Kennedy's theory relates to channel design and the concept of critical velocity to prevent scouring and silting.
Kennedy's theory states that the critical velocity (Vc) in a channel is the mean velocity that is sufficient to prevent the channel from scouring and silting (25-Jun-2024). In other words:
- If the actual velocity is greater than Vc, scouring will occur.
- If the actual velocity is less than Vc, silting will occur.
This theory is crucial for designing stable channels that can effectively transport water without degradation due to erosion (scouring) or blockage due to sediment deposition (silting).
