Q

Why is Japan prone to earthquakes?

A

The Philippine and Pacific plates are rapidly moving towards the larger Eurasian and North American plates - up to 8 cm a year, which causes a lot of frictional energy to build up over time.

21
Q

What were the causes of the 2014 Somerset Levels Floods?

A

There was the highest record of annual rainfall since 1910 - 350mm, 100mm above average. High tides and storm surges pushed water upstream from the Bristol Channel, and the rivers had not been dredged for at least 20 years, leaving them clogged with sediment.

- Logging and farming creates jobs for the people
- Brazil exported $28bn worth of metals in 2018
- Soil erosion in the forest region

- Overcultivation reduces quality of soil
- Deforestation on desert fringes for fuel
- Population pressure causes overgrazing, overcultivation and deforestation
- Soil erosion caused by a lack of vegetation holding it together

31
Q

What are 3 management strategies to reduce desertification in the Sahara Desert?

A

Management strategies include:
- Ponding banks to store water
- Contour traps to prevent soil being washed out during heavy rain
- Planting trees to bind the soil together and reduce erosion
- Giving areas national park status to give the area legal protection and investment
- Irrigation management to prevent salinisation

34
Q

Where is Lyme Regis situated?

A

Lyme Regis is located on the south coast of England, in west Dorset.

35
Q

Why does Lyme Regis need coastal management?

A

Lyme Regis needs coastal management because the town was built on unstable cliffs, and the coastline is eroding rapidly due to powerful waves from the south-west, causing much damage to the properties there.

36
Q

When was Phase 1 of the Lyme Regis Coastal Management Scheme and what did it entail?

A

Phase 1 was initiated in 1990 and mainly completed in 1995. It:
- Constructed a new sea wall and promenade East of the mouth of the River Lynn
- In 2003-2004, the cliffs were stabilised as a part of an emergency project, held together by large nails, which totalled £1.4 million
- Drainage was improved and the beach profile was re-sloped

37
Q

When was Phase 2 of the Lyme Regis Coastal Management Scheme and what did it entail?

A

Phase 2 started in 2005 and completed in 2007, costing a total of £22 million:
- New sea walls and promenades were constructed
- A wide sand and shingle beach was constructed to absorb energy from the waves - the sand was imported from France
- Rock armour was extended at The Cobb, to help protect the bay and fishing boats behind it

38
Q

What happened to Phase 3 of the Lyme Regis Coastal Management Scheme?

A

It was not undertaken. They determined the cost of the scheme outweighed the benefits.

39
Q

When was Phase 4 of the Lyme Regis Coastal Management Scheme and what did it entail?

A

Phase 4 started in 2013 and finished in 2015, totalling £20 million:
- Another 390m sea wall was constructed in front of the existing wall for additional support
- More nailing, draining and stabilising of the cliffs to protect over 480 homes

40
Q

What were some of the positives of the Lyme Regis Coastal Management Scheme? Give two details.

A

Some of the positives of the scheme included:
- Increased number of tourists bringing wealth and jobs
- Defended the coast against stormy winters
- Better protected harbours benefit boat owners and fishermen

41
Q

What were some of the negatives of the Lyme Regis Coastal Management Scheme? Give two details.

A

Some of the negatives of the scheme included:
- Increased tourists leading to conflict between the locals who think congestion and litter have increased
- Some people think the defences spoilt the natural landscape
- The sea wall interferes with the coastal processes in the neighbouring coastlines, causing conflicts elsewhere
- Stabilising cliffs means that no fossils will get revealed in landslides, a potential conflict of interest within certain groups

42
Q

Where is Banbury located?

A

Banbury is located around 30km north of Oxford, on the floodplain on the River Cherwell (a tributary to the Thames)

43
Q

Why did Banbury need river management?

A

Banbury had a history of flooding but in 1998 a massive flood forced the closing of its railway, shut down roads and caused £12.5 million worth of damage, then in 2007 was flooded again.

44
Q

What did the 2012 Banbury flood defence scheme do to help reduce damage from flooding? Give 3 details.

A

Methods include:
- 2.9km embankment built parallel to the M40
- Flood storage area created capable of storing 3 million cubic metres of water located on the floodplain of the River Cherwell
- A361 road raised + drainage improvements beneath the road
- Extra earth embankments and floodwalls to protect properties
- A pumping station to transfer excess rainwater to below the town
- The Biodiversity Action Plan (BAP) created new ponds, trees and hedges to help make the soil more absorbent and store excess water

45
Q

Give 2 social effects of the Banbury flood defence scheme.

A

Social effects include:
- The raised A361 route will be open during floods, no longer disrupting people’s lives
- Quality of life for local people will increase with the increased green spaces and footpaths
- Reduced stress and anxiety through the fear of flooding and the damages associated with it

46
Q

Give 2 economic effects of the Banbury flood defence scheme.

A

Economic effects include:
- The entire scheme cost around £18.5 million
- Donors included the Environment Agency and Cherwell District Council
- Benefits estimated at around £100 million saved by protecting 441 houses and 73 businesses

47
Q

Give 2 environmental effects of the Banbury flood defence scheme.

A

Environmental effects include:
- 100,000 tonnes of soil was transferred from nearby to build the embankment, forming a small reservoir
- The BAP was created, increasing the amount of plant and animal life in the area
- Part of the floodplain can now be deliberately allowed to flood if river levels are too high
