<p>The impact force of a rockfall is mainly determined by its moving behavior and velocity, which are contingent on the rock shape, slope gradient, height, and surface roughness of the moving path. It is essential to precisely calculate the moving path of ...

In this paper, a general formulation using a Taylor series expansion is proposed for the quantification of the relative importance of the different processes that explain the variability of the reflected velocity vector after bouncing.

The objective of this work is to develop elements to improve understanding of the behavior of a coppice in relation to the phenomenon of falling boulders.

Rockfall protection embankments are ground levees designed to stop falling boulders. This paper investigates the behavior of geocells to be used as components of these structures.

After a summary of the main conclusions drawn from a small-scale study, the paper focuses on half-scale experiments, describing first the testing device and the data processing and analysing then the influence of several impact parameters in order to study ...

In this experimental study, natural rock pieces as well as concrete balls and cubes having imbedded accelerometers in them were made to fall and roll over a 45m high natural slope composed of exposed rocks and vertical planes in an attempt to elucidate further ...

Models can be useful tools to assess the risk posed by rockfall throughout relatively large mountainous areas (&gt;500 km2), in order to improve protection of endangered residential areas and infrastructure. Therefore the purpose of this study was to summarize ...
