3.2.3.1 Coastal Management

• Protecting coastal communities reduces flood and erosion risks


  True
• Increased storminess can accelerate coastal erosion

  True
• What is a key disadvantage of groynes?

  May cause erosion elsewhere
• What are the two broad categories of coastal management approaches?

  Hard engineering and soft engineering
• What is the primary goal of beach nourishment in coastal management?

  Reduce erosion
• What is a major environmental impact of sea walls on coastal areas?

  Disrupt sediment transport
• What is the main goal of coastal management in the UK?

  Balance people, environment, economy
• Environmental conservation can conflict with coastal development.

  True
• Rising sea levels accelerate coastal erosion.


  True
• Managed realignment may increase flood risk in the short term.


  True
• Beach nourishment reduces erosion by adding sand to beaches.


  True
• Coastal management methods can be categorized into hard and soft engineering
• Soft engineering methods may require ongoing maintenance
• Groynes can lead to beach starvation in other areas
• Coastal management is significant in the UK because the coastline is vulnerable to erosion, flooding, and sea-level rise
• Abrasion occurs when waves carry sand and pebbles that scrape and wear away the coastline
• Order the steps involved in managed realignment:

  1️⃣ Move defenses inland

  2️⃣ Allow coastline to retreat

  3️⃣ Restore natural habitats
• Beach nourishment may be less effective in high-energy coastal environments


  True
• Groynes can cause erosion in other areas.


  True
• Hard engineering methods require ongoing maintenance to remain effective.

  False
• Match the coastal management technique with its environmental impact:

  Beach nourishment ↔️ Restores natural beach environments

  Managed realignment ↔️ Creates new wetland habitats
• Wave erosion is most severe during storms
• Beach nourishment requires ongoing maintenance and sediment sourcing
• Groynes are built perpendicular to the shoreline
• What are the key factors influencing the choice of coastal management method?

  Environment, risk, budget
• Beach nourishment is less disruptive to coastal processes than sea walls.


  True
• What is a negative environmental impact of sea walls?

  Disrupt sediment transport
• Match the environmental impact with the coastal management technique:

  Beach nourishment ↔️ Restores beach environments

  Managed realignment ↔️ Creates new wetland habitats

  Sea walls ↔️ Disrupt sediment transport
• What is a long-term economic benefit of soft engineering methods?

  Enhance tourism
• Order the steps involved in evaluating the effectiveness of coastal management strategies in the UK:

  1️⃣ Compare hard and soft engineering

  2️⃣ Analyze environmental impacts

  3️⃣ Consider economic costs
• What is one environmental advantage of soft engineering approaches in coastal management?

  Less disruptive to processes
• What is a key challenge of traditional coastal management approaches?

  Damage to ecosystems
• What is one benefit of protecting coastal communities through coastal management?

  Reduced flood and erosion risks
• Rising sea levels, increased storminess, and human activities accelerate coastal erosion
• Groynes can stabilize beaches but may cause erosion in other areas.


  True
• Hard engineering provides immediate protection but can be costly and disruptive, while soft engineering is more environmentally-friendly but may require ongoing maintenance.


  True
• What are the two main categories of coastal management approaches?

  Hard and soft engineering
• Which coastal management technique restores natural beach environments and is less disruptive to coastal processes?

  Soft engineering
• What are the three main considerations in analyzing the economic implications of coastal management policies?

  Costs, benefits, trade-offs
• What is one economic benefit of soft engineering coastal management techniques?
