Abstract : This paper outlines active research at the Waterways Experiment Station on equipment and techniques for dredging contaminated sediments. The question is being addressed in three ways: the assembly and evaluation of available domestic and foreign information concerning sediment resuspension and contaminant release; the development of appropriate laboratory tests to predict contaminant release from resuspended sediments; and the use of field studies to monitor performance and compare dredges operating under various conditions. Plans are discussed for evaluating existing dredging equipment to determine best techniques for dredging sediments that are highly contaminated with toxic substances. Initial field studies have already been completed on evaluating sediment resuspension at the point of dredging for cutterhead, dustpan, and clamshell dredges. The results of these preliminary studies are discussed.
