According to NASA the floods in Pakistan is so bad that it changed the appearance of the lower Indus River.
NASA said the following about the satellite images:
A flood surge heading for Pakistan’s coast changed the appearance of the lower Indus River in just four days. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured these images on August 8, 2010 (top), August 10, 2010 (middle), and August 12, 2010 (bottom).
All three images use a combination of infrared and visible light to increase the contrast between water and land. Water appears in varying shades of blue. Vegetation is green, and bare ground is pinkish brown. Clouds range in color from pale blue-green to bright turquoise. A thin veil of clouds hangs over much of the region on August 12.
On August 8, even though the lower Indus has risen far above its typical levels, it still appears as a relatively thin braided stream south of Sukkur. On August 10, the river has widened south of the city, and on August 12, the Indus has risen even more. Compared to the previous two images, the water appears fairly light in color on August 12. This may result from the angle of sunlight or from cloud cover, but might also result from an increased sediment load in the water.
