Streamflow data availability in Europe: a detailed dataset of interpolated flow-duration curves

[摘要] For about 24 000 river basins across Europe, we provide acontinuous representation of the streamflow regime in terms of empiricalflow-duration curves (FDCs), which are key signatures of the hydrological behaviour of a catchment and are widely used for supporting decisions onwater resource management as well as for assessing hydrologic change. In this study, FDCs are estimated by means of the geostatistical proceduretermed 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 acrossEurope. Consistent with previous studies, TNDTK is shown to provide highaccuracy for the entire study area, even with different degrees of reliability, which varies significantly over the study area. In order toprovide this kind of information site by site, together with the estimated FDCs, for each catchment we provide indicators of the accuracy andreliability of the performed large-scale geostatistical prediction.
