Evaluation of the effectiveness of the snow fences Burtschakopf-West
Abstract
Snow fences are used as permanent protection measures to accumulate snow in defined areas. However, the snow cover distribution in alpine terrain is known to be highly influenced by the local wind field. Therefore positioning and dimensioning of snow fences is -contrarily to flat terrain- a difficult matter. In this study a new methodology is used for this goal to evaluate the snow fences at the potential avalanche release zone “Burtschakopf-West”. The methodology contains amongst others: A) Three-dimensional wind field modelling using the atmospheric model ARPS (Advanced Regional Prediction System). B) Creation of snow height maps using terrestrial laser scanning technology and picture analyses. The computing of activity areas of potential snow fences is finally done using Tabler equation for classified snow drift events.
