Climate change and river flow
- Long-term trends in river flows due to climate change are difficult to detect due to substantial inter annual and decadal variability as well as modifications to natural water flows arising from water abstractions, man-made reservoirs and land-use changes. Nevertheless, increased river flows during winter and lower river flows during summer have been recorded since the 1960s in large parts of Europe.
- Climate change is projected to result in strong changes in the seasonality of river flows across Europe. Summer flows are projected to decrease in most of Europe, including in regions where annual flows are projected to increase.
