Rockfall-Simulation FWP Penken

It is the aim of the study to adapt and further develop PICUS ROCKNROLL, a combined forest - ecosystem - rockfall simulation model, jointly developed by the Institute of Forestry, BOKU Vienna and the Institute of Alpine Risk Engineering, BOKU Vienna. On occasion of the ongoing study on renovation and future protection of rockfall protection forests in the Penken area, Zillertal, Tyrol, the model setup was adapted to the local situation, taking into account a DGM, the actual forest cover as well as rockfall activity and intensity. In a first step forest development was simulated for a period of 100 years, taking into account different management scenarios which were conceptualized together with the federal forest service. In a second step for each of these scenarios the effect of rockfall damage on forest development was simulated and suitable indicators assessing the shelter effect of each protection forest management scenario were developed. By applying cost-efficiency-analysis, an economic assessment of the different protection forest management scenarios was carried out.
