Coastal management

Cards (26)

  • What does coastal management aim to protect the coast from?
    Erosion and flooding
  • Why is coastal management important?
    To preserve ecosystems and support communities
  • What are the three main types of coastal management strategies?
    Hard engineering, soft engineering, sustainable management
  • How does hard engineering impact natural processes?
    It can disrupt natural processes
  • What is a characteristic of soft engineering strategies?
    Uses natural elements for protection
  • What is the effectiveness of soft engineering methods?
    Effective for natural coastal protection
  • What is a key principle of sustainable coastal management?
    Integration of hard and soft engineering methods
  • What does community involvement in sustainable management aim to achieve?
    Engagement in planning and implementation
  • What are the advantages of a combined approach to coastal management?
    Effective and ecologically sound protection
  • What are the pros and cons of hard engineering methods?
    Pros:
    • Effective at blocking waves
    • Long lifespan
    • Clear line of defense

    Cons:
    • High cost
    • Disrupts natural processes
    • Not aesthetically pleasing
  • What are the pros and cons of soft engineering methods?
    Pros:
    • Environmentally friendly
    • Works with natural processes

    Cons:
    • Can be less reliable
    • Requires maintenance
  • What are the main hard engineering methods used in coastal management?
    1. Sea walls
    2. Groynes
    3. Breakwaters
  • What are the primary protection types in soft engineering methods?
    1. Beach Enhancement
    2. Vegetation-Based
    3. Reef Protection
    4. Managed Retreat
  • How do hard and soft engineering strategies differ in coastal management?
    • Hard Engineering: Physical structures, immediate protection, disrupts nature
    • Soft Engineering: Natural processes, environmentally friendly, less reliable
  • What are the key principles of sustainable coastal management?
    1. Integration of methods
    2. Community involvement
    3. Policy planning
    4. Long-term ecological health
    5. Economic viability
  • What are the advantages and disadvantages of hard engineering compared to soft engineering?
    Hard Engineering:
    • Advantages: Immediate protection
    • Disadvantages: Disrupts natural processes, high cost

    Soft Engineering:
    • Advantages: Environmentally friendly
    • Disadvantages: Less reliable, requires maintenance
  • What is the definition of Beach Nourishment?
    The beach is made wider by using sand and shingle.
  • How does Beach Nourishment increase the distance a wave has to travel?
    It slows down and prevents erosion by increasing the distance a wave has to travel.
  • What is the definition of Managed Retreat?
    Certain areas of the coast are allowed to erode and flood naturally due to their low value.
  • How does Managed Retreat encourage the development of beaches and salt marshes?
    It is low cost and allows natural eroded material to encourage the development of beaches and salt marshes.
  • What is the definition of Beach Stabilization?
    Planting dead trees in the sand to stabilize the beach.
  • How does Beach Stabilization widen the beach and slow down waves?
    It widens the beach therefore slowing down waves and preventing erosion.
  • What is the definition of Dune Regeneration?
    Creating new sand dunes or restoring existing dunes.
  • How do Dunes act as a barrier and absorb wave energy?
    Dunes act as a barrier and absorb wave energy, reducing erosion and protecting against flooding.
  • What is the definition of Afforestation of Coastal Dunes?
    A way to stabilize dunes by planting trees.
  • How does Afforestation of Coastal Dunes minimize sand drift and erosion?
    By stabilizing the dunes, this minimizes sand drift and erosion.
