Consultancies using rockfall simulation software, as well as rockfall software developers, have been invited to use their simulation tools to predict the trajectories of 100 rocks in 2D or 3D using a digital elevation model of a site in the French Alps. These ...

Only a few rockfall simulation models take into account the mitigating effect of existing forest cover. The objective of our study was to improve the generic rockfall simulation model RockyFor, which does take the effect of forest stands into account, thereby ...

Adequate management of a mountain forest that protects downslope areas against impacts of rockfall requires insight into the dynamics of the hillslope environment. Therefore, we applied a combined approach, using field and modelling techniques, to assess the ...

It is investigated whether a GIS-based distributed model developed for rockfall assessment at slope scale, which uses data with a support of 2.562.5 m, could be used for rockfall assessment at the regional scale, using input data with a support of 25625m and ...

The accuracy of model output increases with a decreasing support size of the input data, due to the increase of detail. This paper examines whether this is true for various spatial models developed for simulating rockfall. We analyze the effect of the support ...

This paper reports an analysis procedure for the evaluation of the features of the motion of blocks detaching from a steep rock wall and traveling down the slope below. Starting from the execution of real scale rock fall tests, carried out on two slopes having ...

Site-specific information about the level of protection that mountain forests provide is often not available for large regions. Information regarding rockfalls is especially scarce. The most efficient way to obtain information about rockfall activity and the ...

Rock slides and rock falls are the most frequent types of slope movements in Yosemite National Park, California. In historical time (1857–2002) 392 rock falls and rock slides have been documented in the valley, and some of them have been mapped in detail. ...

Rockfall hazard assessment is not simple to achieve in practice and sound, physically based assessment methodologies are still missing. The mobility of rockfalls implies a more difficult hazard definition with respect to other slope instabilities with minimal ...

Rockfall hazard assessment is a fundamental land planning tool in high mountain area. In this paper, a new rockfall hazard methodology is applied, based on the results of a 3D rockfall numerical model performed through an original simulation code. This ...
