Description of data

A detailed description of the dataset is provided in the data_description_analysis.pdf file. In particular, the methodology and stage-discharge rating curves are provided in this file. Stream data were measured in three locations from glacier snout (Station 1); after the outwash plain (Station 2) and at the end of the glacier forefield (Station 3) (see overview_GS.png). A shapefile is also provided (coordinate system LV95).

2 datasets are available in the data.zip file:

River_2019_2021_10T.csv : contains the measured River Electrical conductivity (EC) [μS/cm], Stage [meters] and Temperature [°C] data for all stations in a tidy data format (see pdf for detailed description), with a 10 minutes timestep.

Discharge2020_10T.csv & Discharge2021_10T.csv : contains the estimated discharge [m3/s] at Station 1 and Station 2 from July 2020 to October 2021 and estimated error (2 standard deviations) in a tidy data format (see pdf for detailed description), with a 10 minutes timestep.

Additionally, the point discharge measurements covering peak summer discharge to minimal winter baseflow are provided in the Point_discharge_measurements_2020_2021.xlsx file.

Plots of river parameters and discharge are also provided in data.zip for vizualisation.
