Satellite aquifer checks enabled
Researchers have developed a way to use satellite data to find how long it takes for an aquifer to refill.
The method can determine the recharge area for a spring using satellite-based precipitation data, which is compared to changes in flow of the spring.
That is, when there are surges in the spring flow, experts will be able to look at satellite data to see where it has recently rained.
The technique was developed for karst aquifers, which are filled by precipitation and groundwater and provide a large proportion of the world's drinking water.
It is expected to have important applications in protecting spring water resources worldwide.
