Volumetric Water Content Measurements at Illgraben 2022

This dataset contains volumetric water content measurements, water level, and pressure for a location along the Illgraben debris-flow channel (46°18'34.92"N, 7°37'59.26"E). The measurements (165780 data points) were conducted during the 2022 debris-flow season (May to October) at a sampling rate of five minutes. The dataset specifically contains:

• At 0.25 m depth with an ECH2O EC-5 sensor: volumetric water content (VWC)
• At 0.45 m depth with an ECH2O EC-5 sensor: VWC
• At 0.65 m depth with a TEROS 12: VWC
• At 0.85 m depth with a TEROS 12: VWC
• At 0.80 m depth with a CTD10: water level (WL), temperature (T), electric conductivity (EC) and air reference pressure (Pref)

Please note that due to malfunctioning the CTD10 data was only available until 27 June 2022.
