Question

difference between Himalayan drainage system and peninsular drainage system Related:  NCERT Solutions - Drainage System, Class 11, Geography

Answer

There are so many difference b/w himalayan river system and paninsular river system like-

1. himalayan rivers flow over a year whereas paninsular rivers are knownas sesonal rivers because they flows seson by seson
2. himalayan rivers have large drainage system then paninsular rivers.
3. himalayan rivers form deltas but paninsular rivers never form deltas.

Answer

The Himalayan drainage system refers to the network of rivers and their tributaries that originate from the Himalayan mountain range. It is characterized by the presence of perennial rivers that are fed by the melting of glaciers and snow in the Himalayas. The major rivers in this system include the Indus, Ganga, and Brahmaputra.

1. Himalayan Rivers:
- The rivers in the Himalayan drainage system are long, perennial, and have a large volume of water.
- They have a steep gradient due to the high altitude of the Himalayas, resulting in the formation of numerous waterfalls and rapids.
- These rivers are snow-fed, as they receive water from the melting of glaciers and snow during summers.
- The rivers have a high sediment load due to the erosion of the Himalayan mountains.

2. Drainage Patterns:
- The drainage pattern in this system is dendritic, meaning the rivers have a tree-like branching pattern.
- The rivers flow in parallel valleys and join each other at acute angles.
- The tributaries join the main river in a trellis or rectangular pattern.

The peninsular drainage system refers to the network of rivers that flow across the Indian peninsula. It is characterized by the presence of both perennial and non-perennial rivers. The major rivers in this system include the Mahanadi, Godavari, Krishna, and Kaveri.

1. Peninsular Rivers:
- The rivers in the peninsular drainage system are relatively shorter and have a smaller volume of water compared to Himalayan rivers.
- They have a gentler gradient as the peninsular region is relatively flat compared to the Himalayas.
- These rivers are rain-fed, as they receive water mainly from rainfall, and their flow is highly seasonal.
- The rivers have a relatively lower sediment load due to the weathering and erosion of the peninsular rocks.

2. Drainage Patterns:
- The drainage pattern in this system is radial, meaning the rivers originate from a central highland and flow outward in all directions.
- The rivers tend to form deltas near their mouths, as they carry a significant amount of sediment.
- The tributaries join the main river at right angles.

In summary, the Himalayan drainage system is characterized by long, perennial rivers with a high sediment load, while the peninsular drainage system consists of shorter, seasonal rivers with a lower sediment load. The drainage patterns also differ, with the Himalayan system having a dendritic pattern and the peninsular system having a radial pattern.
