Brahmaputra River System

Brahmaputra is the one among the mightiest rivers of Asia. It is a transboundary river. River

Brahmaputra is called Yarlung Transpo in Tibet. It emerges from Angsi Glacier,on the northern side of

the Himalayas in Burang County in south western part of Tibet Autonomous Region (TAR) at an altitude

of 4877 m. it flows, through southern Tibet in easterly direction for a longer length, at an average height

of 4000 m. at its easternmost point, the river bends around Mount Namcha Barwa and forms the

Yarlung Tsangpo Canyon. The total length of Brahmaputra River is 2906 km and the river drains an area

of 580000 sq km. River Brahmaputra makes very rapid descent from its origin in Tibet and after

travelling a distance of 1625 km, enters India in the state of Auranchal Pradesh at Mechuka at an

elevation of 660 m. it is known as Siang in the upper and Dihang in lower reaches in Arunachal Pradesh.

It flows from left at Kobo, Assam. Afterwards,it enters Assam and called Brahmaputra. Its width expands

in plains and becomes as wide as 10 km. it is joined by Subansiri in Lakhimpur District of from right and

Kameng (Jia Bharali) in Sonitpur District of Assam. At Tekeliphuta, in Lakhimpur District, Brahmaputra,

River bifurcates into channels- the northern Kherkutia Suti (ultimately joins Subansiri River) and

southern channel ( main Brahmaputra River). Brahmaputra River is rejoined by bifurcated channel

(Subansiri) at Bedetighat at a distance of about 100 km from Tekeliphuta to from the world’s largest

inhabitated river island Majuli.
