This study reconstructs the main flood phases in central Europe from event layers in sediment cores from Holocene Eifel maar lakes and Pleistocene dry maar structures. These reconstructions are combined with recent gauge time-series to cover the entire precipitation extremes of the last 60 000 years. In general, Eifel maar sediments are perfectly suited for the preservation of event layers since the deep water in the maar lakes is seasonal anoxic and therefore, bioturbation is low. However, the preservation of annual lamination is only preserved in Holzmaar and Ulmener Maar; the other cores are dated by 14C, magnetostratigraphy, tephra markers and ice core tuning. The cores were drilled in the Eifel region of central western Germany, which represents a climatic homogenous region from Belgium to Poland and all across Central Europe.A total of 233 flood layers over 7.5 mm were detected in all analysed cores. The stratigraphic classification of the flood events follows the newly defined Landscape Evolution ... : Sediment core combination: AU2 (Aueler Maar Lat.: 50.28383, Long.: 6.59574. elevation: 453, recovery: 123 m, Gauß-Krüger coordinate system: 2542455/5572017) + HM1 (Holzmaar Lat.: 50.1203, Long.: 6.87963, elevation: 425, recovery: 10 m, Gauß-Krüger coordinate system: 2562900/5554030) ...
