This paper outlines the conclusion from an analysis of 18 large cave systems around the world, comprising more than 1500 km of conduits. The 3D geometry of complex cave systems have been analysed in relation to their geological context as well as their hyd ...

In order to define the safety conditions and the sustainable development of the large Triesenberg landslide (5 km(2)), the Principality of Liechtenstein has undertaken a modelling research to determine both the critical hydraulic heads and the potential influence of climate changes. The main objectives of this research focused on critical groundwater levels and related movements, in order to supply significant mid and long-term information for land planning. First a geological model was built to define the

Using advanced hydrogeological and geomechanical finite element modelling, it has been possible to model the mechanical behaviour of a large slope movement, the Triesenberg landslide. This slope is located along the Rhine valley in the Principality of Liec ...

Recent studies on the complex 3D geometry of large cave systems around the World allowed us to get statistical evidence of the inception horizon hypothesis. It clearly confirmed the idea that the development of karst conduits under phreatic conditions is strongly related to a restricted number of so called inception horizons. An inception horizon is a part of a rock succession that can favour the earliest cave forming processes (LOWE 1992).

The consideration of predicted climate change conditions in the hydrogeological and geomechanical modelling of a large landslide allows the assessment of its future behaviour in case of crisis. This application shows that the predictions are not necessaril ...
