The Brahmaputra River is a transboundary river. With its origin in the Angsi Glacier, located on the northern side of the Himalayas in Burang County of China's Tibet Autonomous Region as the Yarlung Tsangpo River, it flows across southern Tibet to break through the Himalayas in great gorges and into Arunachal Pradesh.
It flows southwest through the Assam Valley as Brahmaputra and south through Bangladesh as the Jamuna.
In the vast Ganges Delta, it merges with the Padma, the main distributary of the Ganges, then the Meghna, before emptying into the Bay of Bengal.
