Question

Identify the cross-drainage work in the figure.

Correct answer (A) Super passage Solution In the provided diagram, the Drainage / Natural Stream is carried over the Canal . The High Flood Level (HFL) of the drainage is shown above the Full Supply Level (FSL) of the canal. Specifically, the FSL of the canal is below the bed of the drainage stream. This configuration defines a Super Passage . If the canal were above the drainage, it would be an Aqueduct . If the canal were above the drainage and the HFL of the drainage were above the canal bed, it would be a Siphon Aqueduct . If the drainage were above the canal and the FSL of the canal were above the drainage bed, it would be a Siphon Super Passage . Turn this into a strength.
