Abstract

## README

### Data supplement to: "How the river network shapes spatiotemporal drought behavior across Europe"
**Joren Janzing, Niko Wanders, Steye L. Verhoeve-Dwars, and Manuela I. Brunner**

This dataset supplements the manuscript: "How the river network shapes spatiotemporal drought behavior across Europe" (Janzing et al, 2026) which is published in **Geophysical Research Letters**.
The manuscript studies the role of the river network in the spatial extent of droughts and uses simulations from the 30-arcsec PCR-GLOBWB2.0 model.

The dataset contains the data required to recreate the figures in the main manuscript.
It includes:
- Drought times series for discharge (QDrought.csv) and runoff (RDrought.csv), simulated with PCR-GLOBWB2.0.
- The locations of the subcatchment outlets and associated hydroclimatic characteristics (locs.csv)
- A shapefile for the different basins in Europe (basins.shp);
- A dictionary with grids with the river branch index of each river branch (branches.pkl) (needed for plotting, derived from PCR-GLOBWB2.0)
- A python notebook to recreate the main figures in the manuscript (river_networks.ipynb)
- Additional data for the supporting information: time series of runoff droughts without including water abstractions (natRDroughts.csv), discharge droughts in simulations (simulations.pkl) and observations (observations.pkl) from EStreams (do Nascimento et al., 2024) and discharge and runoff droughts from simulations without water bodies (QDroughts_nL.csv; RDroughts_nL.csv, respectively).
