Most of the west flowing rivers of Indian peninsula do not form delta. They form estuary. Narmada is one of them. It is so because rocky terrain of the Western Ghats does not allow the rivers to spread out much, and there is not sufficient plain stretch of land between the Arabian Sea and the Western Ghats for the Narmada to slowdown and bifurcates into distributaries. Narmada forms an estuary of 21 km at the Gulf of Khambat. The river is presently partially navigable in the estuary reach around Bharuch but the river has never been a transport artery.

Canal is the second largest source of irrigation providing water to 29.24 percent of the net area under irrigation. The country has one of the world’s largest canal systems stretching over more than one lakh kilometres. Well Irrigation is a principal method of irrigation used in India. Underground water is tapped for drinking purposes and at the same time it is also tapped for irrigating the cultivated land. For implementation of this procedure, a hole is dug in the ground for providing perennial supply of soft water. Well, irrigation is definitely more popular in those regions where groundwater is in plenty and where there are very few canals.

Yarlung Tsangpo is a watercourse that originates at Tamlung Tso lake in western Tibet, southeast of Mount Kailash and Lake Mansarovar. It later forms the South Tibet Valley and Yarlung Tsangpo Grand Canyon, before passing through the state of Arunachal Pradesh, India, where it is known as the Dihang. Downstream from Arunachal Pradesh the river becomes wider and at this point is called the Brahmaputra River. From Assam (India) the river enters Bangladesh at Ramnabazar.
