Book Description
Rockfall Engineering is an up-to-date, international picture of the state of the art in rockfall engineering. The 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.

Book Description
From out of the clear blue sky, an unknown chunk of rock from the frozen void strikes the Earth with unimaginable force, gouging a wound into the very crust of the planet. Millions die in an instant, and millions more await the end as the looming catastrophe unfolds...Thousands of miles away from the disaster, a call comes in the middle of the night. Families act, and react, and while panic spreads, the world keeps on spinning. Maybe a little slower, and perhaps with a teeny bit more of a tilt, but such things are a mere trifle to the existence of a planet. For the human inhabitants of this planet, though, the meteor's collision will have far-reaching effects as the impact creates ripples throughout their fragile existence.Bryan Hardin just wanted to create a sanctuary in the country for his remaining family, a place to heal his wounded spirit as he struggles with survivor's guilt and approaching middle age. He's hardly the heroic type, but his family is going to need all of them to act like heroes if they are going to survive the spreading effects of the Rockfall. The Earthquakes are Primary Effects.The Tsunami are Secondary Effects.Will Anybody Survive the Tertiary Effects?

Book Description
Mass movement of rocks in high mountains can severely injure the population and damage man-made structures in these areas. This book focuses on the understanding of the mechanisms of rockslides and rockfalls using a quantitative approach. The range and velocity of these hazards are calculated to serve as a basis for evacuations and other preventive measures. Examples from four continents illustrate the necessity of this kind of information. The book contains a wealth of information for practitioners and scientists working in the field of catastrophe prevention.

Book Description
This pioneering work deals with the parameterization of rockfalls in the context of 3D run-out modelling at a study site in the Bavarian Alps. The main objective was to cover not only low-magnitude, high-frequency rockfalls (10 msup3/sup) but also Mid-Magnitude events, which involve rock volumes of between 10 and 100 msup3/sup (boulder falls) and between 100 and 10,000 msup3/sup (block falls). As Mid-Magnitude events have been insufficiently covered in terms of rockfall modelling up to now, a geomechanical approach has been developed to characterize those events by means of a case study. For a 200 msup3/sup limestone block a potential failure scenario was analysed by combining a deterministic failure analysis with a numerical process-based run-out model. To model potential run-out scenarios of the 200 msup3/sup block, the beta version of the code RAMMS::Rockfall, developed by the Swiss Institute for Snow and Avalanche Research (SLF), was applied. RAMMS::Rockfall makes it possible to include the block shape and thus consider the effects of varying block shapes on the run-out distance. The run-out modelling for the entire project site was performed using the scientific code Rockyfor3D (Dorren/ecorisQ). To provide quantitative information in terms of input parameters, a field recording of block sizes at the talus slope, as well as a detailed discontinuity analysis at the source area, were conducted. The book successfully demonstrates how detailed and quantitative field investigation can contribute to 3D rockfall modelling./pp

Book Description
Gravity hazards are a major concern to those living in mountainous areas. To protect infrastructure and human life in these areas, engineers require numerical tools for trajectory analysis, for application from fragmental rockfalls to large-scale avalanches or landslides.This book explores state-of-the-art methods to model the propagation (flows and stops) of masses, using the discrete element method (DEM) to study the evolution of kinetics during an event. Taking into account the shape of the blocks and the topology of the terrain provides an explicit and sophisticated consideration of geometries, eliminating the need for stochastic inputs to rockfall simulations. This method is validated experimentally, before the authors apply it to real case studies. The book ends with an introduction to and comparison with the material point method (MPM), a new and promising approach able to bridge the gap between cases dominated by discreteness and those involving a very large number of elements.Engineering consulting firms, researchers and students should find the approaches outlined in this book useful, whether designing prevention and protection systems for gravity hazards, or exploring new ways to model gravity hazards. - Covers conventional methods used to study gravitational phenomena using empirical parameters - Presents a new numerical tool taking account of the physical phenomenon (friction, dissipation, realistic block shapes) and a methodology for parameter calibration and the achievement of numerical simulations - Applies the numerical model to real cases with a critical analysis of its applicability in the field of engineering - Emphasizes the discrete element method (DEM)
