Study Notes

Drainage Systems in India

  • Drainage describes the river system of an area
  • Small streams converge into larger rivers, draining into a larger body of water (lake, sea, ocean)
  • Drainage basin: area drained by a single river system
  • Water divide: elevated area separating two drainage basins (mountains, uplands)

Major Groups of Indian Rivers

  • Himalayan rivers: perennial (water year-round), originate in the Himalayas, receive water from rain and melting snow, long courses

  • Peninsular rivers: seasonal (flow dependent on rainfall), shorter courses, originate in the central highlands, flow towards the west or Bay of Bengal

Himalayan Rivers

  • Indus River System:

    • Originates in Tibet, enters India in Ladakh, flows through Kashmir, Baltistan, Gilgit and Attock.
    • Major tributaries: Zaskar, Nubra, Shyok, Hunza, Satluj, Ravi, Chenab, Jhelum
    • Flows through Pakistan eventually reaching Arabian Sea.
  • Ganga River System:

    • Originates in the Gangotri Glacier, joined by Alaknanda;
    • Large tributaries: Yamuna, Ghaghara, Gandak, Kosi, Chambal, Betwa, Son.
    • Flows east into the Bay of Bengal (forming the Sunderban Delta).
  • Brahmaputra River System:

    • Originates in Tibet (Tsang Po), enters India as Dihang, joins the Ganga and flows to the Bay of Bengal.
    • Major tributaries: Dihang, Lohit, others
    • Similar Characteristics as other Himalayan rivers

Peninsular Rivers

  • Seasonal flow; originate in Western Ghats; flow towards the Bay of Bengal.
  • Noted Rivers: Narmada, Tapi
  • Often shorter courses and shallower than Himalayan rivers
  • Notably, the Narmada flows west into the Arabian Sea
  • Other Rivers: Godavari, Krishna, Kaveri.

River Basins

  • Regions drained by major rivers; often impacted by seasonal rainfall patterns.

  • Indus Basin: stretches across parts of India and Pakistan, largest in India.

  • Ganga Basin: large and spans across India, important for agriculture.

  • Brahmaputra basin: extensive regions including parts of India and neighboring countries.

River Pollution

  • Domestic, industrial, and agricultural activities can affect water quality in rivers.
  • Important to understand the importance of water for livelihood, agriculture, etc. leading to concerns over pollution.

Lakes

  • Natural lakes; formed by glaciers, tectonic activity, human action
  • Important as tourist attractions, sources of water etc.
  • Specific examples include Wular, Dal, Chilika and Sambhar.
