Towards objective rockfall trajectory modelling using a stochastic rebound algorithm

A challenge in rockfall modelling is to develop a robust rebound algorithm for which parame-ter values can be estimated objectively in the field. In this paper, we tackle this challenge by presenting and testing a stochastic impact law that requires limited parameterisation by the model user. The approach provides promising results. We will present the simulation results and their validation as well as remaining unknowns and future developments.
