With shifting rainfall patterns and amounts of water in the ground, the risk of flooding in the US is changing across the nation. Researcher says the north half of the country is at a greater risk of flooding, while the threat has declined in the West, South and Southwest regions.
With shifting rainfall patterns and ground water amounts, the risk of flooding in the US is changing across the nation.
Researcher are now warning the north half of the country is at a greater risk of flooding, while the threat has declined in the West, South and Southwest regions.
After analyzing data from streams and NASA satellites, the team discovered that the amount of ground water in the northern area of the US has increased.
The University of Iowa engineers Gabriele Villarini and Louise Slater made the discovery by comparing data from 2,042 streams with satellite information gathered over more than a dozen of years by NASA's Gravity Recovery and Climate Experiment (GRACE) mission showing 'basin wetness,' or the amount of water stored in the ground.
