UPSC CDS-2 – 2019
The Brahmaputra river, known as Tsangpo in Tibet, flows eastward parallel to the main range of the Himalayas. Near the easternmost extent of the Himalayas, it encounters the peak of Namcha Barwa (7782m) in the Tibetan region. At this point, the river takes a sharp U-turn, forming a deep gorge (the Yarlung Tsangpo Grand Canyon), and enters Arunachal Pradesh in India, where it is known as Siang or Dihang, before being joined by other tributaries and becoming the Brahmaputra.
The Brahmaputra (Tsangpo) river makes a significant bend around the peak of Namcha Barwa before entering India.
The other rivers mentioned do not follow this course. The Ganga originates in the Himalayas in Uttarakhand and flows through the plains. The Teesta flows through Sikkim and West Bengal into Bangladesh, joining the Brahmaputra. The Barak River flows through Assam and Manipur into Bangladesh, forming part of the Surma-Meghna river system.
