The increasing number of dams built in the last century has underlined the necessity of these constructions to the all-round development of a country. The advent of rock mechanics, engineering geology and a better understanding of materials have made it possible to construct higher and larger dams and to tackle more difficult sites. The assumptions and risks used in the theory of dam design include such unpredictable events as earthquakes, floods, and geological faults or soft seams, which may be either underestimated or completely missed during initial exploration. Incidents relating to dams are manageable at an early stage, whereas accidents, which are largely unforeseen, result in unexpected behaviour of dams and in catastrophic failures. Investigations conducted to determine the cause of a failure may not reveal the true sequence of events, while expert analyses are often controversial. From the dams that do not fail, of course, we learn nothing. Systematically monitoring the dam’s behaviour from the potential risk stage to the accident event, would allow a hazard-management programme to be implemented, minimising loss of life and property, and provide useful data.

Aims to present the data to the profession regarding failures, accidents, and major repairs at dams in the United States. This report analyses data with respect to the type of incident, frequency of incidents, dam size, type of dam, and age of dam. It also draws conclusions and recommendations to help prevent occurrences of similar incidents.

Tailings are the residue of the milling process for extracting metals for ore. They are mostly commonly dumped in surface impoundments (tailing dams), the embankments of which are usually earthfilled dams. In spite of a number of guidelines to their design and construction there are still major failings each year. This book gathers together 221 case records of incidents in attempt to investigate the causes of failure. The main causes were found to be lack of control of water balance, lack of control of construction, lack of understanding of the feature that control safe operation

Residents of areas that could be affected by a dam failure or operational incident have a risk of loss of life, injuries, and damage to property from a failure or operational incident. The purpose of this document is to provide guidelines for the preparation of an Emergency Action Plan (EAP) to facilitate the development of plans that are comprehensive and consistent. The purpose of an EAP is to protect lives and reduce property damage. The intended readers of this document are dam owners and emergency management authorities who work together in the response to dam safety emergencies. An EAP is a formal document that identifies potential emergency conditions at a dam and specifies actions to be followed to minimize loss of life and property damage. The EAP includes: Actions the dam owner will take to moderate or alleviate a problem at the dam Actions the dam owner will take, and in coordination with emergency management authorities, to respond to incidents or emergencies related to the dam

The International Committee on Large Dams (ICOLD) held its 27th International Congress in Marseille, France (12-19 November 2021). The proceedings of the congress focus on four main questions: 1. Reservoir sedimentation and sustainable development; 2. Safety and risk analysis; 3. Geology and dams, and 4. Small dams and levees. The book thoroughly discusses these questions and is indispensable for academics, engineers and professionals involved or interested in engineering, hydraulic engineering and related disciplines.

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.
