On the computation of parameters that model snow avalanche motion
Bakkehøi, Steinar; Cheng, T.; Domaas, Ulrik; Lied, K.; Perla, R.; Schieldrop, B. (Journal article, 1981)This paper explores the computational problem of finding suitable numbers to use in a twoparameter model of snow avalanche dynamics. The two parameters are friction, y, and a ratio of avalanche mass to drag, MID. Given a ... -
Particle simulation of snow avalanche motion
Perla, R.; Lied, Karstein; Kristensen, Krister (Journal article, 1984)The continuum model of a snow avalanche is abandoned, and instead an avalanche is modeled as a collection of particles that move randomly and independently subject to gravity and resistive forces which have a random ...
