Global Streamflow Drought Dataset Version 1

The Global Streamflow Drought Database (GSDD) provides basin-scale streamflow drought event information for 2,998 gauging stations worldwide, with records available from 1950 onwards. It also accounts for human influence; drought events are provided separately for unregulated catchments and regulated catchments (i.e., catchments with upstream dam presence). The length of the observational period varies across stations, ranging from 20 to 74 years. The complete dataset is distributed as a compressed archive (Global Streamflow Drought Database.zip), organised into three primary subdirectories along with accompanying metadata files in Excel format. Site ID prefixes denote data sources: WRIS_ refers to India-Water Resource Information System, CANADA_ refers to HYDAT (Water Survey of Canada), GRDC_ refers to the Global Runoff Data Centre, and USGS_ refers to United States Geological Survey.
