Summary:•Paleoflood hydrology document the variability of past floods in time and space.•Reconstructed flood chronologies and magnitude are more and more robust.•The diversification of paleoflood archives results in large available data sets.•Paleoflood data can provide substantial socio-economic benefits.•Perspectives in paleoflood hydrology are outlined. Assessments of present and future flood hazard are often limited by the scarcity and short time span of the instrumental time series. In pursuit of documenting the occurrence and magnitude of pre-instrumental flood events, the field of paleoflood hydrology emerged during the second half of the 20th century. Historically, this field has mainly been developed on the identification and dating of flood evidence in fluvial sedimentary archives. In the last two decades, paleoflood hydrology approaches have also been deployed to investigate past floods contained in other natural archives. This article reviews major methodological and technological advancements in the study of lake sediments with the aim to showcase new, robust and continuous paleoflood series. Methodological advancements of flood archives such as tree rings and speleothems are also addressed. The recent developments in these fields have resulted in a growing paleoflood community that opens for cross-disciplinary analysis and synthesis of large data sets to meet the pressing scientific challenges in understanding changes in flood frequency and magnitude.
