Question

Difference between peninsular rivers and himalayan rivers ?

Answer 1

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.

These rivets originate from the lofty Himalayan ranges and are named as the Himalayan rivers.These rivers originate in the Peninsular Plateau and are named as Peninsular rivers.

Answer 2

Indian rivers are divided into Himalayan Rivers and

Peninsular Rivers

i) Most of the Himalayan Rivers are perennial. It means

that they have water throughout

the year. These rivers receive water from rain as well as

from melted snow from the lofty

mountains where as a large number of the peninsular

rivers are seasonal, as their flow is dependent on rainfall.

During the dry season, even the large Peninsular rivers

have

reduced flow of water in their channels.

ii) The Himalayan Rivers have cut through the mountains

making gorges where as

Peninsular rivers do not.

iii) The Himalayan rivers have longer courses from their

source to the sea compared to the Peninsular rivers.

iv) The Himalayan rivers perform intensive erosional

activity in their upper courses and

carry huge loads of silt and sand whereas peninsular rivers

do not.

v) In the middle and the lower courses, the Himalayan

rivers form meanders, oxbow lakes, and many other

depositional features in their floodplains whereas

peninsular rivers do

not.

vi) The Himalayan Rivers have well

-developed deltas.
