Question

What are inundation canals?

Answer 1

These canals r taken out directly from the rivers without constructing any barrages or dam. Such canals use the excess water of rivers at the time of floods and remain operational during rainy season. As the beds of these canals r at the higher level than those of rivers,they get supply of water only when the river is flooded..
therefore it is of limited use....

hope this helps....
