East Flowing Rivers in India

 

East Flowing Rivers in India

• Rivers have been of fundamental importance throughout human history. Water from rivers is a basic natural resource, essential for various human activities.
• Therefore, riverbanks have attracted settlers from ancient times. Using rivers for irrigation, navigation, and hydropower generation is of special significance — particularly to a country like India, where agriculture is the major source of livelihood of the majority of its population.
• The major east-flowing rivers are the Godavari, Krishna, Cauvery, Mahanadi, Pennar, Subarnarekha, Brahamani, Ponnaiyar, Vaigai River, etc.
• East flowing rivers:
  • flow into the Bay of Bengal
  • have many tributaries
  • forms Deltas
  • carry larger sediments than West flowing rivers.
