Visual representation of Bangladesh Flood

"A large portion of Bangladesh was awash with floods when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua 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."
