Cameron and published by . This book was released on 1988 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies of erosion in unlined emergency spillways channels excavated in rock have demonstrated that erosional processes operating in these spillway channels are similar to those operating in natural stream channels and that rock discontinuities are critical factors in the initiation and extent of erosion. Knickpoint formation and headcutting are typical erosion processes. Fractures, faults, joints, dip orientation, igneous contacts, veins, bedding planes, unconformities, bed pinch outs, and facies changes are types of structural or stratigraphic discontinuities which must be characterized if present. Analysis of 14 Soil Conservation Service and 2 ACE dams which have experienced emergency spillway flow revealed that the extent of erosion at these sites could be categorized in terms of volumetric and horizontal erosion rankings. These ranking parameters provide insight as to the seriousness of the erosion threat at a particular dam and may be used to give priority for remediation. The ranking parameters were more closely correlatable with the geometry of the spillway channel than with the hydraulics of the spillway flow event. Preliminary laboratory studies demonstrated that maximum undermining and erosion of a stratified, two-layer system was a function of the ratio of water depth to knickpoint height and the venting condition of the waterfall. Maximum erosion did not occur at peak discharge but occurred when the discharge passed through windows or thresholds on the rising and falling limbs of the hydrograph which were, in turn, controlled by the ratio (above) and venting.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
