Several major rivers flow eastward across Tamil Nadu from the inland hills toward the Bay of Bengal. These primary waterways include:
- Kaveri (Cauvery) River12
- Ponnaiyar River12
- Palar River12
- Vaigai River12
- Tambraparni (also referred to as Thamirabarani)12
- Vellar2
- Arni2
These rivers are essential to the region's geography, particularly the Kaveri, Vaigai, and Palar rivers, which have formed significant deltas along the eastern coastal lowlands known as the Tamil Nadu Plains.12
