Who we are / what we do
• Center for Environmental Systems
Research at the University of Kassel
• WaterGAP – a global model of water
availability and water uses
• European-wide probabilistic
assessment of climate change impacts
on river discharge (18 catchments)

Current status / recent progress
• Response surface method
• Impact of climate change (T and P)
on river discharge
• Change in T and P uniform over time
• Change in T and P differs with seasons
(critical seasons)

Points of concern

Center for Environmental Systems Research, University of Kassel, Germany
Points of concern
• Aggregate climate info to basin size
• Need climate info to “adjust” response
surfaces (extend study / zoom in)
• Difference to multi model simulations:
“seasonality” (JJA vs. individual months)

Plans for the next phase /
contributions to deliverables and milestones
• M6.14: Completion of preliminary probabilistic assessments of climate
change impacts using calibrated impact models:
Month 42
• Major milestone 6.4: Completion of probabilistic assessments of climate
change impacts, and impacts at seasonal to decadal timescales for the core
activities: crops, water resources, forests, energy, insurance and human
health.
