  Schematic representation of the four basic strategies to reduce lahar-hazard risk within lahar hazard zones. Strategies include (1) hazard avoidance with land-use planning and zonation; (2) hazard modification with engineered protection structures (bypass channel and deflection berm); (3) hazard warning to allow for timely evacuation; and (4) hazard response and recovery, which minimize long Simulation tools for gravitational mass flows (e.g., avalanches, debris flows) are commonly used for research and applications in hazard assessment or mitigation planning. As a basis for a transparent and reproducible decision making process, associated uncertainties need to be identified in order to quantify and eventually communicate the associated variabilities of the ://

where p 0 is the amplitude of the avalanche pressure given by the density of the powder cloud ρ, the form drag coefficient of the tree c d and the maximum velocity of the blast U max (Bozhinskiy and Losev, ; Feistl et al., a).The tree area over which the blast acts is denoted A, typically given by the tree height H and effective tree width :// Two-dimensional avalanche simulation software operating in three-dimensional terrain is widely used for hazard zoning and engineering to predict runout distances and impact pressures of snow

  Observational studies and back calculating of avalanches with a physical based avalanche model show that snow detrainment depends mainly on forest structural characteristics (basal area, species composition, terrain roughness) and the cohesive properties of snow (Feistl et Avalanches are the primary hazard for winter backcountry recreationists and cause numerous deaths and injuries annually. Although recreationists usually travel in groups, there is little empirical knowledge on group-related risk factors. This study aims to explore the relative risk of avalanche accidents with respect to group size and to discuss underlying reasons for different risk ://(15)/fulltext.
