Bangladesh,being situated on the Brahmaputra River Delta is a land of many rivers,and as a result is very prone to flooding. Due to being part of such a basin and being less than 5 meters above mean sea level,Bangladesh faces the cumulative effects of floods due to water flashing from nearby hills,the accumulation of the inflow of water from upstream catchments,and locally heavy rainfall enhanced by drainage congestion. Bangladesh faces this problem almost every year. Coastal flooding,combined with the bursting of river banks is common,and severely affects the landscape and society of Bangladesh. 80% of Bangladesh is floodplain,and it has an extensive sea coastline,rendering the nation very much at risk of periodic widespread damage. Whilst more permanent defenses,strengthened with reinforced concrete,are being built,many embankments are composed purely of soil and turf and made by local farmers. Flooding normally occurs during the monsoon season from June to September. The convectional rainfall of the monsoon is added to by relief rainfall caused by the Himalayas. Meltwater from the Himalayas is also a significant input.

By 3 August,the estimated death toll was 41 people,and 48 schoolgirls were marooned in a school in the Darbhanga district. By 8 August,the flooding had impacted an estimated 10 million people in Bihar. Army helicopters delivered food packets to residents,and 180 relief camps were established.

The total number of deaths recorded in the 2007 Bihar floods was more than 1,300,the highest death toll in the state since the 1987 Bihar floods,in which more than 2,500 deaths were reported.

The immediate causes of the floods were heavier than usual monsoon rains and melting glaciers that followed a severe heat wave,both of which are linked to climate change.
From January to October 2022,excessive rainfall and widespread monsoon flooding occurred in the South Asian countries of Afghanistan,Bangladesh,India,Nepal,Pakistan,and Sri Lanka. It has become the region's deadliest floods since 2020,with over 4,700 people dead.
