Streams and rivers emit substantial amounts of nitrous oxide (N2O) and are therefore an essential component of global nitrogen (N) cycle. Permafrost soils store a large reservoir of dormant N that, upon thawing, can enter fluvial networks and partly degrad ...
The presence of an artesian aquifer lying under the construction site of a hydro-electrical power plant had not been considered in the design project. The foreseen excavation works could not be carried out due to a high risk of hydraulic heave of the excav ...
The mountain cryosphere of mainland Europe is recognized to have important impacts on a range of environmental processes. In this paper, we provide an overview on the current knowledge on snow, glacier, and permafrost processes, as well as their past, curr ...
In high mountain hydrosystems, glacial meltwater composition is potentially affected by the degradation of alpine permafrost terrains and ground ice bodies releasing atmospheric pollutants that have been stored in permafrost terrains for several decades. I ...
Knowledge of surface hydrology is essential for many applications, including studies that aim to understand permafrost response to changing climate and the associated feedback mechanisms. Advanced remote sensing techniques make it possible to retrieve a ra ...
This thesis analyses the impacts of climate change on Swiss tourism. It looks in particular at the regional vulnerability, adaptation, and barriers that hinder this process. The final goal of the work is to make a contribution in bringing about a smoother ...
Monitoring of the periglacial environment is relevant for many disciplines including glaciology, natural hazard management, geomorphology, and geodesy. Since October 2022, Rock Glacier Velocity (RGV) is a new Essential Climate Variable (ECV) product within ...
Water flow in a natural snow cover is generally a complex process because of the strongly stratified and changing structure of the snowpack. Important differences in, for example, density and grain size between layers cause sometimes very sharp transitions ...
In this work, we analyze the vulnerability of tourism to climate change in 53 Swiss alpine regions. We analyzed in particular the impacts generated by changes in climate suitability for tourism activities, snowpack reduction, glaciers melting, permafrost m ...

Permafrost consists of soil and rocks that remain at 0 degrees C or below for at least two consecutive years. In mountains, permafrost ground ice acts like cement, stabilizing rock walls. Its degradation, following climate warming, may lead to slope instab ...
