This image of the Ganges River Delta in Bangladesh was acquired by the Landsat- 7 satellite on February 28, 2000. It's a false-color composite image made using green, blue and near infrared wavelengths, provided by the USGS, EROS Data Center. The Ganges River forms an impressive and extensive area of distributaries where it empties into the Bay of Bengal after moving across India. This delta is referred to as the Sunderbans and is home to approximately 120 million people. It's routinely flooded during cyclones and monsoonal rains. Because its inhabitant are so poor and the delta is so densely populated, even when flood and storm warnings are issued, each year thousands of people lose their lives as a result of floods. Note the sediment (milky blue color) flowing from the delta into the Bay of Bengal.
