Brahmaputra River

  • It originates from the Chemayungdung Glacier in Tibet southeast  Brahmaputra River of Mansarovar lake very close to the sources of the Indus and the Satluj.
  • It is slightly longer than the Indus, and most of its course lies outside India.
  • In Tibet, the river carries a smaller volume of water and less silt as it is a cold and a dry region.
  • It flows eastwards for nearly 1100 Km between the Great Himalayas range to the south and the Kailas Range to the north.
  • On reaching the Namcha Barwa, it takes a ‘U’ turn and enters India in Arunachal Pradesh through a gorge.
  • Here, it is called the Dihang and it is joined by the Dibang, the Lohit and many other tributaries to form the Brahmaputra in Assam. It enters Assam near Sadia.
  • In India, it passes through a region of high rainfall. Hence, it carries a large volume of water and considerable amount of silt.
  • The Brahmaputra has a braided channel in its entire length in Assam and forms many riverine islands. Majuli is the world’s largest riverine island formed by the river.
  • It is marked by huge deposits of silt on its bed causing the river bed to rise. The river also shifts its channel frequently.
  • So every year during the rainy season, the river overflows its banks, causing widespread devastation due to floods in Assam and Bangladesh.
  • It is known as Tsang Po in Tibet and Jamuna in Bangladesh.
  • In Bangladesh, it merges with Ganga to form Padma.
  • Padma joins meghna which flows into the Bay of Bengal.
  • In India, it flows through the states of Arunachal Pradesh, Assam, West Bengal, Meghalaya, Nagaland and Sikkim. The statewise distribution of drainage area is:
