About Kaveri River

• The river rises on Brahmagiri Hill of the Western Ghats in southwestern Karnataka.
• It flows in a southeasterly direction through the states of Karnataka and Tamil Nadu, and descends the Eastern Ghats in a series of great falls.
• Tributaries: Arkavathi, Hemavathi, Lakshmana Theertha, Shimsa, Kabini and Harangi.
• Before emptying into the Bay of Bengal south of Cuddalore, Tamil Nadu, the river breaks into a large number of distributaries forming a wide delta called the “garden of southern India.”
