A new study reveals that the Sierra Nevadas are a significant source of groundwater for California's Central Valley aquifer, with some areas relying almost entirely on it. The research found that the groundwater is mixed in age, with some water being as young as 4 years old and others dating back over 40,000 years.
Research reveals that groundwater levels are dropping in 71% of aquifers globally, with accelerating declines in drier climates. However, the study also highlights successful interventions, such as water recharge and demand reduction strategies, which can help stabilize or recover aquifer systems.
Researchers have developed a new method to measure the duration and severity of hydrological droughts in streams and rivers, which can persist for up to 3.5 years after drought conditions end. The study found that baseflow droughts are strongly tied to groundwater levels and can impact water management and ecosystem services.
Researchers applied a new integrated model linking surface water to groundwater to estimate water resources at high spatial resolution. The study found that irrigation increases atmospheric water loss but reduces groundwater support, especially during dry seasons.
