Former projects


The Stochastic Hydrogeology Group coordinates the ENSEMBLE project funded by the Swiss National Science Foundation. Its aim is to integrate the latest developments in the fields of alluvial geology, geostatistics, geophysics, numerical modeling, physics and mathematics to increase our ability to understand and predict complex hydrological systems. The project involve 6 universities in Switzerland and the US.


In this project, the aim is to understand groundwater flow and karst network formations in the region of Tulum, Mexico. This project is done in close collaboration with the Austrian Geological Survey in Vienna. The research questions are related to the processes that lead to the formation of one of the largest submarine karst system in the world.


Multiple point statistics, and especially the direct sampling technique can be used to model not only geological heterogeneity but also climatic variables. In this project, we test how the direct sampling can perform for those type of variables. This seems to be specially interesting since it requires a minimum effort of statistical inference.

World wide hydrogeological parameter database

You need an estimate of the porosity of a sandstone? or the specific storage a clayey sand? You need statistics about these parameters? It's often tedious to search for such values in books or papers. This is why we worked on developing an open and collaborative data base of world wide hydrogeological parameters. These parameters are classified by scale and rock types. You can consult the data at wwhypda.org.

Do not hesitate also to contribute, just fill a spreadsheet and upload it on the site to share your data with the world.

If you want to know more about the structure or detailed content, have a look at this paper.

Hydrogeologists Time Capsule

Have you ever wondered about the personalities of C.V. Theis, J. Bear, P. Whiterspoon or G. Dagan? All these famous hydrogeologists who changed the way we work. Since more than 10 years, we are collecting video interviews and publish them online. If you want to meet these masters, have a look at the Hydrogeologists Time Capsule web site. This is a project supported by the International Association of Hydrogeologists.
