Abstract

We propose a formal classification scheme for streamflow droughts in humid-temperature climate regions. The classification scheme relies on an existing drought typology and assigns events to one of eight drought types - each characterized by a set of compounding drivers - using information about seasonality, precipitation deficits and snow availability.
To ensure generalizability, the classification scheme uses globally available data i.e. observed streamflow from the Global Runoff Database and hydro-meteorological time series from the ERA5-Land reanalysis including temperature, precipitation, and snow-water-equivalent (SWE).
Hydrological drought types include rainfall deficit droughts, which are exclusively caused by a prolonged lack of rainfall and possibly aggravated by high evapotranspiration; rain-to-snow-season droughts, caused by a rainfall deficit in the rain season continuing into the snow season; wet-to-dry season droughts caused by a rainfall deficit in the rain season that continues into the dry season; cold-snow-season droughts, caused by abnormally low temperatures in the snow season; warm-snow-season droughts, caused by abnormally high temperatures in the snow season; snowmelt droughts, caused by a lack of snowmelt discharge in snow-influenced basins; glaciermelt droughts, caused by a lack of glaciermelt; and composite droughts, caused by a number of drought generation mechanisms.

Hydrological drought classification in Europe

Authors: Manuela Brunner
Owners: Manuela Brunner
Last update: 26.09.2022

This dataset provides input data and an R-script to run the drought classification scheme proposed by Brunner et al. 2022 (Water Resources Research) for 817 catchments in Europe. 

Dataset components:

(1) Shapefile of 817 GRDC catchment outlets (GRDC 2019): GRDC_points.shp
Metadata information was derived from GRDC
(2) Shapefile of 817 catchment shapes with information on catchment characteristics derived from the GSIM data base and ERA5Land data: GRDC_shapes.shp
Metadata information derived from GSIM database (Do et al. 2018) and ERA5Land (Munoz-Sabater et al. 2021).
(3) R-script implementing the drought classification scheme: drought_typology.R
(4) Data needed to classify drought events for the 817 catchments:
(a) Streamflow droughts extracted from GRDC time series
(b) Precipitation deficits extracted from ERA5Land-derived precipitation time series
(c) Snow-Water-Equivalent (SWE) anomalies and time series
(d) Temperature time series
