“…PICUS v1.41 is a modular forest modelling framework centred around a hybrid patch model which incorporates a number of flexible sub-models for scenario analysis (e.g., forest management, bark beetle damage, rockfall protection; Seidl et al 2005;Seidl et al 2007a;Woltjer et al 2008). Here, besides a brief overview of the general model logic the bark beetle disturbance sub-model will be described in more detail.…”

“…Recently Woltjer et al (2008) developed a spatially explicit 3-D rockfall model and coupled it with the process oriented 3-D forest patch model PICUS v1.4 (Lexer and Hönninger, 2001;Seidl et al, 2005). In Woltjer et al (2008) the new rockfall model was tested for parameter sensitivity and for its ability to assess rockfall protection effects in line with static formulations from the literature (Gsteiger, 1993;Brauner et al, 2005).…”

Abstract. Many slopes in the Alps are prone to rockfall and forests play a vital role in protecting objects such as (rail) roads and infrastructure against rockfall. Decision support tools are required to assess rockfall processes and to quantify the rockfall protection effect of forest stands. This paper presents results of an iterative sequence of tests and improvements of a coupled rockfall and forest dynamics model with focus on the rockfall module. As evaluation data a real-size rockfall experiment in the French Alps and two 2-D rockfall trajectories from Austria and Switzerland were used. Modification of the rebound algorithm and the inclusion of an algorithm accounting for the sudden halt of falling rocks due to surface roughness greatly improved the correspondence between simulated and observed key rockfall variables like run-out distances, rebound heights and jump lengths for the real-size rockfall experiment. Moreover, the observed jump lengths and run-out distances of the 2-D trajectories were well within the stochastic range of variation yielded by the simulations. Based on evaluation results it is concluded that the rockfall model can be employed to assess the protective effect of forest vegetation.
