L'objectif principal de ce travail de thèse est d'améliorer la prise en compte des peuplements de taillis dans les logiciels d'analyse trajectographique.Dans un premier temps, un modèle numérique permettant de créer des peuplements virtuels de taillis à l'échelle du versant a été développé et validé sur la base d'inventaires forestiers réalisés dans des taillis.Deux modèles numériques permettant de simuler des impacts de blocs sur des franc pieds et des cépées ont été également développés en utilisant la Méthode des Éléments Discrets (MED).Ces modèles ont été calibrés par des essais d'impact sur des tiges de hêtre.Ils permettent d'intégrer l'influence du houppier et du système racinaire, de modéliser explicitement le contact entre le bloc e...
