(i) Most of the peninsular rivers are seasonal in nature because their flow is dependent on rainfall.
(ii) Even the large rivers have reduced flow of water in their channels during the dry season.
(iii) Therefore, the peninsular rivers have shorter and shallower course as compared the Himalayan rivers.

The Narmada, the tapi, the Kaveri, the Krishna, the Godavari, the Mahanadi and the pennar.

The river system of an area is termed as drainage

A water divide means the upland which divides the two drainage basins from each other.
Example: Ambala-Saharnpur upland seperates the Indus Basin from the Ganga Basin

Drainage System in India:
Indian river systems are grouped into two main classes. They .are:
(i) The Himalayan rivers and
(ii) The Peninsular rivers.
(A) Himalayan rivers originate from the Himalayan mountains and the Peninsular rivers from the plateau. Hence, the Himalayan and the Peninsular rivers are different from each other. 
(i) The Himalayan rivers are mostly perennial.
(ii) They originate from the north of the mountain ranges.
(iii) They have cut through the mountains making spectacular gorges, due to the upliftment of the mountains and down cutting of rivers simultaneously.
(iv) They perform intensive erosional activities upstream and carry large am of load of sand and silt.
(v) The courses of the Himalayan rivers are very long from their source to the sea.
(vi) Himalayan rivers have large basins.
(vii) In plains they flow forming large meanders due to gentle scope.
(viii) They form numerous depositional features like flood plain, river bluffs and levees.
(ix) They have formed well-developed deltas.
(B) Peninsular rivers are seasonal, because their flow is dependant on rainfall.
(i) During the dry season, even the large rivers have a highly reduced flow of water in their channels.
(ii) These rivers have shorter and shallower courses as compared to their Himalayan counterparts.
(iii) Some of them originate in the Eastern Ghats and flow towards the west. But most of the rivers originate in the Western Gl'mts and flow towards the Bay of Bengal.
