MSc opportunity: Monitoring progressive damage accumulation at the Bedretto Tunnel, Switzerland

Project Framework and Goals The Furka-Oberalp railway line presents the only year-round east west connection in the Swiss Alps. It serves to link the resort areas of Valais, Central Switzerland, with those in the Grisons, as well as efficient local transportation. Construction of the Furka (Base) Tunnel began in 1972 and was completed in 1982. […]

MSc Stefanie Diener: Environmental controls on bedrock fracturing and rockfall production adjacent to the rapidly thinning Schmiedingerkees glacier (Hohe Tauern Range, Austria)

Candidate: Stefanie Diener Supervisors: Kerry Leith, Dr. Matthew Perras, Ingo Hartmeyer (GEORESEARCH Forschungsgesellschaft mbH) Institution: ETH Zurich Activity: Beginning Fall 2017 Since 1880 mean annual air temperatures in Austria have risen by 2 °C, more than twice the average global warming of 0.85 °C. Glacier retreat has evolved into one of the most visible consequences of this climatic change […]

MSc opportunity: The relationship between large-scale geomorphological processes and local slope instabilities affecting transport networks

The construction of transportation routes can markedly increase the risk of rockfalls and landslides in Alpine settings. Where forming road and rail routes involves excavation or the construction of embankments in locations already in a state of critical stability, minor changes to slope geometry or groundwater conditions can have a notable impact on local ground […]

MSc opportunity: Monitoring progressive fracture propagation in response to environmental stress variations

Exceptionally warm summer temperatures in northern Europe during the summer of 2014 were accompanied by active fracturing and small rockbursts from flat-lying postglacial bedrock surfaces on a small Finnish Island. Employing a new portable acoustic emission detection system, this project will investigate the correspondence between key environmental variables (air and rock temperature, humidity, wind, and […]

MSc Martin Kradolfer: The role of ice filled cracks on rock slope stability – a laboratory study

Candidate: Martin Kradolfer Supervisors: Florian Amann, Kerry Leith Institution: ETH Zurich Activity: Beginning Fall 2017 Project Framework: Ice filled tension cracks are commonly observed in association with active or catastrophic rock slope failures located in potential permafrost regions of the Alps. Displacement or dislocation along cracks in many of these rock slopes has been observed to primarily occur […]

BSc opportunity: Assessment of deep-seated landslide distributions in the Alps (Two possible topics: Valais and Ticino)

Gaining a better understanding of processes that contribute to the formation of large rock slope failures can provide important insight into their mechanics and future development throughout the Alps. Such instabilities are commonly assumed to be initiated as a result of erosion, seismic activity, or a change in rainfall patterns. They are not have not […]

BSc opportunity: Characterisation of >300 rainfall-induced landslides on a major transport route in the Bhutan Himalaya

Gaining a better understanding of factors that contribute to the location of rainfall-induced landslides affecting alpine transport networks is an important first stem in protecting against such events, and maintaining access to critical regions during intense weather events. Three days of late monsoon rainfall in the Bhutan Himalaya this year generated an unprecedented degree of […]

BSc opportunity: Processing of acoustic emission (AE) data from an exfoliation fracture formed in response to high temperatures in the Finnish Archipelago

Exceptionally warm summer temperatures in northern Europe during the summer of 2014 were accompanied by active fracturing and small rockbursts from flat-lying postglacial bedrock surfaces on a small Finnish Island. Employing a new portable acoustic emission detection system, this project will investigate the correspondence between key environmental variables (air and rock temperature, humidity, wind, and […]

BSc opportunity: Robust Sensor Infrastructures for Environmental Monitoring

The global increase in atmospheric temperature may be accelerating the physical breakdown of landscape and infrastructure. Rock expands when heated, and combined with other stresses in the landscape associated with topography and regional tectonic history, can potentially trigger the formation of large rockfalls. Recently, large bedrock outcrops in California and Finland hosted dramatic fracturing events […]
