Surface deformation in the Central Valley has long been linked to changes in groundwater storage, but the timing and movement of water flow beneath the surface has been poorly understood due to a lack of reliable data. Scientists are now using advanced satellite data to map the “pulse” of groundwater... read more...

The majority of people in rural Africa and a large proportion in its urban areas rely on groundwater for drinking, hygiene, and development. The rate at which groundwater is replenished is often unknown making regional water security difficult to assess. A recent study showing the continent’s groundwater recharge rates may... read more...

World Water Day 2021 focuses on the theme, ‘Valuing Water’, which is the subject of this year’s United Nations World Water Development Report. Valuing water extends beyond issues of price: it also takes into account the environmental, social, and cultural value people place on water. Groundwater has always been of... read more...

A collection of seven articles in Hydrogeology Journal (March 2021) explores groundwater recharge and discharge processes in arid and semi-arid areas of China. The groundwater resources have undergone observable changes in water quality and quantity as a result of human activities and climate change. These articles provide insight into surface... read more...

Karst aquifers have a worldwide distribution. Their unique characteristics, such as triple porosity (matrix, fractures and conduits) and extremely fast groundwater flow, set them apart from aquifers of other rock types. Our Hydrogeology Journal (February 2021) provides a state-of-the-art overview of advances in karst hydrogeology since the foundation of the... read more...

New research has revealed how an invasion of the alien evergreen tree, Prosopis juliflora seriously diminishes water resources in the Afar Region of Ethiopia. These invasive trees in drier parts of the country have substantially reduced groundwater in aquifers, on which local farmers and towns are totally reliant. Find out... read more...
