Question

Which device is used for silt removal after it enters the canal?

(a) Silt Excluder

(b) Silt Ejector

(c) Weir

(d) Barrage

This question was posed to me in an online interview.

I need to ask this question from Diversion Head Works and its Components in section Diversion Head Works, Hydraulic Jump Usefulness in Irrigation Structure of Irrigation Engineering

Answer 1

The correct choice is (b) Silt Ejector

Best explanation: This device can be called as a failsafe device in case the silt excluder does not work properly or the silt charge is beyond the capacity of the silt excluder. This device removes or ejects or extracts the silt which has entered the canal and is thrown out. This device placement is a curative measure and is constructed at some distance from the head regulator.
