The reader is guided through different aspects of dams and appurtenant hydraulic structures in 35 chapters, which are subdivided in five themes:
I. Dams and appurtenant hydraulic structures – General;
II. Embankment dams;
III. Concrete dams;
IV. Hydromechanical equipment and appurtenant hydraulic structures;
V. Hydraulic schemes.
Subjects treated are general questions, design, construction, surveillance, maintenance and reconstruction of various embankment and concrete dams, hydromechanical equipment, spillway structures, bottom outlets, special hydraulic structures, composition of structures in river hydraulic schemes, reservoirs, environmental effects of river hydraulic schemes and reservoirs and environmental protection. Special attention is paid to advanced methods of static and dynamic analysis of embankment dams.
The wealth of experience gained by the author over the course of 35 years of research and practice is incorporated in this richly-illustrated, fully revised, updated and expanded edition. For the original Macedonian edition of Dams and Appurtenant Hydraulic Structures, Ljubomir Tanchev was awarded the Goce Delchev Prize, the highest state prize for achievements in science in the Republic of Macedonia.
This work is intended for senior students, researchers and professionals in civil, hydraulic and environmental engineering and dam construction and exploitation.
Ljubomir Tanchev was born in 1945 in Prilep (Republic of Macedonia). He moved to Skopje in 1950 where he finished the primary and secondary school and graduated in Civil Engineering from the Sts Cyril and Methodius University, Skopje. He obtained his M.Sc. in 1980 and was awarded his Ph.D. on the subject of Numerical analysis of embankment dams from the same university in 1987. In 1978/79 he completed a post-graduate study at IHE in Delft, The Netherlands.
He began his career working in the laboratory for testing of materials of the CC "Mavrovo" (Skopje) as a research engineer between 1972 and 1977. Then he joined the Sts Cyril and Methodius University, Faculty of Civil Engineering, as assistant. In 1988 he was appointed Assistant Professor, in 1992 Associate Professor and in 1996 Professor, covering the topics of Dams and Hydraulic Structures. He has been Head of the Department of Hydraulic Structures, vice-Dean and from October 1999 till October 2003 Dean of the Faculty of Civil Engineering, Sts Cyril and Methodius University. He retired in October 2010, but is still active in various projects. He was president of the Macedonian Committee on Large Dams (a member of ICOLD) from May 2004 till June 2013.
Over his 40 years of practice, Professor Tanchev has been involved in many hydraulic engineering projects as a designer, consultant, and supervisor. He has published more than 50 scientific works and he is the author of three books published in Macedonian: Static analysis of embankment dams (1989), Hydraulic structures (1992) and Dams and appurtenant hydraulic structures (1999). For the latter book, Prof. Tanchev was awarded the Goce Delchev Prize, the highest state prize for achievement in the sciences. The first English edition of Dams and Appurtenant Hydraulic Structures was published in 2005 by CRC Press / Balkema.
This third edition is broader in scope and includes new chapters on water resources engineering and water security. Civil engineers may also find it a useful introduction to complement the more rigorous hydraulics textbooks.
Over the last 20 years, active research has been carried out in the field, resulting in practical results in phenomena interpretation and dam modeling. At the same time, an increasing number of affected dams have undergone safety re-evaluations and in some cases remedial work. Several of them have been removed altogether. Although it remains difficult to establish a “state of the art” in this domain due to the rapidly changing context, regular international exchanges in the field appear fruitful and necessary.
Following on from previous conferences in the field organized by Robin Charlwood, former President of the ICOLD Concrete Committee, the initiative was taken by EDF and Toulouse University-LMDC to organize a workshop to provide a new opportunity for sharing experience. The aim of this workshop is to assemble active researchers, leading engineers, and experts from the practicing community and administration interested directly or indirectly in concrete swelling effects in dams and hydraulic structures. All types of chemical expansion phenomena, including those due to alkali aggregate reactions and those due to ettringite formation, are addressed.
These proceedings include 24 papers written by experts renowned in their field, illustrating the need to progress with interdisciplinary approaches.
"I wait for new Smil books the way some people wait for the next 'Star Wars' movie. In his latest book, Energy and Civilization: A History, he goes deep and broad to explain how innovations in humans' ability to turn energy into heat, light, and motion have been a driving force behind our cultural and economic progress over the past 10,000 years.
—Bill Gates, Gates Notes, Best Books of the Year
Energy is the only universal currency; it is necessary for getting anything done. The conversion of energy on Earth ranges from terra-forming forces of plate tectonics to cumulative erosive effects of raindrops. Life on Earth depends on the photosynthetic conversion of solar energy into plant biomass. Humans have come to rely on many more energy flows—ranging from fossil fuels to photovoltaic generation of electricity—for their civilized existence. In this monumental history, Vaclav Smil provides a comprehensive account of how energy has shaped society, from pre-agricultural foraging societies through today's fossil fuel–driven civilization.
Humans are the only species that can systematically harness energies outside their bodies, using the power of their intellect and an enormous variety of artifacts—from the simplest tools to internal combustion engines and nuclear reactors. The epochal transition to fossil fuels affected everything: agriculture, industry, transportation, weapons, communication, economics, urbanization, quality of life, politics, and the environment. Smil describes humanity's energy eras in panoramic and interdisciplinary fashion, offering readers a magisterial overview. This book is an extensively updated and expanded version of Smil's Energy in World History (1994). Smil has incorporated an enormous amount of new material, reflecting the dramatic developments in energy studies over the last two decades and his own research over that time.
In UNSTOPPABLE, Bill Nye crystallizes and expands the message for which he is best known and beloved. That message is that with a combination of optimism and scientific curiosity, all obstacles become opportunities, and the possibilities of our world become limitless. With a scientist's thirst for knowledge and an engineer's vision of what can be, Bill Nye sees today's environmental issues not as insurmountable, depressing problems but as chances for our society to rise to the challenge and create a cleaner, healthier, smarter world. We need not accept that transportation consumes half our energy, and that two-thirds of the energy you put into your car is immediately thrown away out the tailpipe. We need not accept that dangerous emissions are the price we must pay for a vibrant economy and a comfortable life. Above all, we need not accept that we will leave our children a planet that is dirty, overheated, and depleted of resources. As Bill shares his vision, he debunks some of the most persistent myths and misunderstandings about global warming. When you are done reading, you'll be enlightened and empowered. Chances are, you'll be smiling, too, ready to join Bill and change the world.
In Unstoppable: Harnessing Science to Change the World, the New York Times bestselling author of Undeniable: Evolution and the Science of Creation and former host of "Bill Nye the Science Guy" issues a new challenge to today's generation: to make a cleaner, more efficient, and happier world.
Praise for UNDENIABLE:
"With his charming, breezy, narrative style, Bill empowers the reader to see the natural world as it is, not as some would wish it to be. He does it right. And, as I expected, he does it best." -Neil deGrasse Tyson, Ph.D, host of COSMOS
"Bill Nye, 'the Science Guy,' has become a veritable cultural icon....[T]he title of his new book on evolution...[is] 'Undeniable,' because, yes, there are many Americans who still deny what Darwin and other scientists long ago proved." -Frank Bruni, The New York Times
"With a jaunty bow tie and boyish enthusiasm, Bill Nye the Science Guy has spent decades decoding scientific topics, from germs to volcanoes, for television audiences....In his new book, Nye delights in how [evolution] helps to unlock the mysteries of everything from bumblebees to human origins to our place in the universe." -National Geographic
"When it comes to Bill Nye, 'Science Guy' doesn't even begin to cover it. When he's not being summoned to act as a voice of reason for news outlets or leading meetings as CEO of the Planetary Society, he is living the life of a best-selling author....His recently published book, 'Undeniable: Evolution and the Science of Creation,' enlightens readers while using a conversational, educational tone. After all, it's his ability to break down even the most complicated topics into bite-size pieces that made him such a hit on his '90s children's show 'Bill Nye, the Science Guy.'" -The Boston Globe
"Mr. Nye writes briskly and accessibly...[and] makes an eloquent case for evolution."-The Wall Street Journal
"Because [Bill Nye is] a scientist, he has no doubts that the 'deniers' of evolution are flat wrong. And because he's a performer, his book is fun to read and easy to absorb." -The Washington Post
"Ignite your inner scientist when Nye, known for delivering geeky intel with clarity and charm, takes on one of society's most hotly debated topics (yes, still)." -Time Out New York
