Resumen:
Frank avalanche, which took place in Canada in 1903, is analyzed to understand themechanisms involved in the processes of propagation using of advanced simulation tools allows toestimate the landslide propagation path, its velocity and the height of the deposits. The scope of thepresent approach focuses in the influence of the rheological and fragmentation laws in the evolutionof the avalanche. The main contribution of the paper is (i) the development of a rheological modelcoupled with a fragmentation model, and (ii) its application to a real avalanche.We have made a study of sensitivity for different models and rheological parameters, which hashelped us to optimize the approximation.
