Ganges Delta. Coloured satellite image of the delta of the Ganges River,Bangladesh,which runs into the Bay of Bengal (bottom). North at top. Swamp forest (known as Sunderbans) is light green,vegetation is dark green,urban areas are grey and sediment is purple. A delta is formed from the deposition of sediment at the mouth of a river. Deltas may be transitory and new channels are constantly forming while others become blocked. Over 120 million people live on the Ganges Delta,under the constant threat of floods.
