The 20 questions

  1. What is the primary characteristic of hard coastal engineering?

    • Dynamic systems
    • Biological habitats
    • Natural processes
    • Man-made structures

  2. What coastal management approach works with nature using methods like beach nourishment?

    • Soft engineering
    • Managed alignment
    • Hard engineering
    • Coastal retreat

  3. How does a curved sea wall primarily protect the coastline?

    • Absorbing sand
    • Reflecting waves
    • Sinking ships
    • Trapping silt

  4. What material is trapped by coastal groynes?

    • Sand
    • Magma
    • Lava
    • Clay

  5. What is rock armour also known as?

    • Sea wall
    • Gabions
    • Groynes
    • Rip-rap

  6. What process involves adding new sand or shingle to a beach?

    • Beach nourishment
    • Managed retreat
    • Cliff regrading
    • Dune stabilization

  7. What strategy involves allowing low-value land to flood naturally?

    • Managed retreat
    • Hard stabilization
    • Sea wall construction
    • Coastal zoning

  8. Which coastal management approach is typically cheaper?

    • Steel piling
    • Soft engineering
    • Concrete barriers
    • Hard engineering

  9. A council builds a concrete wall with a curve that bounces waves back. Is this hard or soft engineering?

    • Hard engineering
    • Soft engineering
    • Beach nourishment
    • Managed retreat

  10. Pumping new sand onto an eroded beach is an example of what?

    • Rock armour
    • Groynes
    • Sea wall
    • Beach nourishment

  11. A council gives back low-value farmland to the sea. What is this called?

    • Managed retreat
    • Rock armour
    • Hard engineering
    • Groyne building

  12. Why does sand accumulate on one side of a groyne?

    • Attracts wind
    • Blocks longshore drift
    • Increases tides
    • Creates rip currents

  13. What is the main function of rock armour placed at cliff bases?

    • Speeds up erosion
    • Removes sand
    • Breaks wave energy
    • Increases rainfall

  14. What is a major disadvantage of constructing large sea walls?

    • Natural appearance
    • High cost
    • Rapid decomposition
    • Zero protection

  15. Which defence strategy provides a natural look at a lower cost?

    • Offshore breakwater
    • Concrete sea wall
    • Steel groynes
    • Beach nourishment

  16. Why must beach nourishment be repeated periodically as a soft engineering strategy?

    • Waves wash sand away
    • Sand dissolves in saltwater
    • Plants consume the sediment
    • Visitors steal the sand

  17. What negative impact can a groyne have further down the coast?

    • Starves down-drift beaches
    • Floods inland towns
    • Dries up rivers
    • Creates volcanic ash

  18. Which factor is most important when deciding whether managed retreat is fair?

    • Cost versus value
    • Tourism revenue only
    • Historical age alone
    • Total population size

  19. Why are expensive hard engineering defences usually built around cities rather than farmland?

    • Stronger wave action
    • High land value
    • Deep water depth
    • Low construction cost

  20. What is a major disadvantage of building a concrete sea wall?

    • Increased beach size
    • High cost
    • Lower wave energy
    • Zero protection
