Publishing papers presented at the Sixth International Conference on Computer Simulation in Risk Analysis and Hazard Mitigation, this book covers a series of important topics that are of current research interest and have practical applications. This proceeding is concerned with all aspects of risk analysis and hazard mitigation, ranging from specific assessment of risk to mitigation associated with both natural and anthropogenic hazards.The analysis and management of risk and the mitigation of hazards is of fundamental importance to planners and researchers around the world. We live in an increasingly complex society with the potential for disasters on a worldwide scale. The advances in computational methods, and the ability to model systems more precisely, now enable scientists and engineers to quantify hazards, simulate their effects and pursue risk analysis with greater accuracy. These developments not only are important for all areas of human endeavor but also have particular relevance to environmental issues where the risks involved are increasingly seen as substantial.This book encompasses a wide range of topics such as: geomorphic risk; risk perception, uncertainty and risk/multi-risk/vulnerability; transportations safety; urban risk and terrorism; climate change risks; network systems; safe ship operations; early warning systems; food safety; security risk; soil, water and air contamination; risk management; hazard prevention, management and control; estimation of risk.
