Management strategies

Question 1

What are the 3 main types of coastal management strategies

Answer 1

Hard engineering
Soft engineering
Integrated sustainable approach

Question 2

What are the main advantages and disadvantages of hard engineering

Answer 2

Very short term effective

Unsustainable in the long term

Question 3

Give 3 examples of hard engineering strategies

Answer 3

1. Sea wall - concrete wall
2. Gabion - rock filled cage
3. Groynes - fences right angle to coast

Question 4

What are the advantages and disadvantages of a sea wall

Answer 4

Long lasting and effective
Prevent flooding and erosion

Can be £5000 per metre (expensive)
Unnatural
If one part of system breaks, it is at risk

Question 5

What are the advantages and disadvantages of gabion’s

Answer 5

Effective and Cheap
Prevent erosion

Ugly and dangerous to birds

Question 6

What are the advantages and disadvantages of groynes

Answer 6

Traps sediment and stops erosion
Cheap

Starve downdraft beaches of sediment
Can rot easily and be dangerous

Question 7

What are the main advantages and disadvantages of soft engineering

Answer 7

Long term effective and sustainable

Take a long time to come into action

Question 8

Give 2 examples of soft engineering strategies

Answer 8

1. Dune regeneration
2. Beach nourishment

Question 9

What are the advantages and disadvantages of dune reservation

Answer 9

Natural and act as a barrier from land and sea, reducing flooding

Can take long to form

Question 10

Give some methods of dune regeneration

Answer 10

1. Replant vulnerable areas
2. Restrict access
3. Selective grazing

Question 11

What are the advantages and disadvantages of beach nourishment

Answer 11

Replacing material to make wider, taller beach, reduces wave energy and erosion

Imported sediments may not react well to environment

Question 12

What are the 2 types of integrated sustainable approaches

Answer 12

SMP
ICZM

Question 13

Give some context for SMP’s

Answer 13

Each UK sediment cell, has a SMP to identify the natural processes and human activities in the area. They are extremely detailed and want to ensure each sediment cell remains a closed system

Question 14

What are the 4 methods of management that SMP’s use

Answer 14

1. Advance the line
2. Hold the line
3. Do nothing
4. Retreat the line

Question 15

Give some context for ICZM’s

Answer 15

Aim to manage the coast as a whole, rather than a sediment cell.
