Brahmaputra River, Bengali Jamuna, Tibetan Tsangpo, Chinese (Pinyin) Yarlung Zangbo Jiang or (Wade-Giles romanization) Ya-lu-tsang-pu Chiang, major river of Central and South Asia. It flows some 1,800 miles (2,900 km) from its source in the Himalayas to its confluence with the Ganges (Ganga) River, after which the mingled waters of the two rivers empty into the Bay of Bengal.

Along its course the Brahmaputra passes through the TibetAutonomous Region of China, the Indian states of Arunachal Pradeshand Assam, and Bangladesh. For most of its length, the river serves as an important inland waterway. It is not, however, navigable between the mountains of Tibet and the plains of India. In its lower course the river is both a creator and a destroyer—depositing huge quantities of fertile alluvial soil but also causing disastrous and frequent floods.

The Brahmaputra River System

The world’s largest riverine island, Majuli Island is on the Brahmaputra river in the state of Assam. Important cities along Brahmaputra are Dibrugarh, Pasighat, Neamati, Tezpur and Guwahati.

Source of origin: The Brahmaputra river rises from Chemayundung glacier of the Kailash range near the Mansarovar Lake to the north of the Himalayas in the southwest Tibet region.

Confluence or Mouth: The Brahmaputra drains into the Bay of Bengal before forming a huge delta along with the Ganga.
