EQ3 Challenges For Costal Landscapes/communities Flashcards
How does costal management effect a coastlines downdrift
Groynes stop sediment from moving down the coast by building it up
How does dredging affect the coastline
It affects the coastline environmentally as it destroys habitats. And it moves unwanted organisms and other objects.
How does industry affect the coastline
Pollution affects the coastline, can destroy habitats
How does development impact the coastline
Pollution of making, impermeable rock light pollution
Why is the sea level rising
Climate change
How bad will the sea level get how will it affect different places
Maldives will be underwater only 1.2 metres above water. Polar ice caps melting
How will climate change affect erosion
Hotter places cause erosion to be more efficient
How does climate change affect storms
More humid weather above bodies of water make storms occur more often
How do groynes and sea walls work
Groynes stop sediment from moving down a beach/coastline. Sea walls act as a barrier against waves they absorb wave energy
How does beach replenishment and slope stabilisation work
Beach replenishment is when sediment is taken from a source and put on a beach that has had LSD occur. Slope stabilisation stabilises slopes using anchored reaction boxes
What is hard and soft engineering
Hard: man made structures, expensive, short term, not sustainable
Soft: less expensive, long term and sustainable, less impact on the environment
Strategic realignment
A way of reducing costal flooding and erosion
