4.5 Challenges For Coastlines Flashcards
Why is sea level rising?
The melting of land glaciers
The average temperature of sea rising eg meaning expansion
The green house effect.
How bad will sea level get?
If it went up by around 25M it would destroy most of the Maldives and Bangladesh and not much else.
By a bit more and the UK and other coastal countries will start to lose a lot of land to the sea.
Climate change to erosion?
It will mean that structures will change and coastlines will change drastically as well.
Groynes and sea walls?
Groynes will stop LSD from taking place and the sea wall will stop sea levels flooding onto the land.
Hard engineering?
The large amounts of man-made materials such as concrete. They aim to stop natural processes such as LSD, erosion. They typically involve large scale construction and disruptions.
Soft engineering.
Uses nature to work with the engineering, they try to use natural and non-harming materials. It does not have a lot of construction and it needs some maintenance.
What are the different ways to protect the coastline?
Offensive- you go forward getting more land.
Defences- blocks the erosion taking place on the coastline eg sea walls.
Strategic realignment- protect some places and let others erode.
Why does the UK use ITCM strategy?
Not enough money to do all of the coast and need to protect the most important areas of land eg tourism, industry and more.
How will storms affect us?
Storms will be getting more unpredictable and will become more dangerous as climate change carries on.
Why is agriculture the lowest income?
It is due to cattle being a low income job which means that it is not important land to protect
Things about attacking the coast.
Advantages: you will get more land from this, not the most expensive thing to maintain.
Disadvantages: the land will not get higher meaning one massive storm could destroy it.
Things about strategic realignment.
Advantages: protect the coast with not using all your money, the high income areas will be saved.
Disadvantage: some places will not be able to be saved from erosion and it will be where there is low income (agriculture nature reserves).
Climate change and deposition.
Some places will start to get less deposition than before and other places sill get more than before.
Why are the land glaciers melting going to the sea?
The water will find away to the sea due to it what water does.
Why is climate change happening?
Due to the green house effect which gets trapped in our atmosphere and will heat up our planet.
