Uddingston
8 of 57

A floodplain
9 of 57

It is located 34 km west of Glasglow.
10 of 57
What does the River Clyde join towards the end of its course?
The Firth of Clyde which eventually becomes the Irish Sea
11 of 57
Name the case study on flooding in an MEDC?
Carlisle, England
12 of 57
When was Carlisle flooded?
8th January 2005
13 of 57
What River contributed to the flooding of Carlise?
River Eden
14 of 57
How much rainfall fell in Carlisle?
200 mm of rain fell in 36 hours.
15 of 57
What is the geology like Carlisle which resulted to the high discharge of the river Eden?
Carlisle is mainly urban so most materials are made out of impermeable rock which increased surface run off.
16 of 57
What was the discharge of the River Eden as the result of the heavy rainfall?
1520 cumecs
17 of 57
How many people died as the result of the flooding in Carlisle?
3
18 of 57
How many businesses shut down as the result of the flooding in Carlisle?
350 businesses shut down
19 of 57
How many jobs were at risk due to business being afected by the flood?
3000 jobs
20 of 57
How many people were left homeless in Carlisle?
3000
21 of 57
What are 4 flood protection measures Carlisle has introduced?

22 of 57
What did the Eden and Petteril Flood Alleviation Scheme do?
Completed in 2008 which involved the building of flood wall defences and levees
23 of 57
Name the case study on flooding in an LEDC?
Bangladesh, South East Asia
24 of 57
How much rainfall did Bangladesh receive?
900mm of rain fell in July.
25 of 57
Name the rivers which contributed to the flooding in Bangladesh and India?
River Brahmaputra and Ganages
26 of 57
How did the Himalayas contribute to the flooding in Bangladesh?
Melting snow from glaciers increased the discharge in the River Brahmaputra.
27 of 57
What happened to the rivers Brahmaptura and Ganges?
Their peak discharges occurred at the same time, which increased discharge downstream.
28 of 57
How many people die as the result of the Flood in Bangladesh?
2000
29 of 57
How many people were made homeless as the result of the flooding in Bangladesh?
25 million

32 of 57
How many people caught water-born diseases?
100,000 people
33 of 57
How did the flood affect Bangladesh's primary industry?
Price of Basmati rice rose by 10% as fields were flooded.
34 of 57
Name the 3 main ways Bangladesh plan and protect themselves form flooding?
Bangladesh has Flood, Forecasting and Warning System (FFWS) 2. 6000 km of man-made levees 3. Controlled Flooding.
35 of 57
What does the FFWS do?
They have 86 monitoring stations and are able issue flood warnings 72 hours before a flood occurs.
36 of 57
Name the Case Study on Coastal landforms
Dorset Coast line
37 of 57
Give and example of an arch?
Durdle Door
38 of 57
How did Durdle Door form?
erosion by waves opened up a crack in the limestone headland which became a cave and then developed into an arch.
39 of 57
Give and example of a cove?
Lulworth Cove
40 of 57
What types of alternating bands of rock are found in Lulworth?
Soft rock - Clay. Hard Rock - Limestone
41 of 57
What type of coastal landform is Chesil Beach?
Depositional Landform
42 of 57
How was Chesil Beach formed?
Formed by deposition by longshore drift which resulted to the Isle of Portland to be connected to the mainland.
43 of 57
Give an example of a headland and bay?
Swanage bay and Foreland headland
44 of 57
What is the headland made out of in Swanage?
Chalk
45 of 57
What rock is Swanage bay mad eout of?
Sandstone and Clay
46 of 57
What are the Old Harry Rocks?
Old Harry Rocks is the end of a headland in Swanage/Studland that has eroded into a stack.
47 of 57
Name the Case Study on Coastal erosion
Barton- On - Sea
48 of 57
Where is Barton- On - Sea?
Located in Christchurch Bay on the Hampshire Coastline
49 of 57
At what rate are the cliffs of Barton-On-Sea erroding at?
1 metre per year.
50 of 57
What are 4 main effects of erosion on Barton-On-Sea?
1. Regular,large landslides along the stretch of the coastline. 2. Homes by the sea are at risk of collapsing 3. Sections of coastal path are falling 4. Coastal roads have been cracking
51 of 57
What type of rock has been used in rock armour for Barton On Sea?
Carboniferous Limestone
52 of 57
Has rock armour been effective for BOS?
No
53 of 57
Describe a soft engineering coastal management?
Beach replenishment took place in 2007 which cost £3500/m^2
54 of 57
Why were rock groynes built along sections of the beach?
To slow longshore drift and to try and build a wider beach to protect the cliff.
55 of 57
What was the purpose of the drainage basin on BOS?
It was installed within the cliff to prevent rainwater from building up on top of the clay.
56 of 57
What are the 3 problems of the coastal management projects?
1. Hard engineering methods are unsustainable 3. It costs a lot of money to continue to maintain sea defences 3. The geology of the cliff means that will continue to collapse in the future.
