报告内容简介：

There is serious concern that the probability of droughts and floods is increasing over time. This presentation will review recent findings on the magnitudes and mechanisms of drought and flood changes. Droughts and low flows in Europe will be related to long term variability of climate modes, precipitation and evaporation. The role of the seasonality of the drivers of droughts will be emphasized. Flood changes are examined in the light of the role of land-use change, such as deforestation, urbanisation and soil compaction by agriculture; hydraulic interventions, such as river training, levees and dams; and climate change effects. Changes of floods as resulting from the seasonal interplay of soil moisture, snow and extreme precipitation via runoff generation are attributed to their drivers. Finally, joint changes of low flows and floods are evaluated.
