En montagne, la forêt est une barrière de protection efficace contre les risques naturels comme les chutes de pierres et de rochers qui compromettent la sécurité des biens et des personnes. Il reste toutefois encore difficile d'en définir les mécanismes et de quantifier cette capacité de protection. Les gestionnaires forestiers trouveront dans cet article la présentation d'un outil permettant, grâce à la définition de plusieurs paramètres locaux, une évaluation quantitative rapide de la capacité de protection de la forêt contre les chutes de pierres à l’échelle d’un versant.There are presently no clear rules for determining the optimal rockfall protection forests, taking into account forest and site characteristics, as well as the size and energy of the falling rock. To provide a tool that meets this requirements and that quantifies the protective capacity, we developed Rockfor.NET (www.rockfor.net). This paper explains the underlying principles as well as the calculation methods used. Further it presents case studies that served for validation.
