In an irrigation canal network, the correct hierarchy from main canal to field channel is:
Irrigation EngineeringCanal Distributary SystemMEDIUM
Choose the correct answer
A
Main canal -> Branch canal -> Distributary -> Minor -> Watercourse
B
Distributary -> Branch -> Main -> Minor
C
Main canal -> Watercourse -> Branch -> Minor
D
Branch canal -> Main canal -> Distributary -> Minor
Correct Answer
A. Main canal -> Branch canal -> Distributary -> Minor -> Watercourse
Why is this the answer?
Canal hierarchy: Main canal (off-taking from barrage/dam) -> Branch canals (major off-takes) -> Distributary canals -> Minor canals -> Field channels (watercourses) -> Field application. Outlets (moghas) connect distributaries/minors to watercourses.
