Dam Engineering


Book Description

Dams are critical structures in the sense that damage or breach of even a small dam may cause an unacceptable loss of life and property. Therefore, the safety of dams over the intended lifespan is of utmost importance for unrestricted operation. The basic prerequisites for any safe and successful operation of a dam include state-of-the-art design, experimental investigations of the construction material and properties of the foundation, a refined theoretical analysis of relevant load cases, and high-quality construction. In the past decades, many advancements have been achieved in both construction technologies and design, including those for the prediction of the long-term behavior of dams under various loading conditions. As such, this book examines these advancements with respect to the design, construction, and performance of earth, rockfill, and concrete dams. Over eight chapters, this book provides a comprehensive overview of the latest progress and research in dam engineering.

New Developments in Dam Engineering


Book Description

The development of water resources is a key element in the socio-economic development of many regions in the world. Water availability and rainfall are unequally distributed both in space and time, so dams play a vital role, there being few viable alternatives for storing water. Dams hold a prime place in satisfying the ever-increasing demand for power, irrigation and drinking water, for protection of man, property and environment from catastrophic floods, and for regulating the flow of rivers. Dams have contributed to the development of civilization for over 2,000 years. Worldwide there are some 45,000 large dams listed by ICOLD, which have a height over 15 meters. Today, in western countries, where most of the water resources have been developed, the safety of the existing dams and measures for extending their economical life are of prime concern. In developing countries the focus is on the construction of new dams. The proceedings of the 4th International Conference on Dam Engineering includes contributions from 18 countries, and provides an overview of the state-of-the-art in hydropower development, new type dams, new materials and new technologies, dam and environment. Traditional areas, such as concrete dams and embankment dams, methods of analysis and design of dams, dam foundation, seismic analysis, design and safety, stability of dam and slope, dam safety monitoring and instrumentation, dam maintenance, and rehabilitation and heightening are also considered. The book is of special interest to scientists, researchers, engineers, and students working in dam engineering, dam design, hydropower development, environmental engineering, and structural hydraulics.




Engineering and Design


Book Description

1-1. Purpose This manual presents fundamental principles underlying the design and construction of earth and rock-fill dams. The general principles presented herein are also applicable to the design and construction of earth levees. The construction of earth dams by hydraulic means was curtailed in the 1940's due to economic considerations and liquefaction concerns during earthquake loading and are not discussed herein. 1-2. Applicability This manual applies to HQUSACE elements, major subordinate commands, districts, laboratories, and field operating activities having responsibility for the design and construction of earth and rock-fill dams. 1-3. References Required and related publications are listed in Appendix A. 1-4. Overview of Manual The objective of this manual is to present guidance on the design, construction, and performance monitoring of and modifications to embankment dams. The manual presents general guidance and is not intended to supplant the creative thinking and judgment of the designer for a particular project. The increased development and expansion of the population in the Nation's watersheds have created a definite need to develop additional water supply. In many areas the existing national infrastructure cannot meet these needs. The increase in urban development has also had a negative impact on water quality. The public is asking that preservation of the environment be an equal goal with the economic benefits of water resources projects. Since the current infrastructure is not meeting public needs, this situation is placing lives, livelihood, and property at risk. Several options are available to provide the additional quantity of water. The simplest and most cost-effective method to obtain the quantities needed is to add additional storage at existing dams. Many of the Nation's existing water resources projects must be modified to add the additional purpose of water supply. In the future, USACE designers will be challenged with requests by the customers and sponsors to modify existing dams to add water supply to other purposes of existing dams. These modifications must include environmental considerations and mitigation.

Advances in Dam Engineering


Book Description

Expansion of water resources is a key factor in the socio-economic development of all countries. Dams play a critical role in water storage, especially for areas with unequal rainfall and limited water availability. While the safety of existing dams, periodic re-evaluations and life extensions are the primary objectives in developed countries, the design and construction of new dams are the main concerns in developing countries. The role of dam engineers has greatly changed over recent decades. Thanks to new technologies, the surveillance, monitoring, design and analysis tasks involved in this process have significantly improved. The current edited book is a collection of dam-related papers. The overall aim of this edited book is to improve modeling, simulation and field measurements for different dam types (i.e. concrete gravity dams, concrete arch dams, and embankments). The articles cover a wide range of topics on the subject of dams, and reflect the scientific efforts and engineering approaches in this challenging and exciting research field.




Tailings Dam Design / Conception des Barrages de Stériles Miniers


Book Description

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.
