Özet
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.
