Flashcards in 3 Gorges Dam (hard engineering) Deck (22):
1

Height

600ft

2

Length

1 mile

3

Reservoir

350 miles

4

Cost

$38 billion to build (bad- costs a lot, could have been spent elsewhere) (good- multiplier effect, provides power --> economic growth, flood protection)

5

What does it provide for farmers

Irrigation

6

How many employed

40,000 for 17 years

7

How much shipping can now be moved

50 million tons vs 10 million

8

How much electricity provided from HE

10% of China's electricity (they produce more than all of UK nuclear PPs)

9

Where was flooding stopped

Downstream

10

How many people protected from flooding

50 million (15 million having the risk decreased)

11

Where are water supplies now secure

For the 13 million in Shanghai

12

Why is HEP so good

Clean and no pollution

13

Where will economic growth be boosted

Shanghai and Wuhan

14

How many died in floods 2010

Approx 700 but would have been worse if no dam

15

Where has it increased pollution

In downstream settlements

16

How many sites of interest destroyed

1.2K

17

How many relocated

1.2 million

18

How many towns, villages and factories under water

100 towns, 1.6K villages, 300 factories

19

What has been building up behind the dam

Industrial waste, natural materials, human waste, dirty water

20

Significance of silt downstream

Could lead to sinking of Yangtze Delta- eroded by sea- many flooded risking flooding for many cities including Shanghai

21

Cost of each generator

$50 million

22

What has the reservoir caused

Landslides, earthquakes, more waste and materials into water behind dam
