Peninsula rivers are much older than the Himalayan rivers {Discordant}.
The peninsular drainage is mainly Concordant except for few rivers in the upper peninsular region.
They are non-perennial rivers with a maximum discharge in the rainy season.
The peninsular rivers have reached mature stage {Fluvial Landforms} and have almost reached their base level. [Vertical downcutting is negligible].
The rivers are characterized by broad and shallow valleys.
The river banks have gentle slopes except for a limited tract where faulting forms steep sides.
The main water divide in peninsular rivers is formed by the Western Ghats, which run from north to south close to the western coast.
The velocity of water in the rivers and the load carrying capacity of the streams is low due to low gradient.
Most of the major rivers of the peninsula such as the Mahanadi, the Godavari, the Krishna and the Cauvery flow eastwards and drain into the Bay of Bengal. These rivers make deltas at their mouths.
But the west flowing rivers of Narmada and Tapi as well as those originating from the Western Ghats and falling in the Arabian Sea form estuaries in place of deltas.
There are few places where rivers form superimposed and rejuvenated drainage which are represented by
Examples: The Jog on the Sharvati (289 m), Yenna of Mahabaleshwar (183 m), Sivasamundram on the Cauvery (101 m), Gokak on the Gokak (55 m), Kapildhara (23 m) and Dhuandar (15 m) on the Narmada are the major waterfalls in the Peninsular India
