"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."

This thesis represents one of the few studies so far that systematically analyses environmental conditions within debris flow source areas to determine their relative importance for debris flow development. Environmental site conditions, such as slope gradient and debris availability, influence the spatial and temporal distribution of debris flows in high-alpine areas. However, current understanding of these preconditioning controls is mostly qualitative and inadequate for debris-flow hazard assessments and climate change impact studies. The author's research investigates the role of frost weathering and permafrost in the occurrence of debris flows in the Southern Alps of New Zealand. Analyses are based on an extensive debris flow inventory, documenting debris flow occurrence and activity over the last 60 years in selected catchments. Debris flow activity is compared to frost-weathering intensity estimates from two models, allowing the practical comparison of two competing frost-weathering hypotheses currently discussed in literature. Information on permafrost occurrence is based on a new distributed permafrost estimate for the Southern Alps, derived from climatic conditions at active rock glacier sites. This pioneering thesis provides empirical evidence that frost weathering promotes debris-flow formation. It further highlights the potential and limitations of regional-scale studies for advancing our understanding of debris-flow preconditioning factors.

This disaster risk financing country note for Serbia provides an overview of the way its government currently finances the costs imposed by natural disasters. Meanwhile, poverty deepened after the financial crisis and during the recessions of 2012 and 2014, mainly because of losses in employment and labor income. In an effort to overcome its fiscal challenges, the government of Serbia adopted an ambitious fiscal consolidation and structural reform program to halt the rise in public debt and send it on a downward trajectory by 2017. This program is supported by a three-year stand-by arrangement from the International Monetary Fund (IMF). Because of the growing frequency and severity of disasters, the government has faced the rising costs of responding to disasters as well as the challenges of financing emergency response and reconstruction costs. Having sufficient access to financial instruments and resources in order to respond to disasters is crucial for building the financial resilience of the country and minimizing the negative impact of natural disasters on Serbia's economic growth. In this report, chapter one gives introduction. Chapter two provides the background and country context, including the recent economic impacts of disasters. Chapter three reviews the current institutional and legal framework for disaster risk management and financing. Chapter four is a review of the public financial management of disasters in Serbia, including ex ante and ex post disaster risk financing and insurance (DRFI) instruments currently in use for budget mobilization, and it looks at the 2014 floods in more detail. The chapter concludes with a summary of financial resources available and a look at the potential resource gaps.
