My research focuses on the behavior of aquifer systems, with a particular interest in fractured crystalline aquifers, karst aquifers, and coastal karst aquifers. It combines field observations, hydraulic tests, hydrochemistry, tracer studies, data analysis, and modeling.

Fractured crystalline-rock aquifers

My work on fractured crystalline aquifers aims to understand the role of fracturing and zones of alteration in groundwater flow. Hydraulic tests, logging, and flow measurements allow me to characterize permeability distributions and identify the most conductive structures.

Karst aquifers

I have also studied the behavior of karst aquifers, which are characterized by high heterogeneity and flow rates that can be very rapid.

The study of karst floods reveals the various flow paths and mechanisms of water transfer within the system. Pumping tests provide another perspective, allowing us to explore the hydraulic properties and connections between the various karst structures.

Coastal karst aquifers

Finally, my research focuses on coastal karst aquifers, at the interface between groundwater, seawater, and coastal ecosystems. Underwater springs provide ideal vantage points for observing these interactions.

The Vise submarine spring, in the Thau Lagoon, is a particularly remarkable example. My study of it led me to investigate the phenomenon of “inversac,” during which the hydraulic flow of the spring can reverse: lagoon water then flows into the karst system.

These various studies are part of a single approach: understanding how complex aquifer systems function by combining observations, methods, and approaches from multiple disciplines.
