Monsoon climate
most areas have 1800-2000mm per year, concentrated from June to September. This coincides with Himalayan snowmelt

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.

Soil erosion due to deforestation
Topsoil is deposited in the river, limiting potential discharge. The bed of the Brahmaputra is rising 5cm per annum

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.

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

ensures rural population knows how to react. Due to traditional societies disapproving of women/men mixing, children can pass on information to their parents
