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 worldcomplete analysis of tidal stream power systemsincludes historical information on tidal science and biographical information on major figuresconcentrates on engineering physical geography rather than engineering specificsincludes a website with a wide range of computer models, data and simulations

Estuaries are complex and fascinating natural environments, where constantly changing water depths generate rapidly reversing currents and transport vast quantities of salt, heat, and sediment on a daily basis. Estuaries: Monitoring and Modeling the Physical System examines these processes, offering extensive information about the geological evolution of estuaries, and details of bathymetry, tides, currents, salt and heat, and suspended sediment. By carefully building a working computer model which accurately emulates the complexities inherent in estuaries, students learn quickly to model the tides and currents, and then to build and test salinity, temperature, and suspended sediment modules. The book is strongly supported by a website at www.blackwellpublishing.com/hardisty which includes: Regularly updated Dynamic Internet References Excel routines for individual formulae and diagrams Full coding for the estuarine model THE ANALYSIS OF TIDAL STREAM POWER - For Jack Hardisty's new book and the accompanying website please click here: http://eu.wiley.com/WileyCDA/WileyTitle/productCd-047072451X.html

Computerised Environmental Modelling A Practical Introduction Using Excel J. Hardisty, D. M. Taylor and S. E. Metcalfe The University of Hull, UK The study of the environment is currently developing into a rigorous and demanding analytical science that requires the use of sophisticated environmental models. The increasing demand for graduates trained to deal with complex environmental issues gives rise to the problem of how environmental modelling should be taught. Computerised Environmental Modelling, which is based upon an existing undergraduate course, addresses this problem by presenting a readable (and tested) introduction to the subject through an easy to use software environment. Simple numerical models taught through widely available spreadsheets do away with the need for language-specific training. Students now no longer need to program before they can model. Divided into three sections, the book first deals with the general principles of environmental systems modelling, then with a series of examples that familiarise the reader with the use of spreadsheets (in particular with Excel). Finally a set of new and topical environmental models are presented, including ocean, meteorological, hydrological, and extinction models. A supplementary disk, which holds all the programs discussed in the text, can be purchased upon request by returning the reply card at the back of the book. Both the disk and the text will greatly benefit all undergraduates who would like to acquire a comprehensive understanding of environmental modelling techniques.

Originally published in 1990 and designed as a student text, The British Seas is a clear introduction to the oceanography and resources of the region. It is unique in providing a detailed review of the resources of the north-west European continental shelf together with a comprehensive description of the environment. Introducing the shelf region as if it were a new country, Jack Hardisty explores first its physical environment and then summarizes the distribution and exploitation of resources from the environment. Part 1 – on the oceanography - covers the shape of the shelf, its geological history and its wave and tidal regimes. Part 2 – on the resources – looks at trade and shipping, and the hydrocarbon, fishing and seabed mining industries. It goes on to discuss wave and tidal power, and to consider the problem of pollution in terms of resource utilization. The industrial technology and the environmental potential of each resource are examined, and the economic and legislative restrictions are analysed.
