Title: Streamflow and groundwater droughts for 70 catchments in the Central Alps

Contact: Corentin Chartier-Rescan, corentin.chartier@slf.ch

Description: This dataset contains drought events of groundwater (GW), streamflow (Q), precipitation (P) and P-ET (PET) for 70 catchments in the Central Alps retrieved with a variable-threshold method from daily time series.

Structure of the folder: 
	- a Extracted_events_per_variable_per_catchment.zip folder: contains drought events extracted for each of the four variables;
	- a GIS.zip folder: contains two shapefiles: (1) catchments with information on catchment characteristics (Catchment_outlines.shp) and (2) streamflow gauges and groundwater wells (Gauges.shp);
	- a ReadMe file.

Structure of each file in the Extracted_events_per_variable_per_catchment.zip folder:
	- "site_no": ID of the catchment considered;
	- "Date": Date of the event;
	- "XXXX": Variable (either Q,P,P-ET or GW); 
	- "YYYY": Year of the event;
	- "MM": Month of the event;
	- "DD": Day of the event;
	- "Threshold": Threshold used to extract event;
	- "event_id": ID of the event;
	- "start_date": Starting date of the event;
	- "end_date": Ending date of the event;
	- "duration": Duration of the event;
	- "deficit": Deficit from threshold;
	- "intensity": Intensity of the vent.

GIS folder: The two files can be linked through the catchment ID provided, which refers to the ID of the streamflow gauge.
