Question

An irrigation outlet is said to be proportional, when its ______________

(a) Setting = outlet index/ channel index

(b) Setting = channel index/ outlet index

(c) Setting = channel index x outlet index

(d) Setting = channel index + Outlet index

I got this question in an interview for internship.

Query is from Regulation Modules in chapter Regulation Modules and Canal Structure of Irrigation Engineering

Answer 1

Right choice is (a) Setting = outlet index/ channel index

The best explanation: For a proportional outlet H/y i.e. outlet setting should be made and is equal to the outlet index/channel index. It is the ratio of the depth of the sill of a module below the FSL of the distributary to the FS depth of the distributary.
