The UKCEH Flood Event Data Suite consists of: - a procedure to identify and extract paired rainfall-high-flow events from paired time-series, - the dataset of 174,450 events identified when applied to open-access UK precipitation and flow data for 1203 river gauging stations and their upstream catchments, - a database of 63 rainfall statistics and runoff signatures derived from those events. Full details about this dataset can be found at https://doi.org/10.5285/663b9078-ff16-48b2-a3d0-a87f98d1143f
