Q1:

F.S.L. of a canal at its head with respect to parent channel is kept

A at the same level

B 15 cm lower

C 15 cm higher

D none of these.

ANS:B - 15 cm lower

@M. Indravathi.

See when we take out a canal from a stream or river (parent channel) obviously we have to keep it at a lower level with respect to the parent channel so that water can easily enter into it. If we keep it at a higher elevation then proper entrance of water in the canal can not be achieved.

So, the given answer (B) is correct.
