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.
