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
