6. Where do rapids occur?

  • Middle course
  • Upper Course
  • Lower course

7. Discharge increases, but so too does?

  • Gradient
  • width & depth
  • size of sediment

8. Where do large floodplains occur?

  • Lower course
  • Middle Course
  • Upper course

9. What effect does a Large Basin Have on river discharge?

  • Peak Discharge will be higher.
  • The water is longer to the main channel
  • The water is quicker to the main channel

10. What is erosion?

  • The wearing away of material from a riverbed and river banks
  • Collisions of particles in the water
  • Perriglacial movement

11. What does a Hjulstrom Graph show?

  • The critical velocity for sediment to be eroded, transported and deposited.
  • The critical discharge levels for sediment to be eroded, transported and deposited.
  • The critical Saltation level for sediment to be eroded, transported and deposited.

12. What are the 4 types of transportation?

  • Traction, Saltation, Suspension & Solution
  • Traction, Saltation, Disintegration and suspension
  • Velocity, discharge, erosion and deposition

13. What is river capacity?

  • The level of discharge before a river will 'burst its banks'
  • Total load a river can transport at a particular energy level
  • The maximum size or weight of material a river can carry

14. What effect does a Small Basin Have on river discharge?

  • Peak discharge will be lowe
  • The water is quicker to the main channel
  • The water is longer to the main channel

15. What is antecedent Moisture?

  • The capacity of groundwater storage
  • The amount of water already in the ground
  • Levels of condensation in the air

16. what is an open system?

  • Allows transfer of energy and mass in and out
  • Allows transfer of energy only
  • Allows transfer of mass only

17. How do porous rocks affect river discharge?

  • Allow water to fill pores, so decrease river discharge
  • Allow water to fill pores, so increase river discharge
  • Have no affect on river discharge

18. What are the processes in the DBH?

  • Evaporation, Water Table, Precipitation, Interception, Surface Run-off, Inflitration, Throughflow, Channel Flow, Percolation, Groundwater Flow, Stem Flow, Drip, Base Flow
  • Evaporation, Water Table, Precipitation, Interception, Surface Run-off, Inflitration, Throughflow, Channel Flow, Stem Flow, Drip, Base Flow
  • Evaporation, Water Table, Precipitation, Interception, Surface Run-off, Inflitration, Throughflow, Channel Flow, Stem Flow, Drip, Percolation

19. What is hydraulic action?

  • The waters movement and its frictional impact
  • Fragments of rock grinding at river bed
  • Collision of particles in water

20. What is V-Shaped and rough?

  • Upper course
  • Lower Course
  • Middle Course
