Floods are among the most destructive natural disasters, and robust knowledge about their past, present and future trends is therefore crucial for the sustainable development of societies worldwide. Paleoflood deposits in lacustrine sedimentary sequences enable the continuous reconstruction of flood variability at centennial to millennial scale beyond instrumental hydrological datasets. FLOODARC MSCA project (2019-2021) aims to provide a more comprehensive understanding of the long-term flood variability in the Iberian Peninsula by investigating flood archives in several Spanish lake records. Preliminary results show a see-saw pattern in flood frequency variability during the Medieval Climate Anomaly and the Little Ice Age transition with more (less) flood events occurring during cold (warm) phases in Atlantic and Mediterranean areas respectively. These dissimilarities seem to be controlled by the hydroclimate variability at the regional scale as well as by historical land use changes in different areas of northern Spain.
