Título del libro: From Fundamentals To Applications In Geotechnics Título del capítulo: Fast moving landslides simulation by cellular automata
Landslides; Debris flow; Cellular Automata; Dynamic systems simulations
Resumen:
Cellular Automata CA are discrete computational models for simulating
dynamic systems that evolve on the basis on local interactions. Some
natural events, such as some types of landslides, fall into this type of
phenomena and lend themselves well to be simulated with this approach.
This paper describes a Cellular Automata model based on the equivalent
fluid approach, specifically developed to simulate debris-flows type
landslides. The methodology to approximately describe and model the main
features of a debris flow, is developed for overcoming some of the
limitation affecting conventional frames. The presented CA model for
debris flow is based on the principle of the equivalent fluid, stating
that: ``the flowing mass behaves like a fluid, whose rheological
features cannot be measured through laboratory or in situ testing, but
can only be obtained by the back-analysis of real past events''. A
general description of the adopted approach will be given in this paper,
together with the results of their application to real cases.
