Alpine regions are among the most affected by climate change’s impacts.
In this presentation, I will show how water availability could evolve in the region of Tsanfleuron in the Swiss Alps. This site combines a rapidly retreating glacier overlying a karstic aquifer that feds a spring used for water supply by the municipality of Conthey. The characterization of the system involves several aspects, from estimating the volume of the glacier using geophysics and spatial statistics, to constructing several models allowing to forecast the evolution of water availability.
I will show that our preliminary assessment and models provide highly uncertain forecasts, and discuss how we could improve them.
Philippe RENARD leads the Stochastic Hydrogeology Group within the Centre for Hydrogeology and Geothermics at the University of Neuchâtel, Switzerland. His research focuses on quantitative hydrogeology and uncertainty quantification to support robust decision-making. It involves software development, fieldwork, data acquisition, and applications of these tools to a wide variety of hydrogeological environments and questions (contaminant transport, climate impact, saltwater intrusion processes, optimization of groundwater extraction, stochastic simulation of aquifer parameters and climatic data).
