46.2. Types of Regime

Try these first

1. 1.

   What is an Initial Regime?

   Hint

   Think about which parts of the channel are stable.

2. 2.

   What does the Final Regime ensure?

   Hint

   Consider the stability of both the bed and banks.

3. 3.

   What characterizes an Initial Regime?

   • Both bed and banks are stable
   • Only the bed is stable
   • Neither bed nor banks are stable

   Hint

   Remember the definition of each regime.

4. 4.

   In a Final Regime, what aspects are stable?

   Hint

   Think about what 'final' implies for stability.

5. 5.

   Design a modified channel system that transitions from Initial to Final Regime. What considerations must be taken into account?

   Hint

   Think about balancing flow and sediment supply.

6. 6.

   Evaluate how sudden changes in discharge might impact channels in the Initial Regime versus the Final Regime.

   Hint

   Compare the responses of each regime type to disturbances.
