Key Highlights
- Vienna University of Technology professor Günter Blöschl received the 2025 Stockholm Water Prize for pioneering work on flood risk under a changing climate.
- His creation of a global flood‑risk database linked rising flood frequency directly to climate change.
- Blöschl’s modelling advances have improved worldwide flood‑forecasting systems, aiding disaster preparedness.
- The award ceremony will be conducted by King Carl XVI Gustaf during World Water Week in August 2025.
Detailed Insights
Blöschl’s career spans more than three decades, during which he has synthesized hydrological observations from the United States, Canada, Australia and Europe into a unified, openly accessible database. By correlating this dataset with long‑term climate indicators, he demonstrated that the intensity and recurrence of severe floods have risen markedly in the past few decades, exceeding historical baselines. These findings have been incorporated into the latest generation of predictive flood models used by national weather services and international aid agencies.
Beyond data aggregation, Blöschl founded the Doctoral Programme of Water Resources Systems at Vienna University of Technology, mentoring a new generation of scholars in interdisciplinary water‑resource management. He also holds a part‑time professorship at the University of Bologna, fostering cross‑border collaborations with former Stockholm Water Prize laureates such as Taikan Oki and Andrea Rinaldo.
Key Concepts
- Flood‑Risk Database: A comprehensive, geo‑referenced repository of historical and recent flood events, calibrated against climate variables.
- Climate‑Induced Flood Frequency: The empirically observed increase in the number of high‑magnitude flood events attributable to global warming.
- Predictive Flood Modelling: Computational tools that integrate hydrological, meteorological, and land‑use data to forecast flood extents and timing.
