What to Focus On

  • Indian drainage is divided into Himalayan rivers and Peninsular rivers on the basis of evolution.
  • Himalayan rivers are antecedent drainage because they existed before the mountains were formed.
  • The Indobrahma or Shiwalik river is a hypothesised ancient river system.
  • The Himalayan river system has three major drainage systems.
  • Himalayan rivers are perennial because they receive snowmelt and rainfall.
  • They form deep gorges and often change course.
  • The Indus is one of the longest rivers in the world.
  • The Indus has five main tributaries in the Punjab region.
  • Jhelum, Chenab, Ravi, Beas and Satluj together form the Indus drainage system.

Common Mistakes to Avoid

All Indian rivers behave in the same way and can be grouped without noticing major differences between Himalayan and Peninsular rivers.

The Indus, Ganga, and Brahmaputra are separate types of rivers that do not share a common Himalayan origin.

A gorge is a wide river valley with gentle sides formed by deposition.
