Question 1.
What happens to the bed of the channel in the Initial Regime?
Show hintHide hint
Focus on what remains stable in the Initial Regime.
Question 2.
Can the banks of the channel be stable in the Initial Regime?
Show hintHide hint
Remember the definition of Initial Regime.
3Question 3.
What does the term 'Initial Regime' refer to?
- Both bed and banks are stable
- Only bed is stable
- Only banks are stable
Show hintHide hint
Focus on the definition of Initial Regime.
4Question 4.
True or False: In the Initial Regime, sediment transport is entirely stable.
- True
- False
Show hintHide hint
Think about the dynamics of changing conditions.
Question 5.
Calculate how changes in flow velocity due to increased rainfall might affect the width of a channel in the Initial Regime.
Show hintHide hint
Use knowledge of bank erosion and sediment transport to estimate changes.
Question 6.
Analyze how a sudden increase in sediment load due to upstream construction would impact a channel in Initial Regime.
Show hintHide hint
Assess how sediment dynamics interact with flow and bank stability.
