Key issues in 3D rockfall modeling, natural hazard and risk assessment for rockfall protection in Hřensko (Czechia)

Popis výsledku v původním jazyce

The growing urban development in mountain areas together with climate change increased the need for rockfall research and modeling. Determining rockfall processes and related hazard isnstill a difficult task because of the complexity and intrinsic stochastic nature of the physics involved. In recent years, numerical simulations of rockfall trajectories became commonnprocedure for evaluating rockfall hazard. Increasing of model accuracy leads to the need for more specific complex calibration, appropriate combination of rockfall modeling tools, as wellnas careful assessment of rockfall sources, block and slope characteristics. Rockfall modeling issues have been tested in local study areas in Hřensko (Czechia) through HY-STONE 3Dnsoftware. The Hřensko area is characterised by sandstone landscape with rock plateaus, deep canyons with several levels of steep cliffs, which forms favourable conditions for rockfalls.nDifferent modeling approaches, calibration problems, dependency of model results to parameters, and proposed appropriate countermeasures are discussed. The aim of this paper is tonprovide a knowledge base for researchers and practitioners involved in projects dealing with rockfall protection.
