Snow Transport and Deposition

This lecture covers the mechanisms of snow transport, including saltation and suspension, as well as the forces acting on snow grains. It discusses the threshold wind speed for saltation, the drift index for avalanche warning, and the comparison of different snow transport models. The lecture also explores the concept of an Integrated Measurement and Information System (IMIS) Automatic Weather Station (AWS) and the modelling of snow deposition using Lagrangian Stochastic Models. It delves into the formulation of suspension in the Alpine3D model system and presents a new paradigm of snow accumulation. The lecture concludes with simulations and measurements at specific mountain locations to study snow distribution and topographical flow features.
