Flood in Bangladesh and North-east India leave millions homeless.


Four million people have been impacted by flooding in northeastern Bangladesh and Parts of India. The situation could soon worsen, with heavy rain forecast in the next 24 hour. According to Bangladesh water Development Board; By tomorrow evening, Karatoya River is expected to rise by 10-20 cm compared to this evening.

More than 100 people had died due to flooding combined the numbers from India and Bangladesh official figures.

The flood has led to total distriction of communication services in both the nations. Lack of telecommunication services has made it difficult to fully assess the extent of the damage, particularly in the hard-hit parts.

Bangladesh is more effected than India compatibility.

90% of the district of Sunamganj is underwater and is almost entirely cut off from the rest of the country.

The Bangladesh Red Crescent Society plans to help with resettlement efforts and will "provide cash assistance to the flood-affected families," the organization wrote on Twitter late Saturday.

India's Prime Minister Narendra Modi said in a Tweet that he is praying "for the safety and well-being of the people of Assam affected by flooding."Modi said he had spoken to the chief minister of Assam, Hemant Biswa Sharma, and that he had taken "stock of the situation."

Bangladesh is prone to serious and chronic flooding. Even in an average year 18% of the landmass is inundated and previous floods have affected 75% of the country (as in 1988). 75% of the country is below 10m above sea level and 80% is classified as floodplain as Bangladesh is principally the delta region of South Asia’s great rivers.


1. Tectonic uplift of the Himalayas means that erosion rates of sediment increase as the rivers have more potential for erosion. This mass of sediment is dumped in Bangladesh choking the river channels making them more inefficient and reducing hydraulic radius. Sediment is dumped and flooding can occur.

2. Monsoon rainfall some parts of the Ganges basin receive 500mm of rainfall in a day during the monsoon.

3. Three massive rivers converge in Bangladesh – the Ganges, Brahmaputra and Meghna – massively swells discharges.

4. Deforestation of the Himalaya – reducing interception rates which means shorter lag time and higher peak discharges.
