Distributed Temperature Sensing as a down-hole tool in hydrogeology

Papers - Publications scientifiques

Distributed Temperature Sensing (DTS) technology enables down-hole temperature monitoring to study hydrogeological processes at unprecedentedly high frequency and spatial resolution. DTS has been widely applied in passive mode in site investigations of groundwater ow, in-well flow, and subsurface thermal property estimation. However, recent years have seen the further development of the use of DTS in an active mode (A-DTS) for which heat sources are deployed. […]

3rd AGU-SEG Hydrogeophysics Workshop: Imaging the Critical Zone

  The 3rd AGU-SEG Hydrogeophysics Workshop – Imaging the Critical Zone – will be held in Stanford, California, next 24-27 July 2017.   The Critical Zone (CZ) is a dynamic region where rock, soil, water, air, and living biota interact to shape Earth’s surface. The Critical Zone ranges from the tops of the trees to the bottom of groundwater. The field […]

Contribution of Magnetic Resonance Soundings for characterizing water storage in the unsaturated zone of karst aquifers

Papers - Publications scientifiques

Understanding the role of the unsaturated zone in aquifer recharge and contaminant attenuation processes is a major challenge for the protection and management of karstic water resources. We present the potential of the MRS (Magnetic Resonance Soundings) geophysical method for characterizing the vadose zone of karst aquifers composed of epikarst and infiltration layers. To investigate the hydraulic functioning of the Durzon karst system located […]

Hydrogeophysical characterization of transport processes in fractured rock by combining push-pull and single-hole ground penetrating radar experiments

Papers - Publications scientifiques

The in situ characterization of transport processes in fractured media is particularly challenging due to the considerable spatial uncertainty on tracer pathways and dominant controlling processes, such as dispersion, channeling, trapping, matrix diffusion, ambient and density driven flows. We attempted to reduce this uncertainty by coupling push-pull tracer experiments with single-hole ground penetrating radar (GPR) time-lapse imaging. The experiments involved different injection fractures, chaser […]
