The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured the top image of floods near the northern shore of the Dominican Republic on November 1. The image was made with a combination of infrared and visible light so that water is black, plant-covered land is bright green, and clouds are pale blue and white. Run-off from the floods filled the Yuna River with sediment, coloring the water blue. The sediment also colors the Atlantic Ocean near the mouth of the river. As the lower image shows, the Yuna River is not visible in MODIS imagery under normal conditions, but in the November 1 image, the river has swollen enough to be clearly seen beneath a thin veil of clouds. The flooded delta covers several kilometers.
India’s Brahmaputra River was already flooded in early August, but those floods turned out to be small compared to the floods that hit the river in early September. The river flooded for the third time in 2007 when monsoon rain pounded northeastern India, Bhutan, and Bangladesh in September.
