"Researchers have found a way to predict which rivers are most prone to flooding, by studying satellite data to determine how much water soaked into the ground making it ripe for overflows. 'Just like a bucket can only hold so much water, the same concept applies to river basins. ... This gives the background on what's on the ground before the rain even gets there.'" --J.T. Reager, UC Irvine. Study published in Nature Geoscience.
