Snow & Avalanche Study Establishment (SASE), Chandigarh
Snow and Avalanche Study Establishment (SASE)• Established on 01 Oct 1969 at Manali.
Running through Golden Jubilee year.• Core Mission
• To develop technologies to mitigateavalanche hazard to men and its facilitiesin snow bound areas.
• Focus Areas
– Issue of avalanche and weatherforecast for snow bound regions.
– Development of technologies for• Avalanche Hazard mapping• Structural control of Avalanches• Artificial Triggering of Avalanches
– Providing consultancy for avalancheprotection to highways and otherinfrastructure in snow bound mountainregions
Snow Avalanche - Sudden downhill motion of snow mass.
Avalanche•Sudden downward motion of snow mass; may contain rocks, soil, ice trees etc•Exerts pressure up to 50 Tn/m2

Factors affecting Avalanche Formation§ Avalanche Hazard is dependent on 3 parameters:
1. Terrain2. Weather3. Snowpack
Avalanche Hazard

• Elevation• Slope• Aspect• Curvature
• Temperature• Humidity• Pressure• Wind• Radiation
• Snow Depth• Snow Surface

Challenges
Vast, rugged, snow-bound mountainous area.
Inhospitable weather, poor accessibility, limited working season.Health Hazrads
Human effort –excruciating, error prone, time consuming
Large variability –spatial & temporal distribution, frequent movement
