Why are peninsular rivers of india are mostly seasonal in nature?
Answers
Peninsular Rivers :-
The major rivers of the peninsular region are Mahanadi, Krishna, Godavari, Tapi, Narmada are Kaveri, Luni etc. All these rivers are seasonal in nature. The reason behind that are as follows.
1) The peninsular rivers are rain fed and depend only on rain water. These rivers do not get continuous water supply from glaciers. Hence most of the rivers dry up in hot summer season.
2) These rivers have small basins and catchment areas. The Godavari has the largest catchment area of 3.12 lakh square kilometer only, which is less than one-third of of the Indus river. So, the peninsular rivers have much less catchment area. This is also the reason that the peninsular rivers are seasonal in nature.
3) The peninsular rivers lie in medium to low rainfall regions when compared to Himalayan rivers, so they receive less rain water in the monsoon season. That is why they are seasonal in nature.
4) The peninsular rivers have short and shallow courses when compared to Himalayan rivers, so they are seasonal in nature.
