What is the purpose of a super-passage in irrigation engineering?
DSSSB JE - 2023,
Answer: B
A super-passage is a cross-drainage work in which the canal is taken below the natural stream: the drainage passes over the canal in a trough, so the canal flows beneath it. The opposite arrangement, where the canal is carried over the drainage, is an aqueduct. Crossing at nearly the same level is done by a level crossing, and diverting water from a river into a canal is the function of a headworks or a weir, not of a super-passage.
