Brahmaputra Drainage System
- The Brahmaputra rises in Tibet east of Mansarowar lake very close to the sources of the Indus and the Satluj.
- It is slightly longer than the Indus, and most of its course lies outside India.
- It flows eastwards parallel to the Himalayas.
- On reaching the Namcha Barwa (7757 m), it takes a ‘U’ turn and enters India in Arunachal Pradesh through a gorge.
- Here, it is called the Dihang and it is joined by the Dibang, the Lohit, the Kenula and many other tributaries to form the Brahmaputra in Assam.
- In India it passes through a region of high rainfall. Here the river carries a large volume of water and considerable amount of silt.
- The Brahmaputra has a braided channel in its entire length in Assam and forms many riverine islands.
- Unlike other north Indian rivers the Brahmaputra is marked by huge deposits of silt on its bed causing the river bed to rise.
- The river also shifts its channel frequently.
