Description :
This project focuses on understanding karstic systems and particularly on the issue of recharge and transfer processes in these very heterogeneous and generally inaccessible environments. The objective is to use the fiber optic technique to identify the recharge points of the karstic aquifer of Fourbanne (25) by measuring the temperature of the water continuously along the conduit/cavity, and ultimately to propose a hydrogeological model of the flow constrained by thermal observations.

Data acquisition methods :
  • Experimental data :
    Way to obtain data: collect of data obtained at the level of the digitizer of an optical fiber installed in the underground cavity along the 850m long conduit. The digitizer measure all the 5min with a sampling of 50CM.
    How it works?
    The fiber is made of silica. Depending on the temperature, it will see its molecules vibrate (due to the heat). The light injected into the fiber will interact with these molecules in vibration (more precisely photon-electron). This phenomenon will generate a return of light, but in a changed way (shift in photon frequency). Depending on the more or less significant shift in frequency, we are able to measure the temperature (via digitizer).
    This phenomenon is called Raman back scattering.
