Rijkswaterstaat 2 International Commission for the Hydrology of the Rhine Catchment(CHR)
• Founded in 1970 the framework of the International Hydrological Decade of UNESCO • Co-operation on the basis of a memorandum of understanding (‘Note Verbale’) between the Ministries of Foreign Affairs of the member states
• http://www.chr-khr.org/
Rijkswaterstaat 3 International Commission for the Hydrology of the Rhine Catchment(CHR)
• Since 1975 co-operation in the framework of the International Hydrological Program (IHP) of UNESCO and the Hydrological Water Resources Program (HWRP)), of WMO
• Today co-operation of hydrological institutes in the Rhine basin
Rijkswaterstaat 4 Mission and tasks
CHR initiates and carries out hydrological studies for sustainable development of the Rhine basin and makes the results of these studies available to responsible authorities in the Rhine riparian states and to the EU. This way CHR tries to contribute to the development and evaluation of water management strategies.

Rijkswaterstaat 6 CHR - subject
• Extension of knowledge about the hydrology of the Rhine basin • Contribution to solving cross-border problems
• Data base Precipitation / discharge • Sediment transport • Discharge regime 1900 – 2000, can we see trends?
Rijkswaterstaat 7 Discharge regime Rhine 20th century
Rijkswaterstaat 8 CHR - subject
• Extension of knowledge about the hydrology of the Rhine basin • Contribution to solving cross-border problems
• Data base Precipitation / discharge • Sediment transport • Discharge regime 1900 – 2000, can we see trends? • Discharge regime and climate change, results are input to ICPR
Rijkswaterstaat 9 RheinBlick2050 Development of joint climate and discharge projections for the international Rhine River catchment

Rijkswaterstaat 65 CHR meeting, 26/27 May 2010, Alkmaar (NLD) 10 10 Source: BfG Rijkswaterstaat 11 Conclusions ... so far ... • Wetter winters, dryer summers • Increase of winter, decrease of summer discharge • Average changes more robust than changes in the extremes • Homogeneous directions of change • Results do not contradict existing work
• However no smaller bandwidth
• Input for the scenario choice Rhine Commission (ICPR) Rijkswaterstaat 12 12 Climate scenario report ICPR
