Which of the following types of canal is classified based on the discharge and its relative importance in a given network of canals?
DSSSB JE - 2023,
Answer: D
The main canal is the type classified by discharge and relative importance in the network. The main canal takes water from the river or reservoir and carries the largest discharge; it feeds branch canals, which feed distributaries and minor canals. Irrigation, navigation and power canals are classified by the purpose they serve (supplying crops, carrying boats, or feeding a hydropower plant), not by size and rank within a network.
