Describe the course of the Brahmaputra River from its source to its mouth
The Brahmaputra River is one of Asia’s longest rivers, flowing for about 2,900 km across Tibet, India, and Bangladesh before draining into the Bay of Bengal.
It rises from the Chemayungdung Glacier in Tibet, where it is known as the Yarlung Tsangpo, and flows eastward for nearly 1,700 km through the Tibetan Plateau, carving deep gorges and receiving several tributaries. Near Namcha Barwa, it makes a sharp southward turn, forming one of the world’s deepest gorges, and enters India through Arunachal Pradesh as the Siang (or Dihang).
On entering Assam, it is joined by major tributaries such as the Dibang, Lohit, and Subansiri, after which it is known as the Brahmaputra. In the Assam Valley, it becomes a wide, braided river, creating extensive alluvial plains and river islands such as Majuli.
Entering Bangladesh as the Jamuna, it merges with the Padma (Ganga) and Meghna rivers and finally empties into the Bay of Bengal, forming the world’s largest delta. Throughout its course, the river carries heavy silt, changes its course frequently, and causes recurring floods
