Abstract: |
Numerical modelling of rockfall events is an increasingly significant basis for the production of hazard maps and the design of protection structures. The fact that the various programs on the market lead to different results in specific cases has led to discussion. The programs most commonly used in Switzerland are therefore compared with regard to input parameters and results, the main and auxiliary algorithms and further aspects. The difference between deterministic and probabilistic methods is important. The probabilistic method requires great caution and experience, both in the parameter input and in the interpretation of the results. This poses the general question, what uncertainties have to be dealt with in the management of natural hazards. |
