The Seacanal to Ghent. the water as well as the sediments, are heavily polluted due to the input of contamination coming from upstream and from wastewater of the industries along its banks. The application of Dutch and Flemish classification criteria defines the sediment as highly polluted. which removal and disposal requires special care. This article starts with considerations about the quantitative aspects of the sediments. Next, the quality is assessed. which is not at all easy regarding the continuous variation of the input and the output. Nevertheless a double approach is described: a pre and a post dredging approach. Starting from general ideas about remedial action for sediments, a script for the remediation of the Seacanal is proposed. The article ends with a brief description of the pratical consequences of the proposed script.
