Sambhav-2023

Answer 1

Approach

• Write an Introduction about Himalayan and Peninsular River systems.
• Highlight the differences between Himalayan and Peninsular River Systems.
• Write a holistic and effective conclusion.

Introduction

• The Himalayan River system refers to the network of rivers that originate in the Himalayas, the mountain range that runs through parts of India, Pakistan, China, Nepal, Bhutan, and Afghanistan. Some of the major rivers in this system include the Ganges, Indus, Brahmaputra, and Yangtze.
• The Peninsular River system, on the other hand, refers to the rivers that originate in the Deccan Plateau and flow towards the Bay of Bengal and the Arabian Sea. Some of the major rivers in this system include the Godavari, Mahanadi, and Kaveri.

Body

• The Himalayan River system, which originates in the Himalayas, is known for its:
  • Young age: The rivers are relatively young and have not had as much time to erode and shape the landscape.
  • Steep gradients: The rivers have a steep gradient as they flow from the high elevations of the Himalayas to the plains
  • Large volume of water: The rivers have a large volume of water due to the high precipitation and snowmelt in the Himalayas
  • Long courses: The rivers have long courses as they flow through several countries before reaching their mouths
  • High hydroelectric power generation potential: The large volume of water and steep gradients make these rivers suitable for hydroelectric power generation
• The Peninsular River system, which originates in the Deccan Plateau, is known for its:
  • Old age: The rivers are relatively old and have had a lot of time to erode and shape the landscape
  • Gentle gradients: The rivers have a gentle gradient as they flow from the Deccan Plateau to the coast
  • Lower volume of water: The rivers have a lower volume of water compared to Himalayan rivers due to lower precipitation and snowmelt in the region
  • Shorter courses: The rivers have shorter courses as they flow through a smaller area before reaching their mouths
  • Mainly used for irrigation and drinking water: The rivers are mainly used for irrigation and as a source of drinking water for the surrounding population

Conclusion

The Himalayan and Peninsular River systems are two distinct systems of rivers that flow through India, each with its own unique characteristics. The Himalayan River system, which originates in the Himalayas, is known for its young age, steep gradients, large volume of water, long courses, and high hydroelectric power generation potential. The Peninsular River system, which originates in the Deccan Plateau, is known for its old age, gentle gradients, lower volume of water, shorter courses, and mainly being used for irrigation and drinking water. Both river systems are important for the ecology and economy of the region, providing water, power and other resources to the surrounding population.

Answer 2

Approach

• Give a brief Introduction about interlinking of rivers in India.
• Write how it will solve the problems of both drought and flood.
• Write an effective conclusion.

Introduction

• The interlinking of rivers in India, also known as the National River Linking Project, is a proposed infrastructure project that aims to transfer water from surplus river basins to deficit basins by constructing a network of canals, dams and reservoirs.
• The project's proponents argue that it could be an effective solution to address the simultaneous occurrences of drought and floods by redistributing water resources and balancing the availability of water across different regions.

Body

• Interlinking of rivers can help to mitigate the effects of drought by diverting water from surplus basins to deficit basins, thus increasing water availability in regions experiencing water shortages.
• This could help to improve irrigation, drinking water supply and power generation in those regions.
• Additionally, interlinking of rivers can also help to reduce the risk of floods by diverting excess water away from flood-prone areas.
• On the other hand, interlinking of rivers also comes with certain drawbacks and potential risks.
• The project is extremely complex and ambitious, involving the construction of a vast network of canals, dams and reservoirs, which would require a significant amount of time and resources.
• Additionally, the cost of the project is expected to be very high, and it is unclear whether the benefits would justify the costs.
• Moreover, the interlinking of rivers can also have negative environmental and social impacts, such as displacement of communities, loss of biodiversity, and changes in the local hydrological and ecological systems.
• There could also be an adverse effect on the lower riparian areas as the water flow gets impacted.

Conclusion

Interlinking of rivers can be an effective solution to address the simultaneous occurrences of drought and floods, but it is important to carefully consider the potential benefits and drawbacks of the project, and to ensure that any negative impacts are minimized. This can be achieved through a rigorous environmental and social impact assessment, as well as through a transparent and inclusive decision-making process that involves the participation of all stakeholders.
