Drainage System of India (Complete) – India Geography – Free PDF Download



  • The flow of water through well-defined channels is known as drainage and the network of such channels is called a “drainage system”.
  • The drainage system of an area is the outcome of the geological time period, nature and structure of rocks, slope, topography, amount of water flowing and the periodicity of flow.
  • The area drained by a single river system (river and its tributaries) is called its drainage basin.
  • An elevated area (mountain or an upland) that separates two drainage basins is called a “water divide”.
  • The world’s largest drainage basin is of the Amazon river and in India, the river Ganga has the largest river basin.
  • The Himalayan RiversPerennial rivers: Indus, the Ganga, the Brahmaputra and their tributaries.

  • The Peninsular Rivers: Non-Perennial rivers: Mahanadi, the Godavari, the Krishna, the Cauvery, the Narmada and the Tapi and their tributaries.
