Major floods
1987, 1988, 1998, 2004 & 2007
6 of 24
Physical: floodplain
80% of the country is a floodplain, 70% is less than 1m above sea level
7 of 24
Monsoon climate
most areas have 1800-2000mm per year, concentrated from June to September. This coincides with Himalayan snowmelt
8 of 24
Human: deforestation
RPG has led to deforestation for timber, fuel and grazing land. In Nepal, 50% of the forest cover existing in 1950 has gone.
9 of 24
Soil erosion due to deforestation
Topsoil is deposited in the river, limiting potential discharge. The bed of the Brahmaputra is rising 5cm per annum

Dams
7 large dams developed to provide up to 15 floodwater storage systems
18 of 24
Embankments
strengthened along main channels to 7m tall. Over 7500km already in place, costing $6 billion, but incomplete due to corruption and lack of funding
19 of 24
Controlled flooding
land is compartmentalised, with water flow controlledby channels, water pumps and gates. In the dry season, water is moved for irrigation. In the wet season it is drained.

Forecast
Flood Forecasting and Warning Centre in Dhaka - satellite imaging used to forecast, giving more lead time, sending warnings to the whole country
21 of 24
Disaster Response Management
provides damage assessment to help streamline government responses and to help donors channel funds
22 of 24
Education
ensures rural population knows how to react. Due to traditional societies disapproving of women/men mixing, children can pass on information to their parents
