1.25 million people

- 10 barriers, 20m tall, 520m across
8
Q

Barking riverside
A
- Houses built with gaps and on concrete slabs
- Houses built on raised land
- Water allowed to spread
- Green corridors to allow water speed to decrease
9
Q
Distinctive landscapes
Ethiopia
A
- Reduced water - droughts
- Reduced harvests

10
Q
Distinctive landscapes
Tuvalu
A
- 5 metres above sea level
- 8,000 still in Tuvalu
- 4,000 migrated to New Zealand
- 3,500 km from Australia

- 600,000 tonnes of shingle taken
- Cliff not protecting the beach
12
Q
Porlock
A
- Managed retreat
- Shingle acted as a natural sea wall
- Shingle was overcome and land behind was flooded
- Longshore drift meant the replacing shingle would move down the beach
- Farmland behind is abandoned and left to flood
13
Q
Minehead
A
- Sea walls and rock armour to protect from the sea
- £12.5 million to protect £21 million in damages
- Protects the tourist economy
14
Q
Geology
Holderness
A
- Soft rock moved by glacial ice
- Soft boulder clay
- Easily erroded
- Strong northerly winds bring powerful destructive waves
15
Q
Holderness
Mappleton
A
- Rock groyne and barrier built here to maintain the beach
- Prevent erosion of the cliff and therefore protect the road
- South of the defences the cliffs are more eroded as there is less material on the beach .
16
Q
Hurricane Katrina
Date and causation
A
- 2005 - New Orleans
- Tropical depression in Bahamas creates tropical winds of 280mph
- Levees broke allowing waves to flood
17
Q

Evacuation + damages
A
- Evacuation to superdome - 15,000 prepared 26,000 arrived
- Told people to drive by cars but 25% of people don’t have cars
- $75 billion in damages
- 1604 dead
- 3 million no electricity
18
Q
El Nino
A
- Weaker E–>W trade winds
- Winds don’t move towards Australia
- Americas recieve more rain - storms
- Less rain to Australia - droughts
19
Q
La Nina
A
- Stronger E–>W trade winds
- Winds move towards Australia
- Australia recieves more rain - flooding
- Americas less rainfall - droughts
20
Q

A
- 2012
- Bewl reservior at 60% - February
