Wasserextreme werden in Deutschland zunehmen. Dringend müssen Anpassungsstrategien entwickelt werden, um die Auswirkungen und Schäden durch Wasserextreme zu reduzieren.
Der Film begibt sich auf eine Spurensuche durch ganz Deutschland.

There’s a big gap between intending to adapt to floods and actually doing it. Our two-wave survey in Central Vietnam shows intention alone doesn't predict action. Policies must go beyond boosting intention to truly drive change. Hear more from Tang Luu (PICO4.8, Fri, 8:59)! #EGU25 #adaptation

Italy’s flood risk assessments estimate only how many were affected, missing the indirect broader human impacts (eg psychological distress). Our 2022 Marche flood survey shows their significance for both directly and indirectly affected residents. Chat with Sara Rokaj on Fri, 8:57 at PICO4.7! #EGU25

How do past floods shape future preparedness? While flood-affected households expect future impacts, they don’t always see them as more severe. The key to better adaptation? Boosting self-efficacy and social support, not just risk awareness. Learn more from Dominic Sett (PICO4.6, Fri, 8:53). #EGU25

Severe floods impact mental health, but what about long-term recovery? After Germany’s 2021 floods, PTSD symptoms dropped from 28% to 17% over 3 years. Our modeling reveals who recovers and how we can better support future survivors. Find out more at Marie Zenker’s poster! (10:45, X3.65). #EGU25

Severe floods can worsen mental health — and overlapping crises like COVID-19 can amplify the impacts. In 2020, communities in Hue City, Vietnam, faced both. We surveyed 400 people in Oct ‘23 to understand their experiences. Hear what we found at My Pham’s talk today, 9:27am, Room 1.31/32. #EGU25

The July 2021 flood in Wallonia offers critical insights into flood risk management. How many people received a warning? How did people interpret and trust warnings, and how did they respond? Heather Murdock presents findings in a PICO session on Wednesday, 8:49, PICO 3.8! #EGU25 #floods

A new machine learning tool, FlooDEsT, estimates building-level damage from urban pluvial flooding. Trained on real-world flood data, it offers faster, more accurate damage estimates compared to traditional models. Find out more at Guilherme Mohor’s poster (Wed, 8:30–12:30, X3.26)! #EGU25 #floods

Don't miss Annegret Thieken's medal lecture (Tue, 10:45, N2)! Learn how post-disaster household surveys have helped improve flood risk management, the ethics of collecting data from affected communities, and how different flood types influence impacts and coping mechanisms in Germany. #EGU25 #floods
