Abstract

To explore the relationship between snow and streamflow droughts, we compiled a dataset of both and streamflow droughts in the Alps between 1961 and 2020 in 207 catchments. The dataset shared here the result of a newly developed bidirectionnal snow-to-streamflow drought propagation scheme, which identifies which snow droughts were followed by a spring/summer streamflow droughts and which spring/summer streamflow droughts were preceded by a snow drought. Each drought event is associated with information on its location, deficit, duration and timing.
In addition, we provide the code to run the snow-to-streamflow drought propagation scheme, in the form of a simple R function.
All details concerning the format of the data and indications on how to run the code are displayed in the readme file.

This folder contains a dataset with snow and streamflow droughts identified over the period 1961-2020 in Switzerland and Austria as well as a reproducible script to run a user-specific version of snow-to-streamflow drought propagation scheme with your own data.

Folder structure
	- readme.txt: description of the dataset
	- Shapefile: shapefile with the 207 catchments in which droughts were identified
	- Droughts:
		- Propagating_snow_droughts.csv: table with snow droughts identified to have propagated to a streamflow drought during subsequent spring/summer
		- Non_propagating_snow_droughts.csv: table with snow droughts that did not propagate
		- Preceded_streamflow_droughts.csv: table with spring/summer streamflow droughts identified to have been preceded by a snow drought during previous winter
		- Non_preceded_streamflow_droughts.csv: table with spring/summer streamflow droughts not preceded by a snow drought
	- Codes:
		- Functions.R: list of function in R to run the snow-to-streamflow drought propagation scheme
		- Propagation_scheme.R: R-script to run a user-specific snow-to-streamflow drought propagation scheme

Run of snow-to-streamflow propagation scheme:
	- Go to the Propagation_scheme file
	- Define all the parameters (pathways to data, drought identification parameters, list of stations/catchments)
		- Attention: your data must be csv-file each name witht the ID of the station/catchment in the format "ID.csv" and must have the following structure: ID / Year (YYYY) / Month (mm) / Day (dd) / Timestamp (YYYY-mm-dd)/Values
	- Run the scheme
