SedNet was funded by EC DG-Research under the 5th RTD Framework Programme as a Thematic Network aimed at setting up a European network in the field of ‘assessment of fate and impact of contaminants in sediment and dredged material and at sustainable solutions for their management and treatment’. Between 2002 and 2004 more then 130 members subscribed to the network. In that same period scientific, policy and management aspects of contaminated sediments and dredged material were addressed in 17 workshops and 3 conferences. Europe’s leading scientists and major sediment managers contributed to these activities. The results are summarised in the SedNet booklet. The comprehensive results are published in 2006 by Elsevier as a series of four books.
