Groynes are an effective technique because they slow down the process of what occurring?
Transportation
Longshore drift
Nearshore drift
Deposition
How do groynes work to protect the coastline?
They trap sediment by slowing down longshore drift, thereby building up a wide beach
They absorb wave energy so that the cliffs behind are protected
They act as a hard rock barrier at foot of cliff to provide a buffer again the sea
They allow rapid longshore drift along the coastline
What is the main disadvantage of using groynes?
They can starve other beaches of sediment
They prevent longshore drift
There may be too many of them
Which two coastal management structures can you see
Sea wall and gabions
Groyne and rock armour
Gabions and groynes
Sea wall and rock armour
A sea wall is effective because it...
Is not particularly expensive
Stops erosion of the coastline
Deflects wave energy back out to sea
Beach nourishment is .... (choose 2)
when and or shingle is moved from the front to back of the beach by bulldozers
When marram grass is planted to stabilise the beach
A more sustainable form of protecting the coastline
when and sand or shingle is dredged offshore and dumped onto beaches

Which of the following statements does NOT apply to hard engineering coastal management strategies?
A natural approach to managing the coast
Last a short amount of time
Tend to be expensive
Increase erosion further along the coast
Why are coastlines important?
They are a place for people to live and work
They are a habitat for wildlife
They are a place for people to live and work and a habitat for wildlife
What is the main disadvantage of a sea wall?
Aesthetically displeasing
Encourages tourism, and thus litter
Creates strong backwash, causing erosion beneath the wall
Expensive
