The correct answer is option (c) Both (a) & (b).
Explanation:
- In a Barrage the maximum ponding of water is achieved by the crest and lowering the gates.
- Barrage is a structure that is similar to the weir.
- But the only difference is that the crest is kept at a low level and ponding of water is accomplished mainly employing gates.
- As per the above, we can say option (c) i.e Both a and b is correct. That is (a) The crest and (b) Lowering the gates.
