SEDIMENTATION ENGINEERING TECHNIQUES FOR ENVIRONMENTALLY-FRIENDLY DREDGING

This paper addresses the issue of mud maintenance dredging in harbours. Port authorities face pressure to decrease the quantities or cost of dredging and at the same time the challenge to dredge with the least environmental impact. Two contrasted techniques, which have led to parallel cost reduction and environmental benefit, are presented as examples. Sedimentation engineering will increasingly offer prospects for progress in these areas in the twenty-first Century.
