| Flushing | Sluicing |
| Flushing is done to remove sediment during high flood. | Sluicing is done to remove sediment during plant operation. |
| Intake structure aren’t operational during flushing as water level cannot be maintained. | Intake structures can remain operational during sluicing as water level can be maintained. |
| Outlet discharge is controlled by outlet structure. | Outlet discharge is control by water level. |
| Flushing has retrogressive erosion downstream. | Retrogressive erosion doesn’t occur for sluicing. |
| Flushing is done through bottom outlet. | Sluicing outlet can be provided at any desired height. |
