Drainage


The Brahmaputra River System


The Brahmaputra rises in Tibet east of Mansarovar Lake very close to the source of Indus and Sutlej.

It flows eastward parallel to the Himalayas. On reaching Namcha Barwa (7757 meters), it takes a U turn and enters India in Arunachal Pradesh through a gorge.

Here it is called the Dihang.

The Dibang, the Lohit and many other tributaries join the Dihang to form the Brahmaputra in Assam.

InTibett, the river carries a small volume of water and less tilt as it is a cold and dry area.

In India, it passes through a region of high rainfall. Here, the river carries a large volume of water and a considerable amount of silt.

The Brahmaputra has a braided channel in its entire length in Assam and forms many riverine islands.

It causes widespread devastation due to floods in Assam and Bangladesh.

Unlike the other Indian rivers of North, this river is marked by huge deposits of silt on its bed causing the river bed to rise.

The river also shifts its channel frequently.
