My research activities focus on the characterisation of flow in karst carbonate rocks, using a naturalistic approach (field geology and geomorphology) and a quantitative approach (temporal and spatial evolution of the physico-chemical properties of groundwater, numerical modelling). This work requires the acquisition of data and in-situ observations, at the surface outcrop or by speleological explorations in the endokarst. The data is then interpreted to characterise the hydrodynamic functioning of the aquifers. Finally, numerical modelling of flow and transport processes is used to deconvolute the signals and validate the conceptual models previously established. The methodologies developed are implemented on examples from the Mediterranean region and more particularly in carbonate Lower Provence (coastal and continental zones).
