Wander where and when the next major river flood would had, just look up to the satellites. Conventional estimates a river volumes come from rain fall of course and from measurement of the water the same from the soil and grand water reserves.

But the nest grate satellites for gravity recovery and climate experiment can pick up changes and the gravity field in a given river basin. The more water in the basin the higher of the gravity signal.

Scientists use great the results to 2003 and 2005, to see if they could predict the 500 year flooding event in the mosiry river basin in 2011. Proceeding¹ the flood were too significant storm storms, records snow, saturated² soils and particularly high grand water. With the greasy³ data the researchers found that they could predict the mosiry river floods month before the current prediction models. The say the technique could be used to forecast floods up to 11 month before such events take place in areas where snow mountains and grand water was significant contribution.

The researchers published in the Journal Nature Geoscience.

Snow mountains in a major rain storms are predicted to increase was the climate change which is put premier⁴ on better flood prediction.

Thanks for the minute. For Scientific Americans 60-Second Science. I am Synthia Graber.
