Abstract : In the Port of Rotterdam and the adjacent estuarine area approximately 20 million cu m is dredged annually. The degree of contamination of the dredged material plays an important role in the choice of the method of work; it is therefore necessary to establish criteria for the selection of the method of work. The boundary conditions for the establishment of criteria are: a. Acceptability with regard to the environment. b. National law and international agreements. c. Technical and economic feasibility. d. Feasibility from the point of both management and enforcement. A classification of dredged material is being developed for the Rotterdam area. The present classification is based upon the mixing factor between contaminated fluvial silt and very lightly contaminated marine silt.
