The Research Center of Engineering Geology of the Institute for Geotechnics of Vienna University of Technology is organising the 6th Colloquium "Rock Mechanics - Theory and Practice" on the 22nd and 23rd March 2012 in Vienna, Austria.

Rockyfor3D has almost completely been translated into C (~2500 code lines). The first tests show that we can expect a significant increase of the computational speed (at least 30 times faster compared to the old matlab code which is cracking - british slang for quick), which is joyful news. We expect being able to deliver the bèta version of the C based Rockyfor3D version to all members in december 2011

We would like to focus your attention at a new book on rockfall entitled "Rockfall engineering" published by ISTE/John Wiley & Sons. This is an up-to-date, international picture of the state of the art in rockfall engineering.

he three basic stages of rockfalls are considered: the triggering stage, the motion stage, and the interaction with a structure stage; along with contributions including structural characterization of cliffs, remote monitoring, stability analysis, boulder propagation, design of protection structures an risk assessment. Academic contributions are illustrated by practical examples, and completed by engineering contributions where practical purposes are thoroughly considered.

This title is intended for engineers, students as well as researchers. The chapter on rockfall trajectory modelling is written by ecorisQ members.

By courtesy of one of our members, Guillaume Favre-Bulle, working at GeoVal in Sion (CH), three SAGA GIS batch files, which automatically create the raster sets needed for Rockyfor3D can be downloaded here. Working with these batch files saves a lot of time for data preparation. A quick guide on data preparation for Rockyfor3D can be downloaded here.

Here is a relatively stable film showing rebound heights and distances, as well as the stochastic nature, of falling rocks in the Grand Couloir on the Mont Blanc. It shows very well that on steep bedrock/talus slopes, rebounds can be impressivily high and long (> 40 m height).
