Comprehensive investigations of climate change impacts on hydro-climatic extremes (droughts, floods, storms …) are just starting (and very
challenging) and are surely a topic for PIK (socio-economical impact, public interest)
RECCWEX
Central questions
• How will climate change-related extreme events manifest in certain regions under global change?
• Where are regional hot spots?
• Are new and never observed extremes possible?
• What is the feedback climate/vegetation/hydrology and how can this knowledge be used to design landscapes in order to counteract regional climate impacts?
• Where are the gaps in modeling to cover the research questions above?
• What is the range of uncertainty/confidence in regional scenarios of future extreme events?
• What are possible adaptation measures?
RECCWEX
Research goals
• Quantification of possible impacts related to meteorological and hydrological extremes in different regions/ climate zones;
• Vulnerability and possible adaptation measures;
• Development of a state-of-the-art model system;

1: Maps of flood-related damages in 2011-40 and 2041-70
Average flood damages per river reach and scenario period (considered are private houses and small enterprises). Projection of floods: hydrological model SWIM driven by regional climate models REMO and
CCLM (in total 7 climate realizations). Damage functions provided by the German Insurance Association (GDV). Average flood damages 1961-2000 = 100%.
First German wide estimation of flood related losses under climate change.

• Investigation of vulnerability and possible adaptation measures – “no regret measures”;
• Stronger link to the global scale;
• Stronger integration of “cities” and “health”.
