 This study examined how climate change would affect the flow regimes of rivers in Europe. The results showed that climate change could lead to significant changes in the timing and magnitude of river flows in certain regions. For example, in the Mediterranean region, climate change was predicted to reduce snowpack and decrease winter precipitation, resulting in less spring runoff and more summer droughts. In contrast, in the boreal climate zone, climate change was predicted to increase precipitation and snowpack, leading to higher spring runoff and lower summer droughts. Additionally, climate change was predicted to cause decreased flow magnitudes in the temperate climate zone, while increasing flow magnitudes in the boreal climate zone.
