Intends to assist the dam owner in evaluating the needs for dam safety improvement, selecting and prioritizing remedial and corrective actions, and improving the operation, maintenance and surveillance procedures. This book is intended not only for industry specialists but also for readers outside the dam engineering community.

This book offers the state of the art on risk analysis, representing a primary tool for achieving effective management of critical infrastructures along with a suitable framework for the development of risk management models regarding natural, technological and human-induced hazards. Essential reading for graduate students and researchers interested in risk analysis as applied to all type of critical infrastructures, and for designers, engineers, owners and operators of critical infrastructures in general and dams in particular.

Dam Safety Management is a major concern during the entire lifetime cycle of a dam scheme. This is particularly true for the operational phase of the scheme that represents by far the longest period in its lifetime cycle. Bulletin 154 presented a general approach and concepts to be applied to dam operation. The current Bulletin 175 extends the developed concepts to all phases preceding the operational phase. Many risks associated with the operation of existing dams have their origins in other phases preceding the actual operation. Although there are numerous ICOLD Bulletins addressing technical aspects of planning, design, construction and commissioning of dams, there is not a single Bulletin which covers the subject in a comprehensive manner. The current document is a first attempt to capture all relevant dam safety aspects in all preoperational phases by systematically characterizing the actors involved, their roles, the activities and complex interactions present in different phases of the dam lifecycle. An Overarching Safety Management System is specifically developed that can be applied to all actors involved. La gestion de la sécurité des barrages est une préoccupation majeure pendant tout le cycle de vie d'un projet de barrage. Cela est particulièrement vrai pour la phase opérationnelle du système qui représente de loin la période la plus longue de son cycle de vie. Le Bulletin 154 présente une approche générale et des concepts à appliquer à l'exploitation des barrages. Le Bulletin 175 actuel étend les concepts développés à toutes les phases précédant la phase d'exploitation. De nombreux risques associés à l'exploitation des barrages existants ont leur origine dans d'autres phases précédant l'exploitation proprement dite. Bien qu'il existe de nombreux bulletins ICOLD traitant des aspects techniques de la planification, de la conception, de la construction et de la mise en service des barrages, il n'existe pas un seul bulletin qui couvre le sujet de manière exhaustive. Le document actuel est une première tentative de capturer tous les aspects pertinents de la sécurité des barrages dans toutes les phases pré-opérationnelles en caractérisant systématiquement les acteurs impliqués, leurs rôles, les activités et les interactions complexes présentes dans les différentes phases du cycle de vie du barrage. Un système global de gestion de la sécurité est spécifiquement développé et peut être appliqué à tous les acteurs impliqués.

From earth tectonics and meteorology to risk, responsibility, and the role of government, this comprehensive and detailed book reviews current practices in designing dams to withstand extreme hydrologic and seismic events. Recommendations for action and for further research to improve dam safety evaluations are presented.

Although advances in engineering can reduce the risk of dam and levee failure, some failures will still occur. Such events cause impacts on social and physical infrastructure that extend far beyond the flood zone. Broadening dam and levee safety programs to consider community- and regional-level priorities in decision making can help reduce the risk of, and increase community resilience to, potential dam and levee failures. Collaboration between dam and levee safety professionals at all levels, persons and property owners at direct risk, members of the wider economy, and the social and environmental networks in a community would allow all stakeholders to understand risks, shared needs, and opportunities, and make more informed decisions related to dam and levee infrastructure and community resilience. Dam and Levee Safety and Community Resilience: A Vision for Future Practice explains that fundamental shifts in safety culture will be necessary to integrate the concepts of resilience into dam and levee safety programs.

Communication of risks within a transparent and accountable framework is essential in view of increasing mobility and the complexity of the modern society and the field of geotechnical engineering does not form an exception. As a result, modern risk assessment and management are required in all aspects of geotechnical issues, such as planning, design, construction of geotechnical structures, mitigation of geo-hazards, management of large construction projects, maintenance of structures and life-cycle cost evaluation. This volume discusses: 1. Evaluation and control of uncertainties through investigation, design and construction of geotechnical structures; 2. Performance-based specifications, reliability based design and limit state design of geotechnical structures, and design code developments; 3. Risk assessment and management of geo-hazards, such as landslides, earthquakes, debris flow, etc.; 4. Risk management issues concerning large geotechnical construction projects; 5. Repair and maintenance strategies of geotechnical structures. Intended for researchers and practitioners in geotechnical, geological, infrastructure and construction engineering.
