Lecture 24

Question 1

What are the long term changes in total stream flow for glaciers

Answer 1

Will have increased flow at first, then will hit peak flow and reduce after that because glacier will have shrunk a lot by then

Question 2

What can be done to adapt to melting glaciers

Answer 2

Cut carbon emissions to try and prevent climate change, build dams or water storage systems, conserve water

Question 3

Problems that are created by melting glaciers

Answer 3

1. changes in stream flow patterns from glacier melt(short term increase and long term decrease
   2 floods from glacier outburst floods

Question 4

Where does glacial meltwater go?

Answer 4

Channeled into streams and rivers, used for drinking irrigation, power generation etc…

Question 5

Unstable glacial lakes example

Answer 5

Water that collects behind the terminal moraine(proglacial lakes)
Usually unstable and present hazards to nearby people in “outburst floods”

Question 6

What could cause the moraine dam to fail

Answer 6

overfilling, seismic activity, landslides sending a wave

Question 7

Assessing disaster risk

Answer 7

1. Hazard
2. Exposure
3. Vulnerability
