Bridging the Gap Between Global Tech and Local Expertise: Why We Open-Sourced Google’s Hydrology Framework

Bridging the Gap Between Global Tech and Local Expertise: Why We Open-Sourced Google’s Hydrology Framework

Dear EGU Hydrology community, Over the past few years, machine learning (ML) and artificial intelligence have fundamentally changed what is possible in large-scale hydrological modeling. At Google, our team has worked to develop machine learning river forecast models that operate globally, extending reliable forecasting to ungauged basins and covering almost two billion people through the …[Read More]

eDNA4Hydrology

What flows around comes around For centuries, hydrologists have studied the flow of water through landscapes near and far. We measured flow rates, mapped aquifers and followed invisible paths of raindrops through soil and bedrock. Hydrology is a meticulous, beautiful science that has taught us much over the years. From the water cycle, surface water …[Read More]

Drought in Europe

Drought in Europe

Many of us are experiencing it right now: Europe is suffering from a long lasting large scale drought (Fig. 1), with record heat and low-flow levels that probably nobody of us has seen before; and current forecasts do not announce any relieve for the coming weeks. The pictures of record low levels in the river …[Read More]

Has groundwater finally gone mainstream?

Has groundwater finally gone mainstream?

Groundwater has always had an image problem. Throughout my career, I have lost count of how many times we have described groundwater as an “invisible resource” or similar. It is almost a cliché in hydrogeology. We use the phrase because it captures something really fundamental: groundwater is hidden physically, but it has also been hidden …[Read More]

What machine learning can and cannot tell us about floods

Collage based on a picture by Imad Clicks via Pexel

Floods are shaped by complex and nonlinear interactions between weather patterns, rainfall, soil properties, topography, land cover, and how wet a catchment already is. This complexity is one reason machine learning (ML) is increasingly used in hydrology. ML models can learn patterns from large and complex datasets with many variables.  Early in my PhD, while …[Read More]

HydroTalks: Prof. Thom Bogaard on Water and Landslides, Early Warning Systems, and IAHS-HELPING Decade

HydroTalks: Prof. Thom Bogaard on Water and Landslides, Early Warning Systems, and IAHS-HELPING Decade

For episode 11 of HydroTalks, we welcomed Prof. Thom Bogaard of Delft Technical University and visiting professor at Kasetsart University, Bangkok. His research explores the intersection of hydrology, geomorphology, ecology, and natural hazards. We discussed his work on understanding how water triggers landslides, improving regional early warning systems, and developing practical solutions that reduce disaster …[Read More]
