It’s the second theory mentioned in the section.
3Question 3.
What is the key focus of Kennedy's theory?
- Drainage management
- Critical velocity to prevent silting
- Flood control
Show hintHide hint

- True
- False
Show hintHide hint
Think about Lacey’s approach to sediment management.
Question 5.
If a channel designed using Lacey’s theory experiences a change in sediment type resulting in a larger silt factor, how would this impact the channel design calculations?
Show hintHide hint
Consider how sediment characteristics affect flow.
Question 6.
Evaluate the effectiveness of using Kennedy's theory in modern channel systems, particularly in multi-regional applications. What alterations could be made?
Show hintHide hint
Think about the diversity in modern canal systems.
