ISS Previous Year Paper 2016 GS Solution

Q.2(e) What are the differences between Himalayan and Peninsular Rivers? Discuss.

Answer : 

Himalayan Rivers and Peninsular Rivers differ in their origin, nature, and geographical characteristics.

Himalayan Rivers, such as the Ganga, Yamuna, and Brahmaputra, originate from glaciers and snow-covered mountains of the Himalayas. They are perennial rivers, meaning they flow throughout the year because they receive water from both glaciers and rainfall. These rivers carry large quantities of water and sediments, creating extensive floodplains and fertile agricultural regions.

In contrast, Peninsular Rivers such as the Godavari, Krishna, Kaveri, and Narmada originate from plateaus, hills, and the Western Ghats. They are primarily rain-fed rivers and are therefore seasonal in nature, with water flow depending largely on monsoon rainfall.

Himalayan Rivers are generally longer, have larger drainage basins, and frequently change their courses due to heavy sediment deposition. Peninsular Rivers flow through hard rock regions, have relatively stable courses, and carry less sediment.

While Himalayan Rivers are more suitable for irrigation and inland navigation, Peninsular Rivers are important sources of hydroelectric power due to their steeper gradients and waterfalls.

Differences Between Himalayan and Peninsular Rivers

Basis	Himalayan Rivers	Peninsular Rivers
Origin	Glaciers and snowfields of Himalayas	Plateaus and hills of Peninsular India
Nature	Perennial	Mostly seasonal
Water Source	Snowmelt and rainfall	Mainly rainfall
Length	Longer rivers	Comparatively shorter
Sediment Load	High	Low
Course	Meandering and changing	Stable and fixed
Floods	Frequent	Less frequent
Navigation	More suitable	Limited suitability

Conclusion

Both Himalayan and Peninsular rivers are vital for India's economy, agriculture, and water security. While Himalayan rivers provide perennial water supply and fertile plains, Peninsular rivers contribute significantly to irrigation and hydroelectric power generation.
