Consider the following statements regarding Himalayan rivers and Penin...
The correct answer is option 'C' - 1 only.
Explanation:
- Peninsular rivers are seasonal whereas Himalayan rivers are perennial in nature:
- Peninsular rivers are rivers that flow in the Peninsular region of India. Examples include the Godavari, Krishna, Kaveri, etc.
- These rivers are mostly rainfed and receive water mainly from the monsoon rainfall.
- As a result, they have a seasonal flow, with high discharge during the monsoon season and low to no flow during the dry season.
- On the other hand, Himalayan rivers have their sources in the Himalayan mountains and are fed by snowmelt and rainfall.
- These rivers have a continuous flow throughout the year and do not dry up completely even during the dry season.
- Therefore, the statement that peninsular rivers are seasonal whereas Himalayan rivers are perennial is correct.
- The Peninsular rivers shift their course more frequently than the Himalayan rivers:
- This statement is incorrect.
- Himalayan rivers are young and have a steep gradient, which makes them more prone to changing their course due to geological processes such as tectonic activity, landslides, and erosion.
- On the other hand, peninsular rivers flow through relatively stable geological regions and do not experience significant changes in their course over time.
- Therefore, the statement that peninsular rivers shift their course more frequently than Himalayan rivers is incorrect.
- Unlike the Peninsular rivers, Himalayan rivers are old with a graded profile:
- This statement is incorrect.
- Himalayan rivers are relatively young in geological terms and have a steep gradient.
- They flow through narrow valleys and often have rapids and waterfalls due to the steep descent.
- On the other hand, peninsular rivers are older and have a relatively gentle gradient.
- They have a wider floodplain and meander through the landscape.
- Therefore, the statement that unlike peninsular rivers, Himalayan rivers are old with a graded profile is incorrect.
In conclusion, only statement 1 is correct, and the correct answer is option 'C' - 1 only.

Consider the following statements regarding Himalayan rivers and Penin...
On the basis of the mode of origin, nature and characteristics, the Indian drainage may also be classified into the Himalayan drainage and the Peninsular drainage.
Comparison between the Himalayan and the Peninsular River:
Comparison between the Himalayan and the Peninsular River:
- Himalayan rivers originate from the lofty Himalayan ranges while Peninsular Rivers originate in the Peninsular Plateau.
- The Himalayan rivers are perennial in nature, i.e., water flows throughout the year in these rivers. These rivers receive water both from the monsoons and snow-melt. While the Peninsular rivers receive water only from rainfall and water flows in these rivers in the rainy season only. Therefore, these rivers are seasonal or non-perennial. Hence, statement 1 is correct.
- Himalayan rivers have large basins and catchment areas while Peninsular rivers have small basins and catchment areas.
- Himalayan rivers flow through deep V-shaped valleys called gorges. These gorges have been carved out by down cutting carried on side by side with the uplift of the Himalayas. While the Peninsular rivers flow in comparatively shallow valleys. These are more or less completely graded valleys. The rivers have little erosional activity to perform.
- Himalayan rivers flow across the young fold mountains and are still in a youthful stage, while Peninsular rivers have been flowing in one of the oldest plateaus of the world and are old rivers with graded profile, and have almost reached their base levels. Hence, statement 3 is not correct.
- When Himalayan rivers enter the plains, there is a sudden reduction in the speed of flow of water which forms meanders and shifts their beds. While, in case of Peninsular rivers, the hard rock surface and non-alluvial character of the plateau permits little scope for the formation of meanders. As such, the rivers of the Peninsular Plateau follow in fixed course with well-adjusted valleys. Hence, statement 2 is not correct.
