GEO-3135 Rock-slope failures: Geology, hazard and monitoring - 10 stp

Within the scope of this course the students will get theoretical and applied training in hazard assessment and monitoring of unstable rock slopes. The course builds on the students prior geological knowledge, and aims to give a wide ranging understanding of rock-slope failure theory, from rock mechanics, structure and kinematics, to landslide types and hazard characterisation.

Students will learn about and apply methods for characterisation of unstable rock slopes including field mapping, desktop mapping, drone technology and photogrammetry, monitoring and instrumentation and remote sensing methods. Furthermore, students will learn how to characterize and assess the slope hazard (and secondary effects) using numerical modelling techniques and the Norwegian risk assessment system.

The field course component will introduce the student to multiple types of rock-slope hazards in the dramatic north Troms mountain environment. Practical exercises and field investigations will give the students a systematic approach to the topic.

Bachelor's degree in geology, or a similar degree following a programme of study of at least three years, or similar education approved in accordance with the Norwegian Universities Act section 3-4. In addition, specialization in geology worth the equivalent of at least 80 ECTS credits is required. Normally, an average mark of C or better is required at the bachelor's degree level or other program for basis of admission.

Application code: 9371.

Knowledge

The student has

• a comprehensive understanding of rock-slope failure theory, including rock mechanics, structure and kinematics, slow rock-slope deformation, and types of rapid rock-slope failure.
• understanding of landslide, hazard and risk terminology.
• knowledge of all types of geohazards that result from rock-slope failure, including secondary effects.
• knowledge of monitoring techniques, including knowledge of types of monitoring instrumentation, types of remote sensing, and methods of interpreting results for meaningful data.
• knowledge of how to use field- and desktop-derived information to calibrate numerical models and to simulate hazard events for risk assessment purposes.

Skills

The student can

• use rock-slope failure theory to assess, classify, and characterise an unstable slope by desktop methods and in the field.
• work in groups to collect structural data in the field using correct engineering geology mapping techniques.
• identify situations where drone technology is required for assessment, and use collected drone data to produce a point cloud and 3D site model.
• process structural data collected in the field, or from drone/LiDAR photogrammetry, using Pix4D, Coltop3D and kinematic software, e.g. Dips.
• process field mapping data and satellite/aerial images using GIS methods to produce meaningful information.
• interpret results from unstable slope monitoring campaigns to determine triggers/driving mechanisms for rock slope failure and make hazard predictions.
• use three-dimensional rockfall modelling software for rockfall hazard characterisation and risk assessment.
• determine the best solution for monitoring and managing the risk posed to society by unstable rock slopes.

General competences

The student can

• carry out the most important elements of geological research projects related to rock-slope failures: penetrating literature, carrying out basic field research, analyzing data, and communicating results to fellow students/scientists.
• work with landslide problems in the public and private sector using reflections, critical thinking and responsibility.
• solve problems related to rock-slope failures analytically and prompt in written English, and present research results orally.
• work independently and in a team.
