The calibration of an avalanche mathematical model using field data

Abstract: Abstract. The experience of calibrating Eglit's avalanche model using data about the avalanche travel distance lengths and velocity data from the Zailiyskiy Alatau range (Kazakhstan) is discussed. Empirical equations are proposed that describe the dependence of the friction coefficients on the avalanche volume and type.

“…Currently, each country concerned with the avalanche hazard has its own code based on this type of equations. Probably the most representative model is that developed by S. Savage and K. Hutter [18]. Nowadays, this set of equations is generally referred as the Savage–Hutter model.…”

“…Néanmoins, ces modèles souffrent tout autant que les modèles de déclenchement du manque de connaissances du manteau neigeux. Ils font donc appel à des lois au moins partiellement empiriques, notamment en termes de lien entre vitesse et pression et de loi de frottement dont les coefficients doivent être calibrés sur des événements réels (Buser et Frutiger, 1980 ;Martinelli et al, 1980 ;Blagovechshenskiy et al 2002).…”
