Calculation of Avalanche Flow Velocity and Its Run-out Distance by the Using Mathematical Modeling and Residual Stress

In this paper, calculation of velocity, maximum velocity, dynamic pressure of avalanche release and run-out zone distance with considering residual stress are studied. To investigate of mathematical model, we have been taken gravitational, turbulent and friction forces and residual stresses. The main findings of the study are avalanche release velocity, dynamic pressure in three zones (starting zone, track zone and run-out zone), maximum velocity of avalanche in track zone and estimating run-out avalanche distance.
