Canals are basically man made waterways. Canals are mostly used for either irrigation purposes or for conveyance/ transportation. Mostly canals are taken out from reservoirs created as a result of building dams. Canals are also carved out from rivers. Canals can be broadly classified in two categories – i) waterways -used for navigation or transportation and ii) Waterducts – used for supply of potable water for irrigation and consumption and other general uses. The article explains about different major canals of India.
