This paper summarises the results of the study “Climate change and water management – a focus on floods and droughts” which presents the current state of knowledge of climate change with regard to the effects on water management in Austria. Average evaporation in Austria has increased by about 80 mm/yr over the past three decades, similar to annual rainfall. The increasing trends in measured flood discharges have become somewhat more frequent in recent years, while the decreasing trends of measured low flows have weakened to some extent. Climate projections suggest some increases in floods, but these are much smaller than the natural flood variability. In the Alps, significantly higher winter runoff is expected. In the lowland regions of eastern and southern Austria, low flows will possibly decrease. Overall, the findings are similar to those of the previous study from the year 2011. Some additional recommendations are given.
