Abstract
Abstract. For about 24 000 river basins across Europe, we provide a
continuous representation of the streamflow regime in terms of empirical
flow-duration curves (FDCs), which are key signatures of the hydrological behaviour of a catchment and are widely used for supporting decisions on
water resource management as well as for assessing hydrologic change. In this study, FDCs are estimated by means of the geostatistical procedure
termed total negative deviation top-kriging (TNDTK), starting from the empirical FDCs made available by the Joint Research Centre of the European Commission (DG-JRC) for about 3000 discharge measurement stations across
Europe. Consistent with previous studies, TNDTK is shown to provide high
accuracy for the entire study area, even with different degrees of reliability, which varies significantly over the study area. In order to
provide this kind of information site by site, together with the estimated FDCs, for each catchment we provide indicators of the accuracy and
reliability of the performed large-scale geostatistical prediction. The
dataset is freely available at the PANGAEA open-access library (Data Publisher for Earth & Environmental Science) at https://doi.org/10.1594/PANGAEA.938975
