Indus River System is a Himalayan river system and is one of the largest river basins in the world. The Indus Rivier is also known as Sindhu. Therefore, the Sindhu River System is a part of one of the most fertile regions of the Indian sub-continent and the world. Some of the Indian subcontinent’s river systems existed long before civilizations existed. One such river system is the Indus River System.

The main Tributaries of the Indus River form the Indus River System, which includes Indus, Jhelum, Chenab, Ravi, Beas, and Satluj. As the Indus River flows through both India and Pakistan, the Indus water treaty was signed in 1960 for water sharing. Indus River System UPSC topic is an important part of Geography and can be asked in both Prelims and Mains.

What is the Indus River System?

On the basis of the Indus River system, one of the oldest human civilizations was not only developed but also named the Indus Valley Civilization.

  • The name Indus River System has been given because the main river of this system is known as the Indus.
  • The Indus river is also known as the “Sindhu” river in the Sanskrit language.
  • Apart from Sanskrit, the description of Indus in the Greek language is also found as the’ Sinthos’.

The Indus river system is comprised of six perennial rivers, namely: the Indus, Jhelum, Chenab, Ravi, Satluj, and Beas.

The importance of the Indus River System for the Indian sub-continent can be derived from the fact that the name of our country ‘India’ has been extracted from the word ‘Indus’.

Overview of Indus River System

It is important to understand the distribution of the Indus River System in India and Pakistan and also State-wise distribution in India. As per Indus Water Treaty 1960, Indus, Jhelum, and Chenab are under Pakistan, and Rabi, Beas, and Satluj are under India as a water-distribution treaty.

  • Flows through J&K- Indus, Jhelum, Chenab, and Rabi
  • Chenab, Rabi, Beas, and Satluj flow through Himachal Pradesh with the Yamuna
  • Rabi, Beas, Satlu, and Chenab flow through Punjab with Ghaggar

Indus River System also expands to Haryana and Rajasthan through the canal.
