Drainage System of India: Which river is called the 'Lifeline of South India'?

The Kaveri River is often called the 'Lifeline of South India' due to its crucial role in supporting agriculture, industry, and urban populations across Karnataka and Tamil Nadu. Originating from the Brahmagiri hills in the Western Ghats of Karnataka, the river provides water for irrigation to millions of acres of agricultural land and supports major cities like Bangalore and Chennai through its tributaries and canal systems.
