This publication is a summary of good practice on the use of rock in engineering works for rivers, coasts and seas. It has incorporated all the significant advances in knowledge that have occured over the past 10-15 years.
The maintenance and upgrading of our built environment, including large sections of coastal defences, relies heavily on natural construction materials. The text aims to highlight a range of pressing research issues in natural construction materials of direct relevance to an industry facing growing pressures for environmental sustainability and standardization of product quality within Europe. Tests and specifications given in the forthcoming Eurostandards for aggregates and armourstones are considered and correlated with older more widely used tests, including those which could impact upon current road safety. This text should be useful to: aggregate and amourstone suppliers and users; civil and engineering geologists; quarry companies; and Local and County Authority engineers and coastal engineers.
These conference proceedings present authoritative papers on new experience and research, particularly that which has led to advances in design procedures. It covers design, construction and performance experience of coastal structures and breakwaters particularly including new developments.
Coastal Structures are undergoing renewal and innovation to better serve the needs of our society - from environmental co-existence and habitat enhancement to risk management. The CSt07 conference is the fifth in a series that highlight significant progress in the innovation, design and construction of coastal structures. Proceedings of these CSt conferences have yielded milestone works, frequently cited references in the field.This two-volume proceedings contains the final revised version of 178 papers that have been reviewed, selected and discussed at the CSt07 conference. The volume brings to readers a comprehensive range of contributions, covering all aspects of research, design, construction, and maintenance of coastal structures including new up-to-date interesting topics, such as tsunamis and storm surge defences, climate change, piled coastal structures as well as ecological issues, a new addition to the traditional program.
The present edition, with new title Coastal Engineering, is the enlarged and updated volume of the book origin-ally published under the title Coastal Hydrodynamics in 2012. The book provides an overview of world population and ocean resources, natural threats and man-made hazards, and their impact on coastal environment. It discusses the fundamentals of wind, waves, tides and fluid flow and describes commonly adopted wave theories in coastal engineering. The text explains the methods for estimating wave forces on coastal structures, procedures for the analysis of wave data, and sediment transport. Apart from the estimation of beach profile evolution and shoreline change, the book discusses key aspects related to the design of different coastal structures. NEW TO THE SECOND EDITION • Includes two new chapters on Beach Profile and Shoreline Evolution and Design of Breakwaters and Coastal Protective Structures • Colour photographs are appended at the end of the book KEY FEATURES • Worked-out examples will benefit the reader to understand and solve variety of coastal engineering problems. • Exercises given at the end of each chapter would benefit the reader to get exposed to a variety of practical problems related to coastal engineering. TARGET AUDIENCE • B.Tech./M.Tech. (Ocean Engineering/ Marine Engineering)
Describing the nature of the marine environment and the effects of man-made structures on the behaviour of the sea, this books deals with hydraulic design, the material properties of concrete and the design and specification of structures for coastal environments.
Over £500 million is spent on coastal and maritime construction in the UK every year. This work is particularly hazardous due to the hostile environment and uncertainty caused by the combination of storms, waves, currents and tides. At present, there is little health and safety related guidance available to assist coastal/maritime clients, designers, contractors and other stakeholders to ensure this work is undertaken in a safe manner. The CDM Regulations, amongst others regulations, require these parties to consider and assess construction risks.
This volume contains six papers discussing coastal processes, and physical and numerical modeling.In the first paper, Svendsen and Putrevu give an extensive review on the state of understanding of surf-zone hydrodynamics, including subjects such as wave breaking, wave-induced currents, and instability of nearshore currents and infragravity waves. They point out that the most urgent need is to develop an adequate theory for wave breaking and broken waves in the surf zone.One of the methods for studying the complex coastal processes is to perform laboratory experiments. However, physical models are always plagued by scale and laboratory effects, because the coastal process involves many different length and time scales. In the second paper, Kamphuis presents a detailed discussion on the sources and implications of the scale and laboratory effects on physical modeling.The third and the fourth papers are two parts of the discussion on the mathematical modeling of the meso-tidal barrier island coasts. To understand the dynamics of coastal inlet systems, one can either rely on empirical knowledge and construct various forms of empirical and semi-empirical models (Part I), or develop a set of mathematical models based on the physical processes (Part II). Although these models do not provide the details of the dynamics, they give valuable knowledge of the equilibrium-state relationships. de Vriend and Ribberink give a detailed review on two models, Initial Sedimentation/Erosion models and Medium-Term Morphodynamic models. They have also presented many examples of applications.In the fifth paper, Houston gives a brief review on different methods to mitigate beach loss caused by storms or persistent long-term erosion. He then describes, in detail, the method of beach nourishment, which is also called a beach fill. This paper discusses the information that must be collected to design a beach fill and that should be monitored after the completion of the project.The last paper of this volume shifts our attention to the design of offshore structures, such as gravity structures, floating barges and tankers. Chakrabarti discusses the effects of the uniform and shear currents on fixed and floating structures.
