It is expected that climate change will increase the intensity and frequency of precipitation in the Rhine river basin. Precipitation directly influences high water levels in the river. Our research compared the results of a large ensemble of climate model simulations for discharge at Lobith and two case studies in Germany.
The results for the German case studies show that flood risk will increase with 90% at the end of the 21st century, as compared to the current flood risk. Furthermore, the results show that a large part of the uncertainty spread can be contributed to natural climate variability.
To communicate about these results we have used the 3D interactive game “Sustainable delta”. This game allows water managers to develop adaptation measures for a hypothetical river basin. The effects of these measures is calculated by a computer model, using climate change scenarios. The game fosters the understanding of uncertainties by water managers and directly shows the effects of the measures.
