Welcome

Main fields in Hydrogeology:

- Fractured Hydrogeology in Crystalline rock Aquifers: hard rock

• well test hydraulics (anisotropy in fractured hard rocks)
• interpretation of pumping tests in fractured crystalline aquifers,
• estimation of natural recharge and water budget at the watershed scale (Double Water Table Fluctuation method)
• sustainable management of groundwater resources in hard-rock areas
• forest hydrology / hydrogeology
• weathering processes and chemical fluxes, groundwater flows
• interaction between tunnels and groundwater in mountains
• water flow and temperature anomaly through a vertical fracture in mountainous crystalline rocks
• mountainous hydrogeology
• 3D modeling of groundwater flows and temperatures in mountainous regions
• hydrogeo-psychology: the sunk cost fallacy of deep drilling

- Karst Hydrogeology in Carbonate rock Aquifers:

• karst flash flooding
• interpretation and modeling of pump tests in karst systems
• water flows in karst conduits

 

Regions of interest:

- Hard-rock areas in Southern India : Andhra-Pradesh (Maheshwaram Watershed) and Karnataka States (Mule Hole Watershed)

- Mediterranean Karst Systems in Southern France : Fontaine de Nîmes Spring and Hérault Karst Systems
