The present report was commissioned by the Conference of Rhine Ministers in 2020 to update the ICPR climate change adaptation strategy by 2025. The focus here is on the discharge regime (high and low water) and the water temperature. As a result, the expert group ‘Water temperatures’ (EG STEMP) has been given the task of updating the ICPR technical report no. 209 on the long-term development of water temperatures in the Rhine by the end of 2024. The report is only available in German, French and Dutch.
