Abstract The paper compares the results from a range of GCM scenarios, downscaling methods and hydrological simulation techniques that have been applied to assess the impact of climate change on rivers in Wales. In spite of wide differences in scenarios and the sophistication of the methodology, there is broad agreement.

Key words climate change impacts; downscaling; river regimes; Wales
