Study: Droughts May Affect Groundwater More Than Expected

摘要

On the Earth's surface, the end of a drought is usually obvious. Rainfall arrives, streams and rivers increase in volume or begin to flow again, vegetation perks up, and parched soils regain their moisture. But what about below the earth's surface? In particular, how does groundwater respond to the end of drought? Given the critical role that groundwater plays in many regions as a source of water for drinking and irrigation, understanding the effects of droughts on aquifers could help shape management decisions regarding these key resources.
