The combined delta of the Ganges
and Brahmaputra Rivers is the largest in the world. This true-color
image from the Moderate-resolution Imaging Spectroradiometer (MODIS)
shows both the delta and sediment flowing into the Bay of Bengal.
Fed by monsoon rains and Himalayan snowmelt, the rivers often flood.
These floods often cause catastrophic damage, but also enrich the soil.
Launched in December 1999, MODIS flies aboard NASA's Terra spacecraft.

This elevation image shows that the Irrawaddy Delta in Burma (Myanmar) is clearly flat, much of it below five meters in elevation. This low elevation makes the delta particularly prone to flooding from storm surges.
