Topic: A Cool Look at Hydroclimatic Risk

Speaker: Demetris Koutsoyiannis

Time: 9:30-12:00am July 12, 2025

Venue: Meeting Room A901, IGSNRR

Brief Introduction to the speaker:

Demetris Koutsoyiannis is a professor emeritus of Hydrology and Analysis of Hydrosystems in the National Technical University of Athens. He has served as Dean of the School of Civil Engineering and Head of the Department of Water Resources and Environmental Engineering. 

He has been awarded the International Hydrology Prize–Dooge medal (2014) by the IAHS, UNESCO and WMO, and the Henry Darcy Medal (2009) by the EGU. He has published about 1,200 research and education items, 270 of which in refereed scientific journals. His works have received 22,500 citations in Google Scholar and 12,250 in Scopus (h-index 76 and 60, respectively).

Brief Introduction to the report:

The allegations of climate crisis have sparked global concern. This presentation reexamines these claims from a fresh perspective by analyzing global and regional hydrological data. Mediterranean and Greek records show no consistent trends for rainfall extremes, highlighting natural variability. 

Using tools like the climacogram and K-moments, the study promotes robust risk analysis via multi-scale fluctuation assessments. Greek case studies on drought management and design rainfall support adaptive, stochastics-based strategies over deterministic models. It calls for a rational, evidence-based reassessment of climate narratives and risk management.
