  • Snowmelt in the Himalayas increased the quantity of water in rivers
  • Tropical cyclones added more water to rivers
  • Heavy monsoon rains caused there to be more water in rivers
  • 70% of the land is less than 1m above sea level
  • 10% of the land is covered in water normally (lakes and swamps)
  • Entire country acts as a flood plain for the Ganges and Brahmaputra rivers

Causes (physical and human) 2


  • Deforestation in Nepal and Tibet meant that less water was absorbed by vegetation
  • Dams built in India meant that more water reached Bangladesh
  • Urbanisation meant that there were more impermeable surfaces so less infiltration of water
  • Global warming caused sea levels to rise making Bangladesh more prone to flooding
