Understanding Rivers Flowing Through Arunachal Pradesh
Let's analyze the given rivers to determine which of them flow through the state of Arunachal Pradesh in India.
Analysis of the Rivers
We are given three rivers: Barak, Lohit, and Subansiri. We need to check the course of each river.
- Barak River: The Barak River is a major river in North East India. It originates in the Manipur hills. It flows through the states of Manipur, Nagaland, Mizoram, and Assam in India, before entering Bangladesh where it merges with the Surma and Kushiyara rivers to form the Meghna River. Based on its course, the Barak River does not flow through Arunachal Pradesh.
- Lohit River: The Lohit River is a tributary of the Brahmaputra River. It originates in the Zayal Chu range in Tibet, China. It flows through Arunachal Pradesh, particularly in the eastern part of the state, before entering Assam to join the Brahmaputra near Parshuram Kund. So, the Lohit River does flow through Arunachal Pradesh.
- Subansiri River: The Subansiri River is also a tributary of the Brahmaputra River. It originates in the Himalayas in Tibet, China. It flows east and southeast into India, entering Arunachal Pradesh. It then flows through Arunachal Pradesh and Assam before joining the Brahmaputra River in Assam. Thus, the Subansiri River flows through Arunachal Pradesh.
Identifying Rivers in Arunachal Pradesh

Additional Information: Rivers of Northeast India
The rivers of Northeast India are crucial to the region's geography and economy. Many major tributaries of the Brahmaputra River originate in the surrounding hills and mountains, including the Himalayas and Patkai range, and flow through Arunachal Pradesh before joining the main river in Assam.
- The Brahmaputra River itself enters India through Arunachal Pradesh where it is known as the Siang.
- Important tributaries like the Lohit and Subansiri contribute significantly to the volume of the Brahmaputra.
- Other rivers in Arunachal Pradesh include the Kameng, Siang (main Brahmaputra), Dibang, and Manas.
- The Barak River system is distinct from the Brahmaputra system, primarily draining areas further south in the Northeast region before flowing into Bangladesh.
