GEOGRAPHY THROUGH MAPS

Ganga–Brahmaputra–Meghna system

This connected river system links Himalayan and Tibetan headwaters with the plains and delta of northern South Asia. Its combined lower drainage reaches the Bay of Bengal through Bangladesh.

Fast Facts

  • The Brahmaputra is called Yarlung Tsangpo in Tibet and Jamuna in its main Bangladesh reach.
  • The Ganga and Brahmaputra combine before their lower flow joins the Meghna system; distributary geometry makes bank labels channel-specific in the delta.
  • The basin spans several countries, including mountain catchments in Nepal and Bhutan as well as India, China and Bangladesh.
