This work provides comprehensive guidance on maintaining old waterfront walls, especially gravity walls constructed with stone masonry, brick blocks or mass concrete. It should be of use to engineers and owners responsible for such structure. Many existing waterfront structures (harbour and dock walls, breakwaters, seawalls, flood defences, skin walls, bridge piers and abutments) are crucial parts of industrial or environmental facilities. Many date back to the 19th century and earlier, and information on their design and construction is often incomplete. They are often massive structures, and the problems of working over or under water and on the buried back of the wall mean that they are difficult and expensive to investigate and maintain, yet they represent substantial capital assets and appropriate management and maintenance are essential. This work draws together a wealth of information and experience on the types of wall that were constructed up to the earlier part of this century. It includes numerous drawings and illustrations of these walls and reviews their performance. It goes on to identify and describe the most suitable techniques available for their inspection, struct

Expanding a port, deepening a navigation channel or creating new land for development, introduces changes to our physical, social, economic and political environment. Changes may result from events during the construction process, or relate to the nature of the completed structure. Changes can be positive or negative, short-term or long-term, and may affect the immediate vicinity of the project or a larger geographical area. Predicting and assessing all possible effects of a planned dredging activity in a scientifically-sound and reliable manner is essential, so that appropriate control measures can be taken to avoid or mitigate unwelcome impacts. This book provides guidance for a complete holistic environmental evaluation procedure and for the design and implementation of environmental control measures. The book is of particular interest to engineers, government agencies and port authorities, as well as civil engineering consultants and contractors involved in planning and designing dredging, maritime infrastructure and fluvial projects.

This book provides comprehensive guidance on maintaining old waterfront structures, particularly gravity walls constructed with stone masonry, brick, blocks or mass concrete. It will be valuable for all engineers responsible for such structures.

For this second edition of the highly successful 'Dredging: A Handbook for Engineers', Nick Bray and his co-authors have fully updated and expanded the book which covers all aspects of modern dredging including operating methods, outputs, costs, contracts and the impact on the environment. Planning and implementing dredging projects, including pre-contract works, is also well covered. The book is generously illustrated with line drawings, photographs and tables, and a useful bibliography appears at the end of each chapter. This definitive handbook will prove invaluable to engineers and managers alike, both as an initial introduction to this specialised topic and as a reference for years to come.
