Understanding River Tributaries and the Cauvery System
The question asks us to identify which of the given rivers is NOT a tributary of the river Cauvery. A tributary is a stream or river that flows into a larger stream or river or a lake. Understanding the major river systems in India and their tributaries is important for geography studies.
Let's examine the options provided and determine their relationship with the Cauvery river.
Analyzing Potential Cauvery Tributaries
We need to check if Hemavati, Arkavati, Indravati, and Amravati are known tributaries that join the main Cauvery river flow.
- Hemavati River: The Hemavati is a significant river in Karnataka, South India. It is well-known to be a major tributary of the Cauvery river. It joins the Cauvery near Krishnarajasagara.
- Arkavati River: The Arkavati is another river originating in Karnataka. It flows towards the east and is also considered a tributary of the Cauvery river, joining it near Kanakapura.
- Indravati River: The Indravati river is a large river originating in Odisha and flowing through Chhattisgarh and Maharashtra before joining another major river. This river is part of a different river basin entirely.
- Amravati River: The Amravati is a river that flows through Tamil Nadu and Kerala. It is a major tributary that joins the Cauvery river in Tamil Nadu.
Identifying the Non-Tributary of Cauvery
Based on our analysis:
- Hemavati is a tributary of Cauvery.
- Arkavati is a tributary of Cauvery.
- Amravati is a tributary of Cauvery.
- Indravati is NOT a tributary of Cauvery. The Indravati river is actually a major tributary of the Godavari river.
Therefore, the river among the options that does NOT flow into the Cauvery river is the Indravati.
| River Name | Is it a Cauvery Tributary? | Parent River (if not Cauvery) |
|---|---|---|
| Hemavati | Yes | Cauvery |
| Arkavati | Yes | Cauvery |
| Indravati | No | Godavari |
| Amravati | Yes | Cauvery |
The question asks for the river that is NOT a tributary of the Cauvery. From the options, Indravati is confirmed to be a tributary of the Godavari river, not the Cauvery.
Conclusion on Cauvery Tributaries
By examining each river listed in the options, we can definitively say that the Indravati river is the one that does not join the Cauvery river system. It belongs to the Godavari river system.

Additional Information about Indian River Systems
Major river systems in India like the Ganga, Brahmaputra, Indus, Godavari, Krishna, and Cauvery are crucial geographical features. They are fed by numerous tributaries, which collect water from vast catchment areas. Understanding the network of these rivers and their tributaries helps in studying regional geography, water resources, and environmental patterns.
The Cauvery River, also known as Kaveri, is a sacred river in South India. It originates in the Brahmagiri Hills of the Western Ghats in Karnataka and flows through Karnataka and Tamil Nadu before draining into the Bay of Bengal.
The Godavari River is the second-longest river in India. It originates in Trimbakeshwar, Maharashtra, and flows east through Maharashtra, Telangana, Andhra Pradesh, Chhattisgarh, and Odisha before emptying into the Bay of Bengal.
