Question

Which is an irigation structure construct across a canal to lower down its water level and destroy surplus?

Answer 1

hey user here is ur answer!!!!!!!

A canal fall is a hydraulic structure constructed across a canal to lower down its water level. This is achieved by negotiating the change in bed elevation of the canal necessitated by difference in ground slope and canal slope.

The necessity of a fall arises when the available ground slope exceeds the design bed slope of the canal and which condition is rather usual. Thus, an irrigation channel which is in cutting in its head reach soon meets a condition when it has to be entirely in filling.
