Development and Calibration of a Preliminary Cellular Automata Model for Snow Avalanches

Numerical modelling is a major challenge in the prevention of risks related to the occurrence of catastrophic phenomena. A Cellular Automata methodology was developed for modelling large scale (extended for kilometres) dangerous surface flows of different nature such as lava flows, pyroclastic flows, debris flows, rock avalanches, etc. This paper presents VALANCA, a first version of a Cellular ...

Snow Avalanches, Ice Avalanches and Glacier Surges

Mechanics of snow avalanches

The main problems of mechanics of snow avalanches are those of: (1) predicting avalanches, (2) avalanche motion, (3) the action of an avalanche upon obstacles, (4) the air wave, (5) the slow moving snow cover and its interaction with protective constructions and (6) the problem of artificial release of avalanches. This paper surveys the modern state of scientific knowledge about the nature of p...

developing a cellular automata model for urban growth

in the last decade, cellular automata models have been widely used for simulation spatial phenomena; however, exact nature of these models have been lead to various limitations for essential simulation of these phenomena. in this research, traditional cellular automata models have been developed through fuzzy theory, in which, transition rules are expressed based on fuzzy logic control methodol...
