The SISKA, in collaboration with the Natural Hazards Unit (UDN) of the Canton of Vaud, has developed a methodology for classifying sinkhole subsidence phenomena in relation to geology, buildings, the presence of water, knowledge of the terrain and the presence or planned siting of structures in these sensitive areas.

With a focus on extreme events in karst environments, the SISKA's annual report provides information on our Institute's activities and suggests ways in which we can better understand the links between karst and anthropogenic climate change. We hope you enjoy reading it.

The SISKA congratulates Amir Sedaghatkish, a doctoral student at the SISKA, on the publication of his latest article in the Journal of Geophysical Research: Earth Surface! The article, entitled "Modeling Heat Transfer for Assessing the Convection Length in Ventilated Caves", provides an overview of the fundamental research on underground climate carried out by the SISKA as part of the Thermokarst project.

As part of the Thermokarst project, Claudio Pastore, a doctoral student at the SISKA, is studying the use of carbon dioxide as a tracer in ventilated caves. His latest results have just been published in the International Journal of Speleology under the title "Dispersion of artificial tracers in ventilated caves". Congratulations on this important milestone!

The SISKA and the Chrono-environnement laboratory (a CNRS joint research unit) have signed a research partnership agreement to continue their long-standing collaboration. This now promotes scientific exchanges between the two institutions on the theme of "Aquatic Ecosystems and Uses", with a particular focus on "Groundwater" and "Climate Change". The SISKA frequently works with the University on specific courses in karstic engineering, as well as on thesis and master's projects.
