A recent study could help scientists predict impending floods months before they occur.
The study states that a pair of NASA satellites, known collectively as GRACE, have detected variations in gravitational pull from saturated river basins that appear to be accurate indicators of flooding.
The report, which was published in Nature Geoscience on July 6th, was conducted by hydrologist J.T. Reager and colleagues from the University of California. The team analyzed data which showed that, as river basins absorb water, GRACE recorded a stronger gravitational pull in the region, suggesting that waterlogged ground is more liable to flooding when assaulted by heavy rain or melting ice.
