A large portion of Bangladesh was awash with floods when the MODIS on NASA's Aqua satellite captured this image on August 3, 2007. 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 another image (BH5907), taken on May 1, 2007, before the monsoon rains began. Images were made with infrared and visible light to increase the contrast between water and earth. 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.
