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

SNOWPACK

• 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
