Book Description
NUMGE 2018 is the ninth in a series of conferences on Numerical Methods in Geotechnical Engineering organized by the ERTC7 under the auspices of the International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE). The first conference was held in 1986 in Stuttgart, Germany and the series continued every four years (1990 Santander, Spain; 1994 Manchester, United Kingdom; 1998 Udine, Italy; 2002 Paris, France; 2006 Graz, Austria; 2010 Trondheim, Norway; 2014 Delft, The Netherlands). The conference provides a forum for exchange of ideas and discussion on topics related to numerical modelling in geotechnical engineering. Both senior and young researchers, as well as scientists and engineers from Europe and overseas, are invited to attend this conference to share and exchange their knowledge and experiences. This work is the first volume of NUMGE 2018.

Book Description
"Rock clusters falling down an inclined slope is a problem of growing concern in mountainous regions and poses a significant risk to people, roads, and other infrastructure. Different aspects of the problem have been previously investigated using physical modelling and numerical analysis. However, three dimensional impact force distribution on a barrier wall resulting from rockfall over a rough slope is scarce in the literature. In this study, a series of experiments are conducted to track the movement of granular particles down a slope and measure the impact force imposed by the falling rock clusters on a nearby vertical wall. The rock blocks are released from a container located at the top of the slope and the velocity profiles are recorded using marked pebbles and a high-speed camera. The effect of the rockfall volume, slope angle, and distance to the wall on the velocity profiles and impact forces are investigated. Validated using the experimental results, discrete element simulations are performed using PFC3D to evaluate the effect of particle sizes on the flow characteristics and final impact pressure on the structure. Analysis showed that impact energy is highly affected by the slope inclination, the shape of rock clusters, and runout distance. The research results have been submitted in refereed journals and have been published in conference proceeding amounting to 2 journal papers and 1 conference paper. These papers are compiled to produce 5 chapters in this manuscript-based thesis. The investigation of the effects of sphericity and angularity of particles on the dynamics of rockfall is first conducted using three dimensional distinct element method (DEM) to illustrate the importance of the consideration of sphericity and particle shape in modelling rockfall problems involving movement pattern and impact forces on the rigid barrier structure imposed by the falling rock clusters. The rest of the thesis is devoted to comprehensively analyze the influence of the irregular-shaped particles on the dynamics behavior of rockfall and impact forces exerted on the rigid structure in discrete element method. Replication of the experimental system, the calibration procedure needed to determine the propertiesof the discrete elements is necessary for a reasonable numerical simulation (e.g. restitution coefficient, internal friction angle). By adopting a suitable damping ratio and friction coefficient among the contacts for each distinct element, the numerical accuracy of the falling rock clusters has been maintained. Conclusions and recommendations are made regarding the slope inclination, volume effect on the impact imposed by falling rock clusters on rigid structure." --

Book Description
Landslide Hazards, Risks and Disasters Second Edition makes a broad but detailed examination of major aspects of mass movements and their consequences, and provides knowledge to form the basis for more complete and accurate monitoring, prediction, preparedness and reduction of the impacts of landslides on society. The frequency and intensity of landslide hazards and disasters has consistently increased over the past century, and this trend will continue as society increasingly utilises steep landscapes. Landslides and related phenomena can be triggered by other hazard and disaster processes – such as earthquakes, tsunamis, volcanic eruptions and wildfires – and they can also cause other hazards and disasters, making them a complex multi-disciplinary challenge. This new edition of Landslide Hazards, Risks and Disasters is updated and includes new chapters, covering additional topics including rockfalls, landslide interactions and impacts and geomorphic perspectives. Knowledge, understanding and the ability to model landslide processes are becoming increasingly important challenges for society extends its occupation of increasingly hilly and mountainous terrain, making this book a key resource for educators, researchers and disaster managers in geophysics, geology and environmental science. Provides an interdisciplinary perspective on the geological, seismological, physical, environmental and social impacts of landslides Presents the latest research on causality, impacts and landslide preparedness and mitigation. Includes numerous tables, maps, diagrams, illustrations, photographs and video captures of hazardous processes Discusses steps for planning for and responding to landslide hazards, risks and disasters
