The River System in India, or the Drainage Systems of India, is categorized into 10 types. The major Indian rivers are considered those having a size of a catchment area of 20,000 sq km. There are broadly 3 types of Indian river systems, namely:

  • Himalayan River Systems – Indus, Brahmaputra, and Ganga River System
  • Peninsular River Systems – Godavari, Krishna, Cauveri, and Mahanadi River System
  • West Flowing Peninsular River Systems – Narmada, Tapti, Sabarmati River, Mahi, and Luni River

The rivers of India and their tributaries are of great significance to India as they support millions of lives.
