Arunachal Pradesh
Arunachal Pradesh.
The major river system in Arunachal Pradesh is the Brahmaputra, which is known as the Dihang (or Siang) within the state. It flows from the Himalayas and winds southward through the mountainous terrain before reaching the Assam plains.1
Several significant tributaries also flow through the state, including:1
- Dibang (Sikang)1
- Lohit1
- Subansiri1
- Kameng1
- Tirap1
While the Brahmaputra and the Subansiri cross the main Himalayan ranges, other rivers like the Kameng originate on the southern flanks of the mountains. The Tirap River specifically serves to drain the southeastern region of the state.1
