INDIAN GEOGRAPHY

Detailed explanation-1: -Canal irrigation is the most important form of irrigation in North India. Canals maintain its flow of water throughout the year even during the winter season and draw their water either from rivers or from the reservoir of the river projects.

Detailed explanation-2: -Canal irrigation is adequate in the Northern Plains because the soil in this area is permeable and the level of groundwater is high. Canals in the northern plain of India are built near the rivers for effortless transportation of water everywhere .

Detailed explanation-3: -Canal irrigation is one of the most important sources of irrigation for farmlands across India. It accounts for nearly 24% of the total irrigated land in the country. This effective source of irrigation has greatly benefited deep fertile soil, low-level relief, and perennial river areas.

Detailed explanation-4: -If we look at irrigation in India we can see that about 70 percent of the total irrigation is covered by tube wells and canals.-Regions which have large plains, fertile soils and perennial rivers are irrigated by canals, which is the second most important source of irrigation in India after tubewells.

Detailed explanation-5: -Perennial Canals are those which are taken off from perennial rivers by constructing a barrage across the river. Most of the canals in India are perennial. Merits: Most of the canals provide perennial irrigation and supply water as and when needed.
