An empirical approach for determining the evolution and behavior of rockslide dams. - Development of a empirical tool based on geomorphic parameters of rockslide dams and impounded valleys to predict future rockslide dam heights and their relative longevity
Jakobsen, Vegard Utstøl (Master thesis, 2016)The secondary consequences of rock slope failure poses a threat to people living in Norwegian valleys. Blockage of rivers cause flooding upriver. Catastrophic breaching of the dam poses as major threat to people living ... -
Back-analysis of the 1756 Tjellefonna rockslide, Langfjorden
Sandøy, Gro (Master thesis, 2012)The 22nd of February 1756 the largest historically recorded rockslide in Norway took place at Tjelle in Langfjorden, Møre & Romsdal County. Three displacement waves of up to 50 meters were created in Langfjorden by the ... -
Engineering geological assessment and structural comparison of the Vollan and Ivasnasen rock slopes at Sunndal, Norway
Dreiås, Gudrun Majala (Master thesis, 2012)This master thesis has interest in analyzing the two unstable rock slopes Ivasnasen and Vollan. These rock slopes are located in a U-shaped valley in Sunndal municipally (Møre & Romsdal, western Norway). The analyses are ... -
Entrainment potential of rock avalanches in Norway. - Parameter test and case study at the unstable rock slope Børa (Romsdal Valley, western Norway)
Andresen, Martine Lund (Master thesis, 2017)Rock avalanches are frequently reported to entrain significant volumes of debris on their travel path. However, little is known about the debris entrainment potential in Norway. This thesis aims to evaluate and better ... -
Gravitational reactivation of a pre-existing post-Caledonian fault system: the deep-seated gravitational slope deformation at Middagstinden, western Norway
Schleier, Markus; Hermanns, Reginald Leonhard Manfred; Krieger, Ingvar; Oppikofer, Thierry; Eiken, Trond; Rønning, Jan Steinar; Rohn, Joachim (Journal article; Peer reviewed, 2016)The origin of linear features in mountain terrain that form distinct vertical steps is generally not obvious and has been discussed to be related to either tectonic faulting or gravitational slope deformation. A strong ... -
Semi-empirical prediction of dam height and stability of dams formed by rock slope failures in Norway
Oppikofer, Thierry; Hermanns, Reginald; Jakobsen, Vegard Utstøl; Böhme, Martina; Nicolet, Pierrick; Penna, Ivanna (Peer reviewed; Journal article, 2020)Based on an inventory of 69 dams formed by rock slope failures in southwestern Norway and published inventories from other parts of the world, we developed semi-empirical relationships linking the maximum dam height (HD.max ... -
Subaqueous rock-avalanche deposits exposed by post-glacial isostatic rebound, Innfjorddalen, Western Norway
Schleier, Markus; Hermanns, Reginald Leonhard Manfred; Gosse, John C; Oppikofer, Thierry; Rohn, Joachim; Tønnesen, Jan Fredrik (Journal article; Peer reviewed, 2016)This paper presents a detailed description of deposits and landforms of multiple rock avalanches in Western Norway, one of which fell onto water-saturated sediments in Innfjorddalen below the former water level. Deposits ...
