Dam Safety Management / Gestion de la Sécurité des Barrages Pre operational phases of the dam life cycle / Phases de conception constructio

Dam Safety Management / Gestion de la Sécurité des Barrages Pre operational phases of the dam life cycle / Phases de conception constructio

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. | Dam Safety Management / Gestion de la Sécurité des Barrages Pre operational phases of the dam life cycle / Phases de conception constructio

The Grand Ethiopian Renaissance Dam and the Nile Basin Implications for Transboundary Water Cooperation

The Grand Ethiopian Renaissance Dam and the Nile Basin Implications for Transboundary Water Cooperation

The Grand Ethiopian Renaissance Dam (GERD) will not only be Africa’s largest dam but it is also essential for future cooperation and development in the Nile River Basin and East African region. This book after setting out basin-level legal and policy successes and failures of managing and sharing Nile waters articulates the opportunities and challenges surrounding the GERD through multiple disciplinary lenses. It sets out its possibilities as a basis for a new era of cooperation its regional and global implications the benefits of cooperation and coordination in dam filling and the need for participatory and transparent decision making. By applying law political science and hydrology to sharing water resources in general and to large-scale dam building filling and operating in particular it offers concrete qualitative and quantitative options that are essential to promote cooperation and coordination in utilising and preserving Nile waters. The book incorporates the economic dimension and draws on recent developments including: the signing of a legally binding contract by Egypt Ethiopia and Sudan to carry out an impact assessment study; the possibility that the GERD might be partially operational very soon the completion of transmission lines from GERD to Addis Ababa; and the announcement of Sudan to commence construction of transmission lines from GERD to its main cities. The implications of these are assessed and lessons learned for transboundary water cooperation and conflict management. | The Grand Ethiopian Renaissance Dam and the Nile Basin Implications for Transboundary Water Cooperation

Downstream Consequences of Ribb River Damming Lake Tana Basin Ethiopia

Downstream Consequences of Ribb River Damming Lake Tana Basin Ethiopia

This study assessed the downstream river system adaptation in response to upstream damming on the Ribb River Ethiopia to irrigate 15 000 ha. It combined primary and secondary data and the application of remote sensing and mathematical modeling. The pre-dam morphodynamic trends of the Ribb River were analyzed for 59 years based on aerial photographs satellite images and newly collected field data. Three dam operation scenarios were developed to analyze the long-term hydro-morphological effects of the dam on the downstream river reaches. It also assessed the applicability of physics-based analytical equations (Equilibrium Theory) compared to a 1D numerical model (SOBEK-RE) to determine the least-morphologically impactful dam operation scenario on the river reaches downstream of the dam. Moreover a HEC-RAS 2D hydrodynamic model was developed to assess the effect of the dam on the flooding extent of the Fogera Plain. This was used to study the potential implications of hydrological alteration on the ecology of the floodplain wetlands as they are the habitats of important fish and bird species. The results contribute to knowledge on the hydro-morphological and environmental impacts of dams on downstream river systems. The developed methodologies and findings may be used to study future hydro-morphological and ecological changes that may arise due to other dam operations or climate change. | Downstream Consequences of Ribb River Damming Lake Tana Basin Ethiopia

Tailings Dam Design / Conception des Barrages de Stériles Miniers Technology Update / Mise à Jour des Technologies

Tailings Dam Design / Conception des Barrages de Stériles Miniers Technology Update / Mise à Jour des Technologies

Tailings are produced from the processing of mineral ores and are commonly stored within embankment dams. The design of the dams requires application of sound engineering principles and an understanding of the properties of the tailings. This Bulletin provides a framework for classifying different types of tailings ranging from ultra-fine to coarse based on their geotechnical properties and provides typical geotechnical parameters for the different tailings types. Technologies for dewatering tailings to reduce the risk of storage continue to be developed and the different technologies from thickening to filtration and re-application of old technologies are presented to illustrate the options available and where appropriate typical in situ properties. This bulletin is directed towards a wide audience of stakeholders: designers owners regulators communities and various organizations and provides a reference for communicating tailings properties and the benefits and limitations of technologies. All mining operations and thereby tailings operations are unique. There is no one-solution-fits-all. Tailings dam designs need to account for site-specific conditions such as climate physiography geochemistry geomorphology seismology mining processes environment and community setting with the application of technologies playing an important role in developing safe sustainable tailings facilities. Les stériles miniers sont produits à partir du traitement des minerais et sont généralement stockés derrière des barrages en remblai. La conception des barrages nécessite l'application de principes d'ingénierie solides et une compréhension des propriétés des résidus. Ce bulletin fournit un cadre pour classer différents types de résidus allant de l'ultra-fin au grossier en fonction de leurs propriétés géotechniques et propose des paramètres géotechniques typiques pour les différentes sortes de résidus. Les technologies d'assèchement des résidus pour réduire le risque de stockage continuent à être développées ; les différentes technologies de l'épaississement à la filtration en passant par l’application des anciennes technologies sont présentées pour illustrer les options disponibles et le cas échéant les propriétés in situ typiques. Ce bulletin s'adresse à un large public d'intervenants : concepteurs propriétaires régulateurs communautés et organisations diverses et fournit une référence pour communiquer les propriétés des résidus et les avantages et les limites des technologies. Toutes les opérations minières et par conséquent les traitements des résidus sont uniques. Il n'y a pas de solution unique pour tous. La conception des barrages de résidus doit tenir compte des conditions propres au site telles que le climat la physiographie la géochimie la géomorphologie la sismologie les processus miniers l'environnement et le milieu communautaire l'application de technologies jouant un rôle important dans le développement de parcs à résidus sûrs et durables. | Tailings Dam Design / Conception des Barrages de Stériles Miniers Technology Update / Mise à Jour des Technologies

Labyrinth and Piano Key Weirs III Proceedings of the 3rd International Workshop on Labyrinth and Piano Key Weirs (PKW 2017) February 22-24

Since the first implementation by Electricité de France on the Goulours dam (France) in 2006 the Piano Key Weir has become a more and more applied solution to increase the discharge capacity of existing spillways. In parallel several new large dam projects have been built with such a flood control structure usually in combination with gates. Today more than 25 Piano Key Weirs are in operation or under construction all over the world. More than 15 years of research and development have enabled detailed investigations of the hydraulic and structural behaviour of the Piano Key Weir complex structure and have provided more and more accurate design equations. Following the proceedings of the first two workshops held in Liege (Belgium – 2011) and Paris (France – 2013) Labyrinth and Piano Key Weirs III collects the contributions presented by people with varied background from researchers to practitioners at the 3rd International Workshop on Labyrinth and Piano Key Weirs - PKW 2017 (22-24 February 2017 Qui Nhon Vietnam). The papers reviewed and accepted by an International Scientific Committee summarize the current state-of-the-art on Piano Key Weirs from a theoretical to a practical point of view and present most of the main projects in operation or under construction. Labyrinth and Piano Key Weirs III is thus a reference for students practitioners and researchers interested in Dams Engineering. | Labyrinth and Piano Key Weirs III Proceedings of the 3rd International Workshop on Labyrinth and Piano Key Weirs (PKW 2017) February 22-24

Environmental Fluid Mechanics - Méchanique des Fluides Environnementaux

Dams are planned constructed and operated to meet human needs - generation of energy irrigated agricultural production flood control public and industrial supply supply of drinking water and various other purposes. Dams impound water in reservoirs during times of high flood that can be used for human requirements during times with inadequate natural flows. Positive impacts of dams are improved flood control improved welfare resulting from new access to irrigation and drinking water. Without dams there would be insufficient food to feed the world’s people and energy would be generated by burning fossil fuels that produce greenhouse gases. Despite this progress there remain significant concerns about the environmental impacts of dams. These environmental impacts are complex and far reaching remote of the dam and may occur in time with the dam construction or later and may lead to a loss of biodiversity and of productivity of natural resources. This bulletin compiles improvements in knowledge and state of the art technology to avoid or mitigate environmental impacts of dams on the natural ecosystem as well as to the people that depend upon them for their livelihood and also addresses the mitigation of environmental impacts on dams and reservoirs. Les barrages sont planifiés construits et exploités de manière à répondre aux besoins humains. Les barrages retiennent l'eau dans les réservoirs pendant les périodes de forte crue une eau qui peut être utilisée pour les besoins de l'homme pendant les périodes d’insuffisance des débits naturels. Les impacts positifs de barrages sont le contrôle des crues et l'amélioration du bien-être résultant du nouvel accès à l'irrigation et à l'eau potable. Sans barrages la production alimentaire serait insuffisante pour nourrir la population du globe et l'énergie serait générée en brûlant des combustibles fossiles qui produisent des gaz à effet de serre. Malgré ces progrès d'importantes préoccupations subsistent quant aux retombées des barrages sur l’environnement. Les impacts environnementaux sont complexes et d’une grande portée. Ils peuvent se produire au moment de la construction du barrage ou plus tard et peuvent entraîner une perte de la biodiversité et de la productivité des ressources naturelles. Le présent bulletin compile l'amélioration des connaissances et des technologies les plus récentes pour éviter ou atténuer les impacts environnementaux des barrages sur l'écosystème naturel ainsi que pour les personnes qui en dépendent pour leur subsistance. Il aborde également l'atténuation des impacts environnementaux sur les barrages et les réservoirs. | Environmental Fluid Mechanics - Méchanique des Fluides Environnementaux

Soil Engineering Testing Design and Remediation

Soil Engineering Testing Design and Remediation

In the last forty years at least fifty books have been written on the subject of soil mechanics most of them textbooks. Only a few touch on practical applications. Soil Engineering: Testing Design and Remediation supplies the information needed to fill the gap between textbook learning and practical know-how. When engineers deal with major projects such as the Teton Dam or the Leaning Tower of Pisa they need high-tech solutions. More often than not however they deal with the foundations for warehouses schools medium-rise buildings and residential structures projects that need low-tech solutions. Ninety percent of the time consulting engineers don't require mathematical treatment or computer analysis they require experience. Soil engineering problems cannot be resolved with textbook information alone. This book provides the practical meaning of the different aspects of soil mechanics the use of unconfined compression test data the meaning of consolidated tests the practical value of lateral pressure and more. In addition to the technical aspects of foundation investigation in the real world the shadow of litigation looms over every consultant's head. The author covers legal issues in detail. After several years in foundation investigation most consultants realize that soil engineering is a combination of art and science. Soil Engineering: Testing Design and Remediation demystifies this connection and supplies real-world examples of practical applications. This hands-on ready reference will be essential tool for any consultant working in the field. | Soil Engineering Testing Design and Remediation
