High-frequency monitoring of discharge, electrical conductivity and temperature of flows from the low noise underground laboratory (LSBB – unsaturated zone of the Fontaine-de-Vaucluse karst system)

Dataset description

We provide high-frequency measurements of discharge, electrical conductivity and temperature of 12 flow points, 4 of which perennial, from the galleries of the low noise underground laboratory (LSBB). 

The following parameters are provided at hourly time step from July 2022 to April 2024:

  • Water electrical conductivity and temperature measured with a C4E probe from Ponsel;
  • Water discharge measured with a homemade flowmeter consisting in a plexiglass tube with a pressure sensor (PFT sensor from Sick) at the bottom.

The data was acquired at the LSBB site, which is part of the French network of hydrogeological observatories H+ (http://hplus.ore.fr/en/).

The data may be downloaded from the links provided below. The full dataset of the LSBB site is available from https://hplus.ore.fr/en/lsbb/.
