Brahmaputra River System:

1. Brahmaputra is the only river having a masculine name.
2. Brahmaputra which is about 2900 km long is longer than Sindhu but most of its flow is outside India.
3. It originates in Tibet near the origin of Sindhu and Satluj rivers.
4. It is called Tsang Po in Tibet.
5. In Tibet, it flows parallel to Himalayas in the eastern direction.
6. It then takes a ‘U’ turn at the mountain peak called Namcha Barwa and enters India through Arunachal Pradesh. Here, it is known as Dihang.
7. This river, with Dihang, Lohit and Kenula tributaries collectively is known as Brahmaputra in Assam.
8. Brahmaputra is known as Jamuna in Bangladesh.
9. ‘Mazuli’, an island in Brahmaputra, is the largest riverine island in the world.
10. The Tibet part of Brahmaputra contains less sediment.
11. In India, Brahmaputra flows through areas receiving very heavy rainfall and hence, the river carries much alluvium.
12. Many tributaries meet this river in Assam.
13. During monsoon, the total volume of Brahmaputra river water and her tributaries rises greatly causing floods in Assam and Bangladesh.
14. Due to increased sand level of this river at several places its surface gets higher. As a result, there are frequent changes in the course of river.
