International audience; For many environmental applications, the interpretation of fiber-optic Raman distributed temperature sensing (FO-DTS) measurements is strongly dependent on the spatial resolution of measurements, especially when the objective

International audience; Heat is known to be an excellent tracer for characterizing groundwater flows in the sub-surface. Steady-state hydraulic conditions are often assumed to derive groundwater flows components from temperature measurements. Here, w

International audience; Heat has been proposed as an excellent tracer for monitoring groundwater flows, especially in karstic aquifers which are characterized by rapid and localized flows. Here, we present some experiments that demonstrate the intere
