Sanjay lives with his wife and 4 children
Sanjay has a field just outside the village where he grows vegetables
Rainfall is concentrated into a few months
Sanjay’s mother and father drowned 11 years ago
Sanjay lives in a small rural village in the Ganges Delta
The area where Sanjay lives is low-lying
The river is held back by small levees above the level of the surrounding land
A levee is an earth bank which is designed to hold back a river
Bangladeshi Authorities and international aid groups are worried about the people who live around the River Ganges
The area is poor and cannot afford a barrage.
Deforestation has occurred in the Himalayas
The area around Sanjay’s village is intensively farmed.
Sanjay’s village maybe small, but there are many people living in farms around the village
There is no TV or radio in Sanjay’s village
High winds and tides combine to form storm surges
The Bay of Bengal is a funnel shape and gets shallower towards the coast.
If the ground is saturated then surface run-off will be very high

The river can spread quickly across flat land
The Ganges Delta is part of the floodplain of the River Ganges
Tropical rains called monsoons bring large amounts of rain
The banks of the River Ganges need to be reinforced
The land around the River Ganges is very flat

People are being encouraged to build houses on raised mounds
