The book provides dam engineers and geologists with a practical approach, and gives university students an insight into the subject of dam engineering. All phases of investigation, design and construction are covered, through to the preliminary and detailed design phases and ultimately the construction phase. This revised and expanded 2nd edition includes a lengthy new chapter on the assessment of the likelihood of failure of dams by internal erosion and piping.
Geotechnical Engineering of Dams, 2nd edition provides a comprehensive text on the geotechnical and geological aspects of the investigations for and the design and construction of new dams and the review and assessment of existing dams. The main emphasis of this work is on embankment dams, but much of the text, particularly those parts related to geology, can be used for concrete gravity and arch dams. All phases of investigation, design and construction are covered. Detailed descriptions are given from the initial site assessment and site investigation program through to the preliminary and detailed design phases and, ultimately, the construction phase. The assessment of existing dams, including the analysis of risks posed by those dams, is also discussed. This wholly revised and significantly expanded 2nd edition includes a lengthy new appendix on the assessment of the likelihood of failure of dams by internal erosion and piping. This valuable source on dam engineering incorporates the 200+ years of collective experience of the authors in the subject area. Design methods are presented in combination with their theoretical basis, to enable the reader to develop a proper understanding of the possibilities and limitations of a method. For its practical, well-founded approach, this work can serve as a useful guide for professional dam engineers and engineering geologists and as a textbook for university students.
"This book provides a comprehensive text on the geotechnical and geological aspects of the investigations for and the design and construction of new dams and the review and assessment of existing dams. The emphasis is on embankment dams, but much of the text, particularly those parts related to geology, can be used for concrete gravity and arch dams. The book aims to provide practising dam engineers and geologists with a practical approach, as well as to give university students an insight into the subject of dam engineering. The theoretical basis upon which design methods have been developed is included so readers develop a proper understanding of the limitations of the methods. All phases of investigation, design and construction are covered, from the initial assessment of a damsite and the development and carrying out of a detailed site investigation program, through to the preliminary and detailed design phases and ultimately the construction phase. The assessment of existing dams, including the analysis of risks posed by those dams, is also discussed.

Hydraulic engineering of dams and their appurtenant structures counts among the essential tasks to successfully design safe water-retaining reservoirs for hydroelectric power generation, flood retention, and irrigation and water supply demands. In view of climate change, especially dams and reservoirs, among other water infrastructure, will and have to play an even more important role than in the past as part of necessary mitigation and adaptation measures to satisfy vital needs in water supply, renewable energy and food worldwide as expressed in the Sustainable Development Goals of the United Nations. This book deals with the major hydraulic aspects of dam engineering considering recent developments in research and construction, namely overflow, conveyance and dissipations structures of spillways, river diversion facilities during construction, bottom and low-level outlets as well as intake structures. Furthermore, the book covers reservoir sedimentation, impulse waves and dambreak waves, which are relevant topics in view of sustainable and safe operation of reservoirs. The book is richly illustrated with photographs, highlighting the various appurtenant structures of dams addressed in the book chapters, as well as figures and diagrams showing important relations among the governing parameters of a certain phenomenon. An extensive literature review along with an updated bibliography complete this book.
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.
Geotechnical Engineering of Dams provides a comprehensive text on the geotechnical and geological aspects of the investigations for and the design and construction of new dams. In addition, much attention is paid to the review and assessment of existing dams. The main emphasis of this work is on embankment dams, but much of the text, particularly t
Internal erosion and piping in embankments and their foundations is the main cause of failures and accidents to embankment dams. For new dams, the potential for internal erosion and piping can be controlled by good design and construction of the core of the dam and provision of filters to intercept seepage through the embankment and the foundations
Dams and their auxiliary structures are built to provide water for human consumption, irrigating lands, generating hydroelectric power, and use in industrial processes. They are critical structures for continuing life and providing public safety. Construction of a dam is a complicated task that requires sophisticated modern technology and technical expertise. Scientists need to review and adjust their perspectives on designing embankments and their related structures, and compaction and consolidation of fill material, behavior of concrete materials, geotechnical and seismological studies of the dam site, total risk analysis, safety monitoring and instrumentation, heightening, hydrological studies, soil conservation, and watershed management. This book intends to provide the reader with a comprehensive overview of the latest information in dam engineering.
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.
