The sensitivity of fluvial flood risk in Irish catchments to the range of IPCC AR4 climate change scenarios

► Sensitivity of fluvial flood risk to climate change is assessed for irish catchments. ► Impact of climate change is not as great for flood peaks with smaller return periods. ► Flood peaks are significantly less sensitive to PET than to rainfall scenarios. ► A progressive increase in the peak flow for irish river catchment when moving from the 2020s to the 2080s.
