Why does the Narmada not form deltas

Difference between Himalayan and Peninsula rivers

Rivers are described as the large natural body of water that flows to the sea or to another river. It is one of the main sources of water supply for living things. In India, the rivers are broadly classified as Himalayan Rivers and Peninsula Rivers. Himalayan rivers are the watercourses that originate from the Himalayan waters and are perennial in nature. On the contrary, they Peninsula rivers are those that are from the Western Ghats and are not perennial.

The catchment area of ​​the Himalayan rivers is very fertile, while the catchment area of ​​the peninsula is not very fertile. The article excerpt can help you understand the difference between Himalayan and Peninsula rivers.

Definition of Himalayan rivers

Himalayan rivers are referred to as rivers that originate from Himalayan mountain ranges that draw both water and rain melt from glaciers. The Indus, Ganga and Brahmaputra are the three major Himalayan rivers. These help with irrigation and cultivation of arid areas and farms all year round.

Himalayan rivers are characterized by long routes from their source to the sea. They carry a large amount of sand and silt in the upper passages due to their exhaustive erosion activity. In addition, they form meander and ox arches in the middle and lower reaches.

Himalayan rivers form large deltas. The Sundarban Delta is one of the largest delta formed by the Ganga and Brahmaputra.

Definition of peninsula rivers

Peninsula rivers are the seasonal rivers as their flow mainly depends on rainfall. In these rivers, the water flow decreases in the dry season, even if it is long. They are characterized by short and flat courses.

Most of the peninsula rivers originate in the Western Ghats, flow eastwards and flow into the Bay of Bengal. It includes rivers like the Mahanadi, Godavari, Krishna and Cauveri etc. that form deltas. However, the Narmada and the Tapi are the two rivers whose starting point is the central highlands, and they flow towards the west and form estuaries. Estuaries are nothing more than small deltas.

Main differences between Himalayan and Peninsula rivers

The points below illustrate the difference between the rivers of the Himalayas and the Peninsula:

  1. Himalayan rivers are the bodies of water that emanate from the north of the Himalayan mountain ranges. On the other side of the peninsula are the rivers of the western ghats or the central highlands.
  2. The Himalayan rivers are perennial, meaning they have water all year round. In contrast, peninsula rivers are seasonal in the sense that they only have water during a certain period of time.
  3. Himalayan rivers form large deltas. On the other hand, some peninsula rivers such as the Mahanadi, Godavari, Krishna, and Cauveri form deltas, while the Narmada and Tapi form estuaries.
  4. While Himalayan rivers meander, peninsulas do not meander.
  5. The foundation stones of the Himalayan rivers are soft, sedimentary and easily eroded. Conversely, the rocks of the peninsula rivers are hard, resilient and not easily eroded.
  6. Himalayan rivers get water from snow and rain, while peninsula rivers are only fed by rain.
  7. The catchment area of ​​the Himalayan rivers is comparatively larger than that of the peninsula.
  8. The waters of the Himalayan River help irrigate the northern plains. In contrast, peninsula rivers irrigate the Deccan Plateau.
  9. Himalayan rivers form a V-shaped valley while peninsula watercourses form a U-shaped valley

Conclusion

The length of the canal and valley of the Himalayan river system is greater compared to the Peninsular River system. In the case of Himalayan rivers, although water is added from the underground springs, in the case of peninsula rivers, due to the hard lithology, no underground water is added to the river.
