Brahmaputra River
- The Brahmaputra (Son of Brahama) also known as Trans-Boundary river, rises in Tibet east of Mansarowar Lake very close to the sources of the Indus and the Sutlej.
- 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.
- In Arunachal Pradesh, it is called the Dihang and it is joined by the Dibang, the Lohit, and many other tributaries to form the Brahmaputra in Assam.
- Brahmaputra is known as the Tsang Po in Tibet and Jamuna in Bangladesh.
- It is also called International River as it passes through 3 countries i.e. Tibet, India & Bangladesh.
- World’s largest riverine was formed by Brahmaputra in Assam.
River Basin
1. The Brahmaputra basin drains 651,334 km2, Kanchenjunga (8,586 m) is the only peak above 8,000 m, hence is the highest point within the Brahmaputra basin.
2. It is a good example of a braided river and meanders quite a bit and frequently forms temporary sand bars.
3. The hydrology of the Brahmaputra River is signified with its rates of sediment discharge, the large and variable flows, along with its rapid channel aggradations and accelerated rates of basin denudation.
4. The climate in Bhutan, located entirely in the Brahmaputra river basin, is cold in the north, with year-round snow on the main Himalayan summits, temperate in the inner Himalayan valleys of the southern and central regions, and humid and subtropical in the southern plains and foothills.
History of Brahmaputra River
The Tibetans believe that long before human occupation, the Chang Tan plateau was covered by the waters of a great lake. A Bodhisattva (an enlightened being) decided that the waters had to flow in order to help the people in the region. So, he cut an outlet through the Himalayas for the Tsangpo or ‘Great River’.
The mountains, gorges, and jungles through which the Tsangpo flows in Tibet are considered extremely holy. Ancient Tibetan scrolls written by sages, speak of sanctuaries or beyuls deep in the Himalayas. Here, ageing is slowed down and, animals and plants have miraculous powers. The Tibetans believe that in this area, perhaps through one of the waterfalls at the bottom of the world’s deepest gorge, is the doorway to paradise on Earth, Shangri-la.
