This book was released on 1994-01-01 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prepared by the Task Committee on Overtopping Protection of the Hydraulics Division of ASCE. This report summarizes the results of an inventory and evaluation of innovative spillway designs and overtopping protection systems developed to provide cost-effective safety modifications for existing dams. The information in this report, which covers pertinent projects in all stages from initial design through construction and operation, was derived from a literature search and a direct survey of the engineering community involved in dam safety modifications. The report contains a brief review of procedures to be used for assessment of the consequences of dam failure and the associated risks is presented for development of the design flood. This is followed by a discussion of innovative spillway designs and the state of the art in dam overtopping protection alternatives. ForØspillway design, this report especially focuses on the use of labyrinth spillways and fuseplug embankments. For overtopping protection systems, the report assesses roller-compacted concrete and precast concrete blocks for smaller dams and cast-in-place reinforced concrete slabs for larger dams. Nonstructural alternatives such as revised reservoir operating requirements and downstream early warning systems are also addressed.

Book excerpt: 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 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.

Download or read book Dams and Reservoirs in Evaporites written by Petar Milanović and published by Springer. This book was released on 2019-05-25 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book shares essential insights on evaporites and their effects on dams and reservoirs. The intensity of the solution and suffusion process in evaporites (gypsum and salt) is much greater than the solution of carbonates, and evaporites are particularly vulnerable at dam and reservoir sites. Moreover, the presence of evaporites in the vicinity of dams or reservoirs often leads to serious problems: numerous dams in countries around the world (e.g. China, Germany, Iran, Iraq, Peru, Russia, Spain, the Unites States, and Venezuela) have been affected by evaporite dissolution problems. Several of these dams were seriously endangered or ultimately abandoned, even though the best available engineering prevention and remediation practices were applied. Conventional geotechnical methods based on treating the underground (e.g. grout curtains) or surface (e.g. protective blankets) were not successful. This book presents and analyzes revealing case studies in this regard. To improve geotechnical remediation in connection with preventing seepage from reservoirs situated in evaporites, particularly in gypsum, it puts forward a new chemical solution that, after painstaking laboratory testing, was successfully applied in the field.

Download or read book Karst Management written by Philip E. van Beynen and published by Springer Science & Business Media. This book was released on 2011-06-21 with total page 490 pages. Available in PDF, EPUB and Kindle. Book excerpt: Focusing specifically on the management of karst environments, this volume draws together the world’s leading karst experts to provide a vital source for the study and management of this unique physical setting. Although karst landscapes cover 12% of the Earth’s terrain and provide 25% of the world’s drinking water, the resource management of karst environments has only previously received indirect attention. Through a comprehensive approach, Karst Management focuses on engineering issues associated with surface karst such as quarries, dams, and agriculture, subsurface topics such as the management of groundwater, show caves, cave biota, and geo-archaeology projects. Chapters that focus on karst as an integrated system look at IUCN World Heritage sites, national parks, policy and regulation, measuring systematic disturbance, information management, and public environmental education. The text incorporates the most up-to-date research from leading karst scientists. This volume provides important perspectives for university students, educators, geoengineers, resource managers, and planners who are interested in or work with this unique physical landscape.

Download or read book Comparative Indo European Linguistics written by Robert S.P. Beekes and published by John Benjamins Publishing. This book was released on 2011-10-18 with total page 441 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives a comprehensive introduction to Comparative Indo-European Linguistics. It starts with a presentation of the languages of the family (from English and the other Germanic languages, the Celtic and Slavic languages, Latin, Greek and Sanskrit through Armenian and Albanian) and a discussion of the culture and origin of the Indo-Europeans, the speakers of the Indo-European proto-language.The reader is introduced into the nature of language change and the methods of reconstruction of older language stages, with many examples (from the Indo-European languages). A full description is given of the sound changes, which makes it possible to follow the origin of the different Indo-European languages step by step. This is followed by a discussion of the development of all the morphological categories of Proto-Indo-European. The book presents the latest in scholarly insights, like the laryngeal and glottalic theory, the accentuation, the ablaut patterns, and these are systematically integrated into the treatment. The text of this second edition has been corrected and updated by Michiel de Vaan. Sixty-six new exercises enable the student to practice the reconstruction of PIE phonology and morphology.

Download or read book Fossil Horses of South America written by José Luis Prado and published by Springer. This book was released on 2017-04-25 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an update on the phylogeny, systematics and ecology of horses in South America based on data provided over the past three decades. The contemporary South American mammalian communities were shaped by the emergence of the Isthmus of Panama and by the profound climatic oscillations during the Pleistocene. Horses were a conspicuous group of immigrant mammals from North America that arrived in South America during the Pleistocene. This group is represented by 2 genera, Hippidion and Equus, which include small species (Hippidion devillei, H. saldiasi, E. andium and E. insulatus) and large forms (Equus neogeus and H. principale). Both groups arrived in South America via 2 different routes. One model designed to explain this migration indicates that the small forms used the Andes corridor, while larger horses used the eastern route and arrived through some coastal areas. Molecular dating (ancient DNA) suggests that the South American horses separated from the North American taxa (caballines and the New World stilt-legged horse) after 3.6 - 3.2 Ma, consistent with the final formation of the Panamanian Isthmus. Recent studies of stable isotopes in these horses indicate an extensive range of 13C values cover closed woodlands to C4 grasslands. This plasticity agrees with the hypothesis that generalist species and open biome specialist species from North America indicate a positive migration through South America.
