Question

Pipe sluices are generally not adopted in tank bunds where the depth below F.T.L exceeds ____________

(a) 1.5 m

(b) 1 m

(c) 2.5 m

(d) 5 m

I had been asked this question in a national level competition.

Question is from Tank or Surplus Escape Weirs Design topic in division River Navigation & Tank Irrigation of Irrigation Engineering

Answer 1

The correct choice is (c) 2.5 m

The best explanation: Pipe sluices are earthenware or cement or cast iron pipes which may be used in place of masonry culverts in case of very small slices. The earthenware pipes may get fractured or leakage through their joints may take place resulting in a breach. The pipes can neither be examined nor repaired easily without cutting open the bund. They are not adopted when the depth below F.T.L exceeds 2.5 m or so.
