Types of Open Channel Flow
1 Steady Flow
Flow is said to be steady when discharge does not change along the course of the channel flow.
2 Unsteady Flow
Flow is said to be steady when discharge changes with time.
3 Uniform flow
Flow is said to be uniform when both the the depth and discharge is same at any two sections of the channel.
4 Gradually Varied Flow
Flow is said to be gradually varied when ever the depth changes gradually along the channel.
5 Rapidly Varied Flow
Whenever the flow depth changes rapidly along the channel the flow is termed rapidly varied flow.
6 Spatially Varied Flow
Whenever the depth of flow changes gradually due to change in discharge the flow is termed spatially varied flow.
