Flooding in Eastern India
| Title |
Flooding in Eastern India |
| Description |
Abutting the southern front of the snow-clad Himalaya Mountains, the broad, flat Ganges Plain is laced with rivers that transport glacial melt to the Bay of Bengal or the Arabian Sea. Not surprisingly, these rivers lead something of a Dr. Jekyll–Mr. Hyde existence: during the dry winter, the rivers are small and sedate, their headwaters largely locked in ice. In the summer, temperatures in the mountains climb, melting mountain-top snow and fueling the Asian monsoon, and the rivers swell into roaring giants. Not every year is the same however—the monsoon may be wetter in a particular year or winter snows might be greater, leading to more snowmelt—and 2007 numbered among the more extreme flood years. Heavy rain throughout July pushed the Ganges and its many tributaries over their banks, submerging large tracts of land in northeastern India. As of August 3, nearly 20 million people had been displaced in India, Bangladesh, and Nepal, and 125 had died in India, reported BBC News. [ http://news.bbc.co.uk/2/hi/south_asia/6927389.stm ] Among the most severely hit states was India's northeastern Bihar state. The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) flying on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured the top image of flooding on the Ganges and its tributaries on August 3, 2007. The lower image, captured by Aqua MODIS on June 4, 2007, shows the plain before the summer monsoon and snowmelt swelled the rivers. In these images (made with a combination of infrared and visible light), water is black or dark blue. Water takes on a brighter shade of blue when tinged with sediment. Clouds, pale blue and white, are scattered over the flooded region, which is bright green with vegetation. Sparsely vegetated areas or bare earth in the lower image are rose-tinted tan. On August 3, the Ganges, Gandak, and Kosi Rivers were so swollen that it was hard to see exactly where the rivers normally flow. The tributaries that feed the Kosi River, not even visible on June 4, have combined in a vast web of water-covered land. The light blue area under the clouds in the lower left corner of the image is probably water-soaked earth, not standing water. Though destructive, seasonal flooding in the Ganges River system blankets the plain with fertile alluvial soil, making it productive farmland. Because the plain is so fertile, it is one of the most densely populated regions on Earth.Daily images [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?FAS_India3/2007215 ] of northeastern India are available from the MODIS Rapid Response System in both false color, as shown here, and photo-like true color.

Flooding in India and Bangladesh |
| Description |
India's Brahmaputra River was already flooded in early August (bottom image), but those floods turned out to be small compared to the floods that hit the river in early September (top). The river flooded for the third time in 2007 when monsoon rain pounded northeastern India, Bhutan, and Bangladesh in September, reported the BBC [ http://news.bbc.co.uk/2/hi/south_asia/6988590.stm ] on September 11. As these images illustrate, the September floods were the worst of the year, forcing the Indian government to evacuate some 800,000 people from the banks of the river. An additional 500,000 people were evacuated downstream in Bangladesh. The floods damaged crops that had been replanted after the August floods, said the BBC. The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured these images of the swollen river. Both images were made with a combination of infrared and visible light, which makes water appear black or dark blue. Plant-covered land is bright green, and clouds are turquoise and white. In the top image, taken on September 12, the Brahmaputra is more than 25 kilometers wide in places. The braided channels of the river disappeared as water levels rose enough to blend the channels into a single wide, blue ribbon. Tributaries flowing in from the Himalayan kingdom of Bhutan are also swollen. The water is a dusty blue color compared to the dark blue color seen in early August. The lighter shade of blue indicates that the water is thick with sediment, a common sign of recent flooding. MODIS captured the lower image on August 5, 2007, during the year's second round of flooding on the Brahmaputra. The river is wider than it had been during the dry season, [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?FAS_Bangladesh/2007123/FAS_Bangladesh.2007123.aqua.721 ] but it is much smaller than it would become a month later.

Floods in Bangladesh |
| Description |
Northeastern Bangladesh disappeared under monsoon floods as rains drenched the region in June 2006. By June 21, when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured the top image, the floods stretched across hundreds of kilometers of what had been dry land a month earlier. According to Reuters, [ http://www.alertnet.org/thenews/newsdesk/DHA197717.htm ] the floods claimed nine lives, made 10,000 homeless, and marooned more than a million by June 18. The monsoon rains typically last from June to September. These satellite images of the floods combine MODIS' observations of shortwave and near-infrared wavelengths of light with visible light to allow water to stand out against the land. Water is black and dark blue. Plant-covered land is green, and clouds are pale blue and white. The MODIS Rapid Response Team provides daily images [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?FAS_Bangladesh/2006172 ] of Bangladesh in both infrared and photo-like natural color.

Floods in Bangladesh |
| Description |
By June 20, 2007, the summer's first floods had engulfed northeastern Bangladesh. Monsoon rains routinely flood the low-lying country in the summer, though some years are worse than others. This image, captured by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite, is centered on the northeast administrative region, Sylhet. Water, dark blue and black in the false-color image, covers most of the region. The floods destroyed several villages, trapped thousands of families, and forced thousands of evacuations, reported the Gulf Times on June 20. Officials were expecting the floods to worsen as monsoon rains continue to fall. The lower image, captured by Terra MODIS, shows Bangladesh on May 1, before the monsoon started. Even during the dry season, the region is spotted with dark pools of water, an indication that the land may be marshy year-round. Both images were made with a combination of infrared and visible light to increase the contrast between water and earth. Plant-covered land is bright green, bare earth is tan, and clouds are light blue and white. The Bangladeshi capital, Dhaka, is a concentrated area of gray in the lower left corner of the image.Daily images [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?FAS_Bangladesh ] of Bangladesh are available from the MODIS Rapid Response System in both false color, as shown here, and photo-like true color.

Floods in Bangladesh
| Title |
Floods in Bangladesh |
| Description |
A large portion of Bangladesh was awash with floods when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured the top image on August 3, 2007. The low-lying nation is an alluvial delta, and therefore, is extremely prone to flooding. In July 2007, heavy monsoon rains filled the Brahmaputra, Padma, and Meghna Rivers, leading to the floods shown here. The Jamuna, a branch of the Brahmaputra River, arcs through the center of the scene, its braided waterways woven into a single thread where the river is overflowing. A branch of the Jamuna flows east into the Meghna River. The wetlands that surround these rivers are full of water, and the rivers themselves are swollen. The Padma River, formed by the convergence of the Ganges and Jamuna Rivers, is also flooded. The severity of the floods can be seen in the contrast between the top image and the lower image, which was taken on May 1, 2007, before the monsoon rains began. In the dry season, the course of each river is clearly defined, not blurred by excess water. The images were made with infrared and visible light to increase the contrast between water and earth. In this type of image, water is black or blue, where colored with sediment. Plant-covered land is bright green, and bare earth or lightly vegetated areas are tan. Light blue and white clouds dot the scene. In the lower image, red dots mark the location of fires. The floods shown here stranded hundreds of thousands of people in Bangladesh, one of the world's most densely populated nations, reported BBC News. [ http://news.bbc.co.uk/2/hi/south_asia/6927389.stm ] As of August 3, nearly 20 million people had been displaced by monsoon flooding in Bangladesh, India, and Nepal, added BBC. Some of the floods in northeastern India [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14429 ] were visible when Aqua MODIS flew over on August 3. The intense rains of the summer monsoon typically fall between June and October, so additional flooding is likely.Daily images [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?FAS_Bangladesh/2007215 ] of Bangladesh are available from the MODIS Rapid Response System in both false color, as shown here, and photo-like true color.
