Bangladesh flooding
Why Bangladesh Floods So Often
Low-lying land:
Most of Bangladesh is flat and close to sea level.
Monsoon rains:
Heavy rainfall from June to September can overwhelm rivers.
River systems:
Major rivers like the Ganges, Brahmaputra, and Meghna carry huge volumes of water from upstream countries (India, Nepal, Bhutan).
Cyclones & storm surges
: Tropical storms from the Bay of Bengal bring strong winds, rain, and sea flooding.
Snowmelt from the Himalayas:
In summer, melted snow adds to river levels.
Deforestation and poor drainage:
Less vegetation and blocked water channels make it worse.
Climate change:
Rising sea levels and more extreme weather increase flood risks.
