The Peninsular drainage system is older than the Himalayan one. This is evident from the broad, largely-graded shallow valleys, and the maturity of the rivers.
Evolution: Three major geological events in the distant past have shaped the present drainage systems of Peninsular India:
The peninsular river system can be categorised into the following sections:
Wondering what is the difference between a delta and an estuary? Let’s see:
A brief account of the major Peninsular river systems is given below:
Smaller rivers flowing Towards the West:
The rivers flowing towards the Arabian Sea have short courses ( Because their origins lie closer to the sea, and the Western Ghats act as a water divide). Several of these small rivers are important for the production of hydroelectricity because of steep slopes and waterfalls.
Small Rivers Flowing towards the East:
There are small rivers which join the Bay of Bengal, though small, these are important in their own right.
