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)
Land use change
CCLM/ STAR (and other)
Regional climate model
1) Water resources and extremes
2) Change in vegetation dynamics (crop production)
Water resources management
Agriculture and forestry
Floods, droughts, storms …
Huang S, Hattermann FF, Krysanova V, Bronstert A (2011) Projections for climate change affected river flood conditions in Germany by combining three different RCMs with a regional hydrological model. Submitted to Climatic Change.
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.
+ ~3.02. Flood related damages in Germany per period
Hattermann FF, Huang S, Burghoff O, Willems W, Österle H, Büchner M, Kundzewisz ZW (2011) Modeling flood damages under climate change – a case study for Germany [Resutls of the GDV insurance project]. Submitted to Natural Hazards.
Projection of flood related damages on private houses and small enterprises: SWIM driven by the regional climate models REMO and CCLM (7 climate realizations in total). Damage functions provided by the German Insurance Association (GDV). 500 Million Euro is the observed and simulated average in the reference period 1961-2000
