The 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 obtain reliable results using a dynamic analysis model is highlighted. .

Abstract
The 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 obtain reliable results using a dynamic analysis model is highlighted. .I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
