Piezometry

Since fall 2008 the Sites company has installed, in four drillings C6, C20, C11 and C7, permanent piezometers each one performing one measurement every 10 minutes. The devices are connected to acquisition stations which directly transfer data toward the Geoazur laboratory by modem, once a day. Data are transferred in the form of electrical signals (in Volts) and need conversion to obtain piezometric levels and temperatures of the water table at each drilling.

The acquisition frequency and data accuracy allow a very satisfactory monitoring of the variations of the unconfined sandy table forming the landslide and thus of the hydrological response of the slope.



The detailed Technical Notes of the measurement equipment comprise:

- Installation schemes for the devices in Technical Note 1 appendix 1
- Wiring configurations in Technical Note 1 appendix 2
- Sensor installation notes in Technical Note 1 appendix 3
- Certificates of calibration in Technical Note 2 appendix 4
- Resulting charts of the recorded values in Technical Note 3 appendix 5
