Potentials and challenges of snow drift simulation for avalanche warning

INTERPRAEVENT 2012 - Proceedings
The current understanding of snow drift modelling is reviewed. To overcome the most critical modelling issues of the state of the art models a continuum approach for advanced snow drift modelling is presented. This includes time dependent boundary conditions (BCs) from Numerical Weather Prediction (NWP) models, turbulent air flow and changing topography of the snow cover. This model is used to investigate snow transport at the Planneralm test site (Styria, Austria). Parameter studies show that the driving wind field is the most sensitive modelling parameter. Finally, the model is validated by two years of measurements from weather stations at the Planneralm (Austria, Styria), where two characteristic snow drift events are discussed in detail.
