GUI RF3D v521Improvements in the Graphical User Interface (GUI) of the 3D rockfall trajectory simulation software Rockyfor3D have been implemented on demand of the many users. The current version (Rockyfor3D v5.2.1) allows a “rapid automatic simulation”, which only requires a Digital Elevation Model as input. All parameters related to surface roughness and elasticity are calculated automatically, using pessimistic values. The new GUI also allows defining directly the form and the dimensions of the blocks to be simulated. Errors related to directory paths containing spaces have been fixed. The algorithms for calculating the rockfall kinematics have not been changed. All members can download Rockyfor3D v5.2.1 from the tools section of our website (after login).

 

 

We proudly present our new software for detecting trees in high resolution surface data, called FINT (Find INdividual Trees). The software is freely downloadable for all members from the tools section of our website. The tool FINT extracts positions of dominant and co-dominant trees from high resolution surface models (e.g., from LiDAR data) of forests. Since most users have access to raster data used in standard Geographical Information Systems (GIS) instead of 3D point data, FINT is based on the identification of local maxima in raster data. The principal aim of FINT is to obtain a realistic forest structure in the sense that the positions of the largest trees and the locations of the main gaps and couloirs in the forests are recorded and subsequently integrated in natural hazard process simulation models. FINT can be too imprecise for silvicultural analyses (e.g, estimation of stand density, basal area and standing volume), especially for broadleaved and mixed forests. An important variable determining the precision of the outcomes is the resolution of the input data. Therefore, a minimal resolution of 1 x 1 m is recommended. More information can be found here.

After deveral days of continuous rainfall, three train wagons of the Rhätische Bahn have been derailed by a shallow landslide on 13 August 2014, in the canton of Grisons (Switzerland). Luckily, as was the case with the train the pignes in France, the most critical wagon was retained by trees downslope, instead of falling 60 meters down into the ravine. Nevertheless, the landslide caused 1 casualty and several injured persons. 

Conf Padua 2014

We would like to focus your attention on the International conference on "Analysis and Management of Changing Risks for Natural Hazards". It will take place on 18-19 November 2014 in Padua, Italy. The focus of the conference focus is on:

  • technical sessions presenting the state of the art research in the understanding of the natural processes and in the development of innovative methodologies for quantitative hazard and risk forecasts
  • practical integration of natural, engineering, economical and human sciences within multi-scale methodologies for risk management and prevention planning

The conference provides an opportunity to discuss multi-hazard risks and multi-disciplinary research results on the effects of changing of hydro-meteorological risks and their effects on planning strategies. Here you can find more information.

On February 8th, 2014, a direct impact of a rockfall on the touristic train de pignes in the southern part of France (Alpes-de-Haute-Provence, ) caused two casualties and one injured person. The two train wagons were derailed by the impact and subsequently retained by trees downslope. More information can be found here (in French).
