Which river system includes the Yarlung Tsangpo and empties into the Ganges?

The Brahmaputra is the river system that includes the Yarlung Tsangpo and joins the Ganges.

In Tibet, the upper course is called the Yarlung Tsangpo. It cuts through the Himalayas into Arunachal Pradesh, where it is known as the Siang or Dihang, and then becomes the Brahmaputra in Assam. In Bangladesh, its main channel is called the Jamuna.

The Jamuna meets the Ganges—called the Padma in Bangladesh—and their combined waters later join the Meghna before reaching the Bay of Bengal. Strictly speaking, the Brahmaputra joins the Ganges rather than flowing independently into the sea.

The Salween, Mekong, and Indus are separate Himalayan or trans-Himalayan systems. Another common confusion is the Yamuna, a different Indian river that is a tributary of the Ganges; the Bangladeshi Jamuna is the lower Brahmaputra.
