The 20 questions

  1. What defines hard engineering flood management?

    • Planting native trees
    • Working with nature
    • Allowing natural floods
    • Man-made structures

  2. What defines soft engineering flood management?

    • Building concrete walls
    • Constructing embankments
    • Straightening channels
    • Working with nature

  3. Which of these is an example of hard engineering?

    • River restoration
    • Concrete flood wall
    • Afforestation upstream
    • Flood warning system

  4. Which of these is a classic example of soft engineering?

    • Constructing a dam
    • Dredging the channel
    • Planting trees upstream
    • Building concrete walls

  5. What best defines a benefit of a flood defence scheme?

    • Maintenance fee
    • Construction cost
    • A positive advantage
    • Negative impact

  6. What does a 'cost' mean when evaluating flood defences?

    • Negative impact
    • River water speed
    • Total rainfall amount
    • Only financial profit

  7. Why does planting trees upstream help reduce river flooding?

    • Accelerating surface runoff
    • Interception and absorption
    • Increasing channel depth
    • Evaporating all clouds

  8. Which of these is a typical drawback of hard engineering?

    • Instant biodiversity gain
    • Naturally green look
    • High financial cost
    • Zero flood protection

  9. Which defence suits a quiet village with very low flood risk?

    • Soft engineering
    • Concrete seawall
    • Massive steel dam
    • Deep diversion channel

  10. Which flood defence provides the fastest protection for a town?

    • Afforestation
    • Wetland restoration
    • Tree planting
    • Flood wall

  11. What is the main reason to choose a flood wall over trees for frequent winter floods?

    • Instant protection
    • Natural river aesthetics
    • Lower construction cost
    • Improved wildlife habitats

  12. Which of these is a visual or aesthetic cost of a concrete flood wall?

    • Obstructed river view
    • Enhanced natural scenery
    • Greater tree growth
    • Increased wildlife diversity

  13. What is a major benefit of tree planting as a flood defence?

    • Rapid channel straightening
    • Immediate urban shielding
    • Ecological enhancement
    • Instant concrete barrier

  14. Allowing fields to flood naturally to store excess water is an example of what?

    • Urbanisation
    • Channel channelisation
    • Soft engineering
    • Hard engineering

  15. Which flood defence is an example of hard engineering?

    • Wetland restoration
    • Concrete embankment
    • River meandering
    • Tree planting

  16. Why can building a concrete flood wall cause worse flooding downstream?

    • Increased deposition
    • Lower water volume
    • Faster water speed
    • Slower river flow

  17. Why might a major town choose a wall while a rural village chooses trees?

    • Higher flood risk
    • Cheaper materials
    • Warmer weather
    • Fewer residents

  18. What best distinguishes hard engineering from soft engineering?

    • Lower costs
    • Man-made structures
    • Environmental friendliness
    • Natural processes

  19. Why must councils weigh costs against benefits before choosing flood defences?

    • Eliminate all weather
    • Increase water levels
    • Stop rain permanently
    • Ensure appropriate funding

  20. Which strategy best suits a town with frequent floods and limited funds?

    • Combined approach
    • Concrete dams only
    • No defence at all
    • Relocating the town
