Understanding dredging


CEDA-IADC handbook: Sustainable dredging (in preparation)

Since the CEDA-IADC book “Environmental Aspects of Dredging” (ed. N. Bray) was published in 2008, there have been considerable advances in knowledge about the natural environment and its processes and dynamics. The focus of thinking in relation to dredging and the environment has shifted from dredging and managing contaminated sediments to turbidity by clean sediment, sound, light, greenhouse gases, combined effects on habitat systems etc. The attitude towards the environment has changed from a reactive to a more proactive attitude where environmental considerations are included in projects at the earliest possible stage, where nature-based approaches, value engineering, win-win solutions (i.e. benefits / value for all parties) dominate the thinking. Also the tools available to assess potential environmental consequences of dredging projects – positive or negative – as well as dredging equipment and technology have developed considerably.

The Boards of CEDA and IADC therefore felt it was time to summarise the new knowledge and experience make it available to a broad audience in a new book.

The aim is to produce a handbook, an invaluable reference material to engineers and scientists world-wide, involved in dredging projects either as developer, regulator, consultant or contractor.

The target date for publication is early 2016.The book’s outline and content is largely based on the outcome of a workshop where some 30 experts from a range of countries participated representing all facets of the dredging sector. They defined what specific content, type of data, recipes, guidance, tools and concrete examples the book should contain to be of value to them.

The process is guided by an Editorial Advisory Board comprising CEDA and IADC representatives who ensure an objective, comprehensive and consistent coverage of all relevant subjects.
