The 20 questions

  1. What intentional coastal management strategy traps longshore drift sediment to build beaches?

    • Sea walls
    • Groynes
    • Dredging
    • Managed retreat

  2. What unintentional effect can dredging offshore sediment have on coastal erosion rates?

    • Stable accretion
    • Reduced erosion
    • Beach widening
    • Increased erosion

  3. If sediment inputs exceed sediment outputs in a coastal cell, what occurs?

    • Negative budget
    • Dynamic equilibrium
    • Positive budget
    • Sediment deficit

  4. Which process is off-shore dredging directly designed to extract material for?

    • Beach nourishment
    • Dune fencing
    • Cliff stabilisation
    • Saltmarsh creation

  5. Constructing a harbour breakwater most directly interrupts which coastal material flow?

    • Longshore drift
    • Sub-aerial weathering
    • Hydraulic action

  6. If a beach gains 500 m³ of sediment and loses 200 m³, what is its net sediment budget?

    • -700 m³
    • +700 m³
    • +300 m³
    • -300 m³

  7. How does installing groynes typically alter the beach profile up-drift?

    • Steeper and wider
    • Steeper and narrower
    • Flatter and wider
    • Flatter and narrower

  8. What is a major unintentional consequence of building tourist resorts on coastal sand dunes?

    • Saltmarsh expansion

    • Sediment sink

  10. Extending a coastline seawards using artificial hard engineering is known as what?

    • Sub-aerial erosion
    • Coastal retreat
    • Coastal reclamation
    • Managed realignment

  11. What hard engineering structure is built parallel to the shoreline to absorb wave energy?

    • Gabion
    • Offshore breakwater
    • Sea wall
    • Groyne

  12. How do port developments often impact down-drift beaches within the same sediment cell?

    • Increased deposition
    • Dune expansion
    • Sediment accumulation

    • 1,200 m³
    • 2,000 m³
    • 400 m³
    • 800 m³

  14. What is the primary intentional aim of constructing sea walls along coastal towns?

    • Preventing erosion
    • Softening gradients
    • Creating marshes

  15. How does sand removal by dredging affect beach profiles further down-drift?

    • Steeper gradient
    • Wider beach
    • Narrower beach
    • Stable width

  16. Which soft engineering strategy intentionally allows the sea to flood low-lying coastal areas?

    • Rock armour

    • Embryo dunes
    • Offshore bars
    • Wave-cut platforms

  18. In coastal systems, what term describes the movement of energy or material between stores?

    • Output
    • Input
    • Flow
    • Sink

  19. Interrupting longshore drift at one location usually increases erosion where?

    • Onshore
    • Offshore

    • Up-drift

  20. What state is achieved when sediment inputs exactly equal sediment outputs?

    • Dynamic equilibrium
    • Positive surplus
    • Negative balance
    • Mass deficit
