This dissertation contributes to the improvement of the predictive accuracy of the impact capacity of rockfall protection galleries and to the establishment of a performance-based design procedure for these structures. Furthermore, it facilitates the understanding ...

<p>This report outlines detailed 3D rockfall modelling of multiple areas within the Canterbury Port Hills near Christchurch, New Zealand. It includes a rockfall hazard assessment for the area. This analysis will provide Canterbury Earthquake Recovery Authority ...

Rockfall is an extremely rapid process involving long travel distances. Due to these features, when an event occurs, the ability to take evasive action is practically zero and, thus, the risk of injury or loss of life is high. Damage to buildings and infrastructure ...

Rockfall propagation areas can be determined using a simple geometric rule known as shadow angle or energy line method based on a simple Coulomb frictional model implemented in the CONEFALL computer program. Runout zones are estimated from a digital terrain ...

An important issue in the evaluation of potential hazard related to rockfalls is the quantitative prediction of the traveling distance of the falling blocks, which is necessary to identify the potentially endangered area. This information is also fundamental ...

The highway between Aswan and Cairo on the eastern bank of the Nile Valley is one of the most used highways in Egypt, connecting most of the governorates with each other. It represents the backbone of Egyptian transportation and commercial traffic. This Highway ...

The accuracy of rockfall trajectory simulations depends to a large extent on the calculation of the rebound of falling boulders on different parts of a slope where rockfalls could occur. The models commonly used for rebound calculation are based on restitution ...

We used one of the few rockfall models explicitly taking trees into account and compared the results obtained with the 3D simulation model RockyFor with empirical data on tree impacts at three mountain forests in Switzerland. Even though we used model input ...

Anglo Coal South Africa mines coal for both the domestic and export market using open cast and strip mining methods. To establish a mine, a process is set in place to gather ever increasing amounts of geological and metallurgical data to confirm a proven reserve. ...

The Strug landslide was triggered in December 2001 as a rockslide, followed by a rock fall. In 2002, about 20 debris flows were registered in the Kose˘c village; they were initiated in the Strug rock fall source area. They all flowed through the aligned Brusnik ...
