Bangladesh flood


	Bangladesh flood
	Causes The Ganges and Brahmaputra rivers bring large volumes of water into the country before entering the sea. Over 150 million people live in Bangladesh, resulting in sinking of many new wells resulting in the lowering of the water table and the subsequent subsidence of land making it even more prone to flooding. Deforestation in Bangladesh and other countries up-stream reduces interception resulting in more water flowing into the rivers with more erosion which is deposited in the river, reducing the channel capacity. In spring, melting snow in the Himalayas enters the rivers at their source, increasing the flood risk. The annual monsoon brings long periods of heavy rain. 70% of Bangladesh is less than 1cm above sea level; 80% is floodplains.	Effects Factories are closed so the whole country loses money (80% of exports are from clothing made here). Food supplies are lost as stocks are destroyed. The floods provide eaterwater and deposit nutritious mud to grow crops, which means farmers don't need to buy expensive fertilisers. Communication and travelling become difficult with roads and railways swept away. This also impacts obon aid ansand rescue missions. Every year people lose their homes as the land is flooded. (30 million made homeless in 1998). People die from drowning, and illness from dirty drinking water. Some also die from snake bites as animals try to escape the floods.;!:£hdhs
