Back analysis of Johnsons landing 2012 landslide using two dynamic analysis models
DOIAbstract
none5siThe Johnsons Landing landslide occurred on July 12th 2012 in the mid-morning along Gar Creek, that flows from the Kootenay Joe Ridge to the Kootenay Lake, in the south-eastern British Columbia (Canada); it consisted of a debris avalanche with a volume of 300,000 m3. The event caused extensive damage in the area and killed four people. The aim of this work is to summarize the back-analysis of this event with the two dimensional computer-based model DAN-W and the three dimensional model DAN3D. The results constitute a step in the calibration procedure of the DAN-W and DAN3D models, that represent powerful tools in the frame of landslide risk management. Additionally, the issue of the level of topography smoothing which is necessary to ...
