Some numerical methods were applied to PCM snow avalanche model for
calculation of avalanche dynamics and the software named NUM-PCM 1.0 was developed.
The implemented numerical methods included Euler (1st and 2nd order Taylor
Polynomial), Midpoint, Modified Euler, and Runge-Kutta Order Four method. Once results
from numerical calculation were obtained, every approach was compared using
NUM-PCM 1.0, Also, friction parameter, mass-to-drag parameter, and delta
(horizontal distance) parameter of the model were tested with different
scenarios. It was found that run-out distance decreased when the other
parameters were constant with increasing of friction value. While mass-to-drag
was increasing, velocity of the avalanche was also increasing, although the
run-out distances were close to each other. In addition, it was determined that
when the horizontal distance exceeds 50 meters, even if the velocity values of
avalanche are close in each method, avalanche
with
high velocity
is stopped harshly without reaching the run-out zone.
