Discuss the significant difference between the Himalayan and the Peninsular Rivers.
Share
The following table differentiates between the Himalayan and the Peninsular Rivers:
The Himalayan Rivers
1. The Himalayan rivers rise in the snow-covered mountains are perennial type.
2. They flow in levelled Northern Plains and are highly useful for irrigation, cultivation and also navigation purpose.
3. The Himalayan Rivers bring with them fertile alluvium which they deposit in the Indo-Gangetic plains.
4. Canals have been dug to use the water of these rivers for irrigation.
5. Many important towns and centers of trade are situated on the banks of these rivers.
6. The porous soil of Northern Plain absorbs the water which is later on used as ground water by digging wells and tube wells.
The Peninsular Rivers
1. The mountains in which the Peninsular Rivers rise not snow covered. Hence they dry up during summer.
2. The Peninsular Rivers flow on rocky surface and so, they are neither navigable nor useful for irrigation.
3. They do not bring with them any alluvium. Due to their swift current the depositional activity are negligible.
4. as the terrains are rocky and the banks of these rivers are high so, canals can not be dug. However, dams are built to store the flood water for irrigation with the help of small channels.
5. Very few important towns and centers of trade are situated on the banks of these rivers.
6. The underlying soil being rocky does not absorb any water. Hence, no wells can be dug.

The significant differences between Himalayan and Peninsular rivers are:
– Origin: Himalayan rivers arise from the Himalayas due to snowmelt and glaciers, while Peninsular rivers emerge from the plateau due to rainfall.
– Course: Himalayan rivers have steep gradients and swift flows, while Peninsular rivers display gentler gradients and slower flows.
– Seasonal Flow: Himalayan rivers show significant seasonal variations, whereas Peninsular rivers have comparatively consistent flows.
– Drainage Pattern: Himalayan rivers exhibit dendritic patterns, while Peninsular rivers feature radial or trellis patterns.
