ABSTRACT: Rockfall is a geological process that poses risks to the safe operation of transportation infrastructure in mountainous environments worldwide. The work presented here builds on work by Ondercin et al. (2016) demonstrating the applicability of 3D video game engines for the development of realistic rockfall simulations. Further development of the model is being completed with an emphasis on calibration using data from sites in British Columbia, Colorado and New Zealand. Each dataset provides information collected using a variety of remote sensing techniques, including terrestrial and aerial LiDAR as well as oblique aerial photogrammetry. The research reported here explores the ability of the game engine based modelling technique to simulate rockfall under the variable surface conditions present at each of the sites. This includes steep natural rock slopes, with debris-talus cover, as well shallower slopes with soil cover and vegetation. A comparison of the setup, model inputs and methods implemented in the model for each case study is presented.

RÉSUMÉ: de roche pose risques aux sécurités des opérations dans les régions montagneuses au tour du monde. Le travail ici présenté est basé sur le travail de Ondercin et al. (2016) Le développement du model continue en accordant une importance particulière à en utilisant les données reçues de la Colombie Britannique, Colorado et de la Nouvelle-parvenue de LiDAR terrestre et aérien ainsi que la photogrammétrie aérienne oblique, parmi une variété de technique de télédétection. La recherche présentée si dessous, démontre la capacité de modélisation à base de moteur de jeu pour naturelles
