Regional groundwater models often use smoothed topography to reduce computational burden—but what does this shortcut actually cost? Here, the team examines how “water table smoothing” propagates into simulated flow patterns and groundwater–river exchanges. Using a 95-km 2D cross-section based on the hydrogeology of Québec’s St. Lawrence south shore (Canada), they... read the story...

The Bolje Sestre karst spring has been supplying potable water to the entire Montenegrin Coast since 2010, representing one of the largest water supply projects completed in the entire Mediterranean Basin over the last 50 years. The considerable depletion of spring discharge that occurred in the meantime required multidisciplinary research... read the story...

The water supply of the City of Cape Town, South Africa, is highly dependent on surface water and therefore highly sensitive to drought. Since the 2015-2018 drought period, there has been a significant drive to identify and operationalize alternative water sources for the City of Cape Town (including groundwater). A... read the story...

Bonanza Spring in the Clipper Mountains (California U.S.A.) is the largest spring in the Eastern Mojave Desert. There has been concern that the spring and its dependent ecosystem might be hydrogeologically linked with a wellfield 22 km downgradient. This year-long study compared key spring and wellfield water quality parameters, with... read the story...

A nano technology-based synthetic DNA-labelled colloidal tracer was tested for the first time in a fractured calcarenite in the Northern Apennines (Italy). The analytical procedure is based upon the qPCR protocol. The results of the application, carried out by an interdisciplinary research group of hydrogeologists and molecular biologists from the... read the story...

I am excited to write about my experience during the 52nd International Association of Hydrogeologists Groundwater Congress in Melbourne, Australia, as an Early Career researcher in the domain of groundwater, and a Steering Committee member of the Early Career Hydrogeologists’ Network (ECHN), IAH. This was my third IAH Congress, and... read the story...

In order to celebrate International Women’s Day this year, we asked some of our council members to reflect on women who inspire them. Here is what they said: Dr Teodóra Szőcs – President: “Mary W. Jackson is a fantastic example to me, as a woman who successfully overcame the barriers... read the story...

This book explores large and thermal springs in the United States: their origin, characteristics, historical and current uses, and significance. Some of these springs are among the largest and most spectacular in the world and many were and are sacred to Native Americans. Contemporary and historic photographs reveal their beauty... read the story...
