Climatic change and the effect on hydrology and water management in the Rhine basin.
There has been a marked increase in recent years in the resources dedicated to investigating the problems arising from climate change with respect to hydrology and to some extent to water resource management. Many of these studies are concentrated on the river Rhine basin. In order to review the actual state of scientific findings a workshop, organised by the International Commission for the Hydrology of the Rhine (CHR), was held on 24 and 25 June 2003. The invited experts discussed the following topics: observed variability in climatic and hydrological data, the development and interpretation of climate scenarios, and assessment of changes in the discharge regimes and the occurrence of hydrological extremes. Based on the workshop the question of whether or not current knowledge and procedural strategies can be used as a basis for future water management was evaluated by an expert group of the CHR. In this paper the process of decision-making with regard to flood management is analysed. Hints are given to convince the decision-makers to take into account the impacts of climate change in water resources management. The special challenges arising in international river basins are discussed.
