Sustainable Management Of Coasts Flashcards
Explain the problems that a desirable sea view will lead to.
Demand is increased and therefore house prices increase, and many locals can’t afford to buy housing.
This leads to pressure on local landowners, councils and hotels to develop in the coastal area.
This could ruin the natural landscape.
State which types of land use tourism can conflict with
Residential and industrial land use
Give an example of an unsustainable coastal tourist attraction and explain what makes it so problematic.
The Giant’s Causeway, located on the Antrim coast of Northern Ireland, is an unsustainable tourist attraction, because people erode the Giant’s Causeway by walking on the rocks.
This will eventually start to reduce earnings from tourism as the site becomes increasingly unattractive.
Describe the price of roads and railways on the coast as opposed to non-coastal areas.
They cost more to maintain.
Explain how and why industries put pressure on ports.
They pressurise ports to relocate to deeper water, in order to move products faster and more cheaply.
To whom does ship building on coasts present challenges?
Practitioners of integrated coastal management.
Explain the need for coastal defences.
Global warming causes thermal expansion of water, which is predicted to cause a rise in sea level of 48cm by the end of the century.
Sea walls are a coastal management strategy used to do what?
Keep the sea out.
What are sea walls?
Tall concrete walls built at the back of beaches.
How does a sea wall work?
A sea wall’s curved shape deflects the erosive energy of the wave.
It also adds extra protection against waves topping the wall.
Groynes, gabions and beach nourishment/recharging are coastal management strategies used to do what?
Retain cliffs and beaches.
Describe the appearance of groynes.
Groynes are low fences made of hard wood.
They stretch along a beach at intervals of about 50m and point out towards the sea.
How do groynes work?
Groynes slow down longshore drift and promote deposition of sand, which builds up the beach.
What is the disadvantage of groynes?
The wood will eventually break down.
Groynes have a life span of about 20 years.
Describe gabions.
Gabions are metal cages filled with rocks from the local area.
How do gabions work?
Gabions are a short term measure to stabilise cliff bases and absorb wave energy so that the cliffs are not eroded.
What are the two disadvantages of gabions?
- They rust
2. They can be damaged during severe storms.
Explain how beach nourishment/recharging works.
Sand is dredged from the seabed and added to an eroded beach in order to build it up.
Sand may be brought via lorry loads to add extra material along a stretch of a coastline.
What is the disadvantage of beach nourishment/recharging?
Beaches which have underwent beach nourishment erode faster than normal beaches, as the sand is not as tightly packed.

Name a stretch of coastline which can be referred to in an answer about conflicting human activities in the coastal zone.
Limassol coastline
Explain how tourism and industry conflict along the Limassol coastline, and why this is detrimental.
Holiday makers in Limassol become annoyed at the noise pollution which tankers moving in and out of the harbour create.
This can decrease earnings from tourism in Limassol.
Explain how residential use and tourism conflict along the Limassol coastline, and why this is detrimental.
Residents who used to have a clear view of the coastline are now blocked from seeing it as large hotels are being created due to recent boosts in tourism.
This may make residents move elsewhere which may hinder the local economy, especially during non-summer months when there are not so many tourists.
