  Model development
  • Using the data from the experiments (Objective 2), the three main shortcomings of presently used models will be addressed, namely (i) the lack of realistic rheological laws, (ii) the absence of snow entrainment in the modelling, and (iii) the heuristic description of the formation of a layer of suspended particles (the powder snow 'cloud').
  • Mathematical expressions will be sought for the internal stresses, the entrainment and the suspension rates that capture the essential physics of the phenomena and depend on local flow variables (e.g., the shear rate and the flow depth) and the measurable material parameters of the snow (density, shear strength, cohesion).
  • A meeting to discuss the best way to progress with these developments was held in Leeds, UK from the 17-19 January, 2003. Please follow the link below for more information about the conclusions of this meeting.
  • A meeting to discuss progress and further issues and methodologies was held in Tyriheim, Norway from the 19-21 April, 2004. Please follow the link below for more information about this meeting and to download the presentations.
