Solution
The rivers of the Peninsular Plateau do not originate from mountains; they have their origin in small hills and plateaus. They are not formed by the melting of the snow. Hence, they depend upon rainfall for maintenance of their flow. This is the reason the Deccan rivers are seasonal and not perennial. They dry out in summers and during monsoon, the flow in these rivers increases.
