Beginning in the Himalayas in Tibet as the Tsangpo River, the waterway streams eastbound for 704 miles.

At the Shuomatan Point, the waterway twists and enters India crossing the Assam Valley.

The Brahmaputra enters India in the province of Arunachal Pradesh, where it is called Siang.

It makes an exceptionally fast plunge from its unique stature in Tibet, lastly shows up in the fields, where it is called Dihang.
