Every day, the De Las Vueltas River receives water from glaciers, streams, and lagoons throughout the northern basin. But where does every drop that forms it actually come from? Within that current, waters of different origins coexist: snow accumulated in the highlands, glacial ice formed over centuries, rain from last week, and water that spent time in a lagoon under the Patagonian sun. To the naked eye, it is impossible to tell them apart. However, water carries a mark of its origin—and for...

Modelling a river without gauging stations: how citizen science and a bit of creativity are reshaping hydrology One of the main challenges of contemporary hydrology is that most rivers worldwide lack discharge gauging stations that continuously record water flow. Many hydrologists acknowledge that continuous discharge data are extremely limited outside well-developed monitoring networks. This limitation has historically motivated global initiatives such as the Decade on Prediction in...

In this edition of the blog, we interview Daniela Schmidt , a PhD candidate at the Faculty of Exact and Natural Sciences of the University of Buenos Aires (UBA), who studies Glacial Lake Outburst Flood (GLOF) processes at Laguna Torre . Daniela shares the progress of her doctoral research, what we currently know about the mechanisms that trigger these sudden drainage events, and how they are modeled in a territory that is rapidly changing due to glacier retreat. We also discuss the key role...
