The rivers of India can be classified into four groups – Himalayan, Deccan, Coastal, and Inland drainage.
The Narmada and Tapti rivers originate from the Vindhya and Satpura ranges in Central India.
[4] In the peninsular India, majority of the rivers originate from the Western Ghats and flow towards the Bay of Bengal, while only a few rivers flow from east to west from the Eastern Ghats to the Arabian sea.
This is because of the difference in elevation of the Deccan plateau, which slopes gently from the west to the east.
[6] The major peninsular rivers include the Godavari, the Krishna, the Mahanadi and the Kaveri.
