There is more to freshwater resources than meets the eye. While fresh water is visible in the form of rivers, lakes and glaciers, fresh groundwater resources — hidden beneath the Earth — often go ...

Measuring groundwater depths helps the state monitor how fast resources are depleting in different areas.

Groundwater is rapidly declining across the globe, often at accelerating rates. Writing in the journal Nature, UC Santa Barbara researchers present the largest assessment of groundwater levels around ...

A new study modeled shrub encroachment on a sloping landscape and reached a startling conclusion: Shrub encroachment on slopes can increase the amount of water that goes into groundwater storage. The ...

Any industrial activity near water reserves could, in principle, cause contamination. Isotope hydrology offers a unique combination of methods to monitor water quality and trace the source of ...

Sustainable rates of groundwater withdrawal in Oregon's Harney Basin were surpassed 20 years prior to the time declining groundwater levels were generally recognized, a new analysis found. Sustainable ...

From the Andes’ life-giving rivers to advanced filtration systems, hydrology is at the heart of securing clean, reliable water in a changing climate. New modeling techniques, watershed mapping, and ...

Scientists have discovered that the pace of groundwater depletion in California’s Central Valley has accelerated dramatically during the drought as heavy agricultural pumping has drawn down aquifer ...
