This book discusses coastal defense measures, which have not improved in the past few decades, and better alternatives. It emphasizes on the existence of stable bays in coastal geomorphology and their use in coastal stabilization. The conventional measures for saving beaches, such as seawalls, groins, offshore breakwaters, and renourishment, are discussed in detail, followed by an alternative known as headland control. Many types of coast, and the respective defense measures, are discussed, especially for eroding beaches downcoast of harbors with long breakwaters. The formation of offshore bars during storms is examined and the design of stable recreational beaches is demonstrated. Practical design problems are discussed in all cases. Many issues requiring attention in coastal engineering are also outlined.

Contaminated land and the methods and legal controls governing its reclamation for subsequent development and use are of great current interest and concern. This volume in the Issues in Environmental Science and Technology series contains seven articles which treat the many aspects of this subject, ranging from risk assessment and risk management, through specific remediation methods and the evolution of government policy and controls, to analysis of the legal and technical features of specific environmental insurance policies. The chemistry of the non-ferrous heavy metals lead, zinc and cadmium is examined in relation to reclamation of superfund sites in the USA alongside a consideration of the role of the Welsh Development Agency in developing strategies for the recovery of derelict and contaminated land. An authoritative treatment of each of the topics is ensured by the particular expertise and distinction of the authors, and as such Contaminated Land and Its Reclamation will make an important contribution to the public debate on these issues. It will be essential reading for all those groups of people directly or indirectly involved, from consultants and their technical advisors, through developers, contractors and landowners, to local authorities and government agencies with responsibility for policy and its implementation in this area.

This engineering manual, ""Coastal Groins and Nearshore Breakwaters"", from the U.S. Army Corps of Engineers provides guidance for the design and placement of beach stabilization structures, specifically groins, nearshore breakwaters and submerged sills. Since the design of beach stabilization structures requires analyses of the wave, current, and longshore transport environments and the coastal processes at a project site, this manual can only provide guidance and design concepts in the area of beach stabilization. However, in addition to the general guidelines, the manual does present a compilation of the advantages and disadvantages of the various types of beach stabilization systems.

Laboratory physical models are a valuable tool for coastal engineers. Physical models help us to understand the complex hydrodynamic processes occurring in the nearshore zone and they provide reliable and economic engineering design solutions.This book is about the art and science of physical modeling as applied in coastal engineering. The aim of the book is to consolidate and synthesize into a single text much of the knowledge about physical modeling that has been developed worldwide.This book was written to serve as a graduate-level text for a course in physical modeling or as a reference text for engineers and researchers engaged in physical modeling and laboratory experimentation. The first three chapters serve as an introduction to similitude and physical models, covering topics such as advantages and disadvantages of physical models, systems of units, dimensional analysis, types of similitude and various hydraulic similitude criteria applicable to coastal engineering models.Practical application of similitude principles to coastal engineering studies is covered in Chapter 4 (Hydrodynamic Models), Chapter 5 (Coastal Structure Models) and Chapter 6 (Sediment Transport Models). These chapters develop the appropriate similitude criteria, discuss inherent laboratory and scale effects and overview the technical literature pertaining to these types of models. The final two chapters focus on the related subjects of laboratory wave generation (Chapter 7) and measurement and analysis techniques (Chapter 8).

Fluvial, Environmental and Coastal Developments in Hydraulic Engineering contains the Proceedings of the International Workshop on State-of-the-Art Hydraulic Engineering (16-19 February 2004, Bari, Italy). The book is divided into four sections: -Air-water flows / Transitional flows; -Stepped chute / Transitional flows; -Environmental and coastal hydraulics with dispersion in estuaries and jets, and -Transitional flows. In this volume the energy loss of skimming flows is investigated systematically under a wide range of discharges, channel slopes, step heights, and dam heights. It is well known that in recent years environmental problems have an increasing pivotal role. The section on environmental and coastal hydraulics presents results on jet-wave interaction, which is still rare in literature. It also includes an attempt to reproduce the principal ocean circulation patterns by means of a numerical model, and to validate this with field measurements, using a Vessel Mounted Acoustic Doppler Profiler (VM-ADP). Other topics covered in this section are (a) tidal bores, which have a significant impact on estuarine systems, and (b) new fishway design and the effect of fishways on the migration of aquatic animals, including a design method for arranging the proposed fishway in the slit-type concrete Sabo dam. Various types of flow conditions are formed in accordance with inflow Froude number, boundary-layer development at inflow section, aspect ratio, relative downstream depth, channel geometry, Reynolds number, and air concentration at inflow section. As systematical clarification of the transitional flows is most significant for effective hydraulic design of hydraulic structures, varioustypes of transitional flows are analyzed, and presented. The volume is of special interest to scientists and students of hydraulics and fluid mechanics, to engineers, and to specialists in the field of environmental protection.

The necessity for a multi-disciplinary approach to reclaiming land is reflected in the contents of this text which considers all stages of land reclamation projects from the initial policy decisions to the management of completed schemes.

Proceedings of the 10th Regional Conference for Africa on Soil Mechanics and Foundation Engineering and the 3rd International Conference on Tropical and Residual Soils, held in Maseru, Lesotho, September 1991, are contained in two volumes. The papers address geotechnical problems peculiar to Africa and engineering solutions for local problems, as well as data on the properties of African soils.
