Au regard du Code de l’environnement, les digues, considérées comme ouvrages hydrauliques, ne doivent pas rompre de façon dangereuse pour les populations. En tant que moyen de prévention du risque d’inondation ou de submersion, les performances et les limites de ces digues doivent être connues avec précision. Les digues de protection constituent donc une question politique mise en évidence par plusieurs événements récents (Xynthia 2010, la NouvelleOrléans 2005, Rhône aval 2003, Gard 2002, Aude 1999). Cet ouvrage rassemble les contributions présentées lors du 2e colloque national Digues maritimes et fluviales de protection contre les submersions (Digues2013), organisé par l’Irstea et Promosciences, les 12, 13 et 14 juin 2013 au Centre des Congrès d’AixenProvence, avec le soutien du MEDDE, du CFBR, et de la Région ProvenceAlpesCôte d’Azur. Il s’adresse aux maîtres d’ouvrages, gestionnaires, concepteurs, constructeurs, enseignants et chercheurs, services de contrôle, organismes financeurs, agissant dans les domaines d’activités liés, directement ou indirectement, à la sûreté des digues maritimes et fluviales.

Our societies have become very crisis-prone. This book explores crises and the methods of anticipation, management and reconstruction, and considers a risk-crisis-territorial development continuum. The aim is to better understand a widely used concept and clarify the methods of action in the field of crisis management. The different forms of learning proposed to better face future crises are also questioned. This book invites us to analyze the resources available to support crisis management and reconstruction, and consider the unequal access to these resources in different territories in order to design future territorial strategies. This often results in a form of territorial inertia after the crises. However, some innovate, imagine renewed territories, prepare for reconstruction, or even recompose territories now in order to make them more resilient. The crisis can then be the driving force or the accelerator of these changes and contribute to the emergence of new practices, or even new urban and territorial utopias.

This book gathers a collection of extended papers based on presentations given during the SimHydro 2017 conference, held in Sophia Antipolis, Nice, France on June 14–16, 2017. It focuses on how to choose the right model in applied hydraulics and considers various aspects, including the modeling and simulation of fast hydraulic transients, 3D modeling, uncertainties and multiphase flows. The book explores both limitations and performance of current models and presents the latest developments in new numerical schemes, high-performance computing, multiphysics and multiscale methods, and better interaction with field or scale model data. It gathers the lastest theoretical and innovative developments in the modeling field and presents some of the most advance applications on various water related topics like uncertainties, flood simulation and complex hydraulic applications. Given its breadth of coverage, it addresses the needs and interests of practitioners, stakeholders, researchers and engineers alike.

Named one of Planetizen's Top 10 Books of 2006 Hurricane Katrina not only devastated a large area of the nation's Gulf coast, it also raised fundamental questions about ways the nation can, and should, deal with the inevitable problems of economic risk and social responsibility. This volume gathers leading experts to examine lessons that Hurricane Katrina teaches us about better assessing, perceiving, and managing risks from future disasters. In the years ahead we will inevitably face more problems like those caused by Katrina, from fire, earthquake, or even a flu pandemic. America remains in the cross hairs of terrorists, while policy makers continue to grapple with important environmental and health risks. Each of these scenarios might, in itself, be relatively unlikely to occur. But it is statistically certain that we will confront such catastrophes, or perhaps one we have never imagined, and the nation and its citizenry must be prepared to act. That is the fundamental lesson of Katrina. The 20 contributors to this volume address questions of public and private roles in assessing, managing, and dealing with risk in American society and suggest strategies for moving ahead in rebuilding the Gulf coast.

Erosion is the most common cause of failures at earth-dams, dikes and levees, whether through overtopping and overflowing, or internal erosion and piping. This book is dedicated to the phenomenon of internal erosion and piping. It is not intended to be exhaustive on the subject, but brings together some of the latest international research and advances. Emphasis is placed on physical processes, how they can be studied in the laboratory, and how test results can be applied to levees and dams. The results from several research projects in Australia, France, the Netherlands and the United States are covered by the authors. Our aim has been to share our most recent findings with students, researchers and practitioners. Understanding the failure of an earth-dam or a levee by erosion in a unified framework, whether internal erosion or surface erosion, requires continuous research in this field. We hope that the reader will gain knowledge from this book that leads to further progress in the challenging field of the safety of levees and dams. Contents 1. State of The Art on the Likelihood of Internal Erosion of Dams and Levees by Means of Testing, Robin Fell and Jean-Jacques Fry. 2. Contact Erosion, Pierre Philippe, Rémi Beguin and Yves-Henri Faure. 3. Backward Erosion Piping, Vera Van Beek, Adam Bezuijen and Hans Sellmeijer. 4. Concentrated Leak Erosion, Stéphane Bonelli, Robin Fell and Nadia Benahmed. 5. Relationship between the Erosion Properties of Soils and Other Parameters, Robin Fell, Gregory Hanson, Gontran Herrier, Didier Marot and Tony Wahl. About the Authors Stéphane Bonelli is a Research Professor at Irstea (French Environmental Sciences and Technologies Research Institute) in Aix-en-Provence, France. He has over 20 years of teaching and research experience, and has been a member of the ICOLD (International Commission on Large Dams) European Working Group on Internal Erosion since 2005. He has participated in 19 large dam reviews in France (visual inspection, monitoring data analysis and numerical modeling). His current activities include research, teaching and consultancy, focusing on soil erosion and the processes of levee breach.

This volume comprises a collection of sixteen national perspectives on law, policy and practice in respect of the underwater cultural heritage, written in light of the UNESCO Convention 2001. The essays provide an up-to-date account of the current legal position in each jurisdiction, as well as considering the impact that the 2001 Convention is having, and is likely to have in the future. As well as being internationally recognised experts in the field, all the contributors have specialist knowledge and practical experience of their own particular jurisdictions.
