Dynamic modelling with DAN3D of Stampa scenario 3A

The unstable rock slope at Stampa (Aurland Municipality; Sogn og Fjordane), is among the largest unstable rock slopes in Norway. It has been investigated over more than a decade in detail and several scenarios have been defined for potential failure. One of those (scenario 3A, also called Joasetbergi) has recently been defined as a high risk site that requires continuous early warning. The main goal of the work outlined in this report was to model the run-out dynamics of a potential failure of this high risk scenario. The dynamic modelling was carried out with the software DAN3D, that is widely used to model the motion of highly mobile landslides. The results obtained with the DAN3D software were compared to the Flow-R run-out model, which is the software used by NGU for all unstable rock slope in Norway. We have defined 39 plausible propagation models by selecting a wide range of plausible input parameters.
