The course is intended for students with interests and background in geotechnics, building materials, structures, energy systems, dynamics, and mechanics. With the observed climate changes with higher temperatures, more precipitation and probably higher storm activity, infrastructures have to be designed for projected climate changes. Settlements in the vicinity of steep slopes will be exposed to increasing risk for slope failures, slides in soil and rock, slush and snow avalanches. Trough lectures and field trips the course will focus on recognizing sites and terrain exposed to avalanches and slides, and how to plan and protect infrastructures for sustainability and for minimizing damage risk.
- Introduction to global warming phenomena, amplification effects in the Arctic
- Observation and modelling of temperature in the ground and soil thermal properties
- Design of infrastructures in the Arctic and in a changing climate
- Probability and consequences of natural hazards
- General information about avalanches: types, release mechanisms, snow stability evaluation methods, avalanche protection, snow physics, a computer program for avalanche simulation. Field trip and experiments devoted to rockfalls and avalanches
- Field trip devoted to observations of foundation types and frost related damages
- Planning and design of buildings and structures in snowdrift areas
Upon completing the course, the students will:
- describe weather and climate-related geological processes and geotechnical aspects connected to planning, design, and protection of infrastructures as buildings, roads, bridges, and pipelines in the Arctic conditions
- explain the impact of changing climate conditions on infrastructures in the Arctic
- interpret the influence of climate change on natural disasters as snow avalanches and soil slides and rockfalls
- examine the possibilities for alternative energy sources in remote Arctic areas and explain the principles of a borehole thermal energy storage (BTES)
- implement the basic elements of risk assessments towards engineering practice and structures in Arctic conditions.
- execute simple evaluations of natural hazards during areal planning and design of infrastructure
- estimate runoff distances for avalanches and rockfalls by applying simple analytical models and numerical simulation programmes (e.g. RAMMS)
- design finite element models and run numerical computations for different thermodynamic processes related to the stability of infrastructure in frozen ground.
- design and perform field experiments involving logistical operations, data collection using scientific instruments, and data processing
- write engineering reports and present the results on related issues
- read and critically discuss scientific literature
- manage group tasks and workload within the group when conducting a collective exercise.
The course extends over ca 5 weeks including compulsory safety training, and is run in combination with AT-801.
Learning activities consist of lectures, seminars, two field excursions, and fieldwork.
Through lectures students will be introduced to academic content of the course. Lectures are supplemented with exercises referring to “Anderson and Ladanyi, Frozen Ground Engineering” (2004). Fieldwork reports and a report from the numerical modeling of avalanches must be approved in order to sit the exam.
During field excursions the students will investigate different foundation presented in Longyearbyen and Pyramiden. The students will work in small groups, to train teamwork skills. Based on observations from field excursions, the students shall produce a joint report describing observed foundation types and structural failures cause by lack of maintenance and possibly due to warmer climate, and present this to the class.
Fieldwork on rockfalls and avalanches will take place in proximity of Longyearbyen. Each student group shall prepare and present a joint report on evaluation of zones exposed to rockfalls and/or avalanche hazards from the fieldwork.
- Total lecture and seminar hours: 50 hours.
- Fieldwork: 2 days.
- Field excursions: 3 days.
