Abstract : A technique for predicting the quality of effluent from confined disposal areas during dredging operations has been developed as part of the Long-Term Effects of Dredging Operations (LEDO) Research Program. Such a technique is necessary for design and/or evaluation of disposal areas to ensure that applicable effluent standards can be met. Dredged material placed in a confined disposal area undergoes sedimentation, resulting in a thickened deposit of settled material overlain by the clarified water. The supernatant waters are normally discharged from the site as effluent during active dredging operations. Removal of the normally oxygen-free sediments from the channel bottom and placement of the material in a confined disposal site where oxygen is present will also influence the mobility of contaminants.
