Tidal


Book Description

Gemma is facing the fight of her life. Cursed by beautiful but deadly sirens, her extraordinary powers have a terrifyingly dark side, and becoming human once more is proving her greatest challenge yet. As she struggles to break the curse, the sirens, Penn Lexi and Thea are determined to kill her before she can set herself free. Gemma's only allies are her sister, Harper, and Harper's boyfriend, Daniel. Together they must delve into their enemies' mythical pasts -- to discover their darkest secrets. But Penn has also set her sights on Daniel. Soon, the sirens threaten everything Gemma holds dear: her family, her friends, her life, and her relationship with Alex -- the only guy she has ever loved. Can she save herself and those she cares about before it is too late?




Major Biological Processes in European Tidal Estuaries


Book Description

Nineteen papers representing the results of a project funded by the Commission of the European Communities to study macrotidal estuaries from the Elbe to the Tagus in a comparative and coherent manner by way of a standardized methodology. The papers address topics in primary production, bacterial processes, zooplankton, hyperbenthos, meiobenthos, macrobenthos, and modeling. A major result of the comparison is that salinity gradients explain species succession within each estuary, yet similar succession series are found at different salinity levels in different estuaries. The volume is reprinted from Hydrobiologia, v.311, 1995. Includes graphs and maps. Lacks an index. Annotation copyright by Book News, Inc., Portland, OR




Tidal Current Tables


Book Description

Contains daily predicted times of slack water and predicted times and velocities of maximum current.




The Analysis of Tidal Stream Power


Book Description

This text integrates a wide range of research and tidal resource theory and data to present a detailed analysis of the physics and oceanography of tidal stream power devices together with a world wide resource analysis. Clearly structured throughout the book is divided into two distinct parts. Part One provides the theoretical background to the subject and deals with the historical development of the harmonic method for the synthesis of tidal currents; the principles of fluid and tidal flow and the principles of device ducts, turbines and electrical systems. A review and analysis of more than forty tidal stream power proposals is also discussed. Part Two provides a comprehensive overview of current practice. The economic modelling of tidal stream power installations is covered with more than three hundred current meter records from around the world used to analyse the potential and cost of tidal stream power on a global basis. Hallmark Features: reviews the tidal resources around the world complete analysis of tidal stream power systems includes historical information on tidal science and biographical information on major figures concentrates on engineering physical geography rather than engineering specifics includes a website with a wide range of computer models, data and simulations




Tidal Energy Systems


Book Description

Tidal Energy Systems: Design, Optimization and Control provides a comprehensive overview of concepts, technologies, management and the control of tidal energy systems and tidal power plants. It presents the fundamentals of tidal energy, including the structure of tidal currents and turbulence. Technology, principles, components, operation, and a performance assessment of each component are also covered. Other sections consider pre-feasibility analysis methods, plant operation, maintenance and power generation, reliability assessment in terms of failure distribution, constant failure rate and the time dependent failure model. Finally, the most recent research advances and future trends are reviewed. In addition, applicable real-life examples and a case study of India's tidal energy scenario are included. The book provides ocean energy researchers, practitioners and graduate students with all the information needed to design, deploy, manage and operate tidal energy systems. Senior undergraduate students will also find this to be a useful resource on the fundamentals of tidal energy systems and their components. - Presents the fundamentals of tidal energy, including system components, pre-feasibility analysis, and plant management, operations and control - Explores concepts of sustainability and a reliability analysis of tidal energy systems, as well as their economic aspects and future trends - Covers the assessment of tidal energy systems by optimization technique and game theory




Elements of Tidal-Electric Engineering


Book Description

The first text to cover all stages of a tidal-electric feasibility study As interest in tidal-electric power generation continues to grow in response to demands for renewable sources of energy, readers can now turn to Elements of Tidal-Electric Engineering for the first comprehensive treatment of the subject. The author, Robert H. Clark, a leader in the field for almost fifty years, has spearheaded several important research projects and consulted with governments and private industries around the world on tidal-electric issues. The focus of this text is the feasibility study. Power engineers gain both the knowledge and the skills needed to accurately determine the feasibility of a proposed tidal power development plan, including: * Major factors to consider in selecting a site for preliminary assessment * Tidal power schemes and mode * Hydraulic and mathematical models of estuaries to predict the estuary's response to physical changes and the effects caused by operation of the proposed plant * Civil works required for tidal power development and the associated tidal generating equipment * Procedures to optimize plant output * Economic evaluation and risk assessment * Environmental impact of proposed construction and operation The book ends with an examination of commercially operating plants and a brief review of sites that have been the subject of investigation in the last half century. References and bibliographies direct readers to primary source material for further study. Until publication of this text, power engineers have had to rely on random journal articles and anecdotal information to perform a feasibility investigation. With the publication of Elements of Tidal-Electric Engineering these engineers have a single, integrated source that methodically covers all the issues.
