Which of the following statement(s) is/are correct
(A). In designing field channels, the flow is considered to be uniform at the maximum discharge.
(B). Flows in lined irrigation channel tend to be steady.
(C). Flows in lined irrigation channel tends to be steady and uniform.
(D). In a channel of changing cross-section, the flow is non-uniform.
Choose the correct answer from the options given below:
Show Hint
To analyze open channel flow types:
- Constant cross-section + Constant discharge \(\rightarrow\) Uniform flow.
- Changing cross-section \(\rightarrow\) Non-uniform (varied) flow (since area \(A\) changes, velocity \(V\) must change spatially).
- Constant parameters with time \(\rightarrow\) Steady flow.
