Catalog of historical hydrological droughts and runoff events for the Elbe subcatchments

Overview This catalog was developed within the framework of the project ElbeXtreme. This document describes two hydrological event catalogs developed for German catchments: Drought Event Catalog Runoff Event Catalog Both catalogs are derived from processed daily discharge data from CAMELS-DE and CARAVAN-DE, with catchment and water quality attributes provided by the QUADICA dataset (Ebeling et al., 2022). For detailed explanation of the event identification methods please refer to Giani et al., 2022 and Saavedra et al., 2024. Ebeling, P., Kumar, R., Lutz, S.
