OZCAR Research Infrastructure


Observation of groundwater


Contributing to the development of OZCAR observatories

My contribution to the development of research observatories spans several decades, combining the establishment of new field sites, the design and implementation of long-term monitoring systems, field experimentation, scientific coordination and data valorisation. From the Maheshwaram watershed in India, where I coordinated the development of an observation system for a fractured-rock aquifer, to karst and hard-rock observatories in France, India and Africa, I have helped build the long-term observational basis needed to understand groundwater flow and aquifer functioning.

Through my involvement in observatories integrated into national research infrastructures, including OZCAR and SNO H+, I have contributed to connecting sustained field observations with scientific interpretation, modelling and the production of reusable research data.
