Modeling the effect of rockfall on forest development in a dynamic forest landscape model
disturbance dynamic forest modeling meta-model protection forest rockfall rockfall-forest feedback TreeMig
2023/11/20
Mountain forests below rocky cliffs are regularly impacted by falling blocks. Rockfall thus increases tree mortality and can locally alter the forest structure. At the same time, trees can decelerate ...
COMPARISON OF UAV-ENABLED PHOTOGRAMMETRY-BASED 3D POINT CLOUDS AND INTERPOLATED DSMs OF SLOPING TERRAIN FOR ROCKFALL HAZARD ANALYSIS
Drones UAV Photogrammetry 3D point clouds Rockfall Structure-from-Motion DSM
2016/10/14
UAVs are expected to be particularly valuable to define topography for natural slopes that may be prone to geological hazards, such as landslides or rockfalls. UAV-enabled imagery and aerial mapping c...
Numerical Simulations of Rockfall Protection Retaining Wall Joined to Steel-Pile Foundation
Impact Response Analysis Pile Foundation Rockfall Retaining-Wall
2011/12/20
In Japan, many rockfall protection walls have been constructed along the nationalhighways in mountainous areas. Up till now, usually these were gravity-type walls. However, ifthere is not much space b...
Rockfall vulnerability assessment for reinforced concrete buildings
Rockfall vulnerability reinforced concrete buildings
2010/10/21
The vulnerability of buildings to the impact of rockfalls is a topic that has recently attracted increasing attention in the scientific literature. The quantification of the vulnerability, when based ...
Rockfall-induced impact force causing a debris flow on a volcanoclastic soil slope: a case study in southern Italy
Rockfall-induced debris flow on a volcanoclastic soil slope southern Italy
2010/10/21
On 10 January 2003, a rockfall of approximately 10 m3 affected a cliff some 25 m high located along the northern slopes of Mt. St. Angelo (Nocera Inferiore, province of Salerno) in the southern Italia...
Experimental study of the impact response of geocells as components of rockfall protection embankments
Experimental study impact response geocells rockfall protection embankments
2009/12/16
Rockfall protection embankments are ground levees designed to stop falling boulders. This paper investigates the behaviour of geocells to be used as components of these structures. Geocells, or cellul...
Detection of millimetric deformation using a terrestrial laser scanner:experiment and application to a rockfall event
millimetric deformation terrestrial laser scanner rockfall event
2009/12/16
Terrestrial laser scanning (TLS) is one of the most promising surveying techniques for rockslope characterization and monitoring. Landslide and rockfall movements can be detected by means of compariso...
Parametric evaluation of 3D dispersion of rockfall trajectories
Parametric evaluation 3D dispersion rockfall trajectories
2009/12/14
The capability of evaluating and managing rockfall related risks is largely based on numerical modelling. Nevertheless, the reliability and accuracy of rockfall models is greatly affected by the stron...
Rockfall travel distance analysis by using empirical models (Solà d'Andorra la Vella, Central Pyrenees)
Rockfall travel distance analysis empirical models
2009/12/31
In total, data from twenty small rockfalls have been gathered which reveal an amount of a hundred individual fallen rock blocks. The data acquired has been used to check the reliability of the main em...
Rockfall hazard mapping along a mountainous road in Switzerland using a GIS-based parameter rating approach
Rockfall hazard mapping a mountainous road Switzerland a GIS-based parameter rating approach
2009/12/10
A posteriori studies of rock slope instabilities generally show that rockfalls do not occur at random locations: the failure zone can be classified as sensitive from geomorphological evidence. Zones s...
A methodology for physically based rockfall hazard assessment
physically rockfall hazard assessment
2009/12/10
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 defini...

Half-scale experimental study rockfall impacts sandy slopes
2009/12/10
In the framework of rockfall trajectory modelling, the bouncing phenomenon occurring when a rock block impacts with the slope surface is the most difficult to predict, owing to its complexity and its ...
Basic rockfall simulation with consideration of vegetation and application to protection measure
Basic rockfall simulation consideration vegetation application protection measure
2009/12/10
The estimation of risk due to rockfall is often done empirically. As a rational and effective method towards performance-based design of protection measures, a three-dimensional simulation method help...
