Methodology for Design of Fine-Grained Dredged Material Containment Areas for Solids Retention
A literature review revealed gaps in research concerning the use of existing procedures for designing containment areas for fine-grained dredged material to meet standards for effluent suspended solids levels. The literature review did provide the basis for developing laboratory and field investigations and for evaluating results. Four active dredging projects were used as sites to obtain samples of channel sediments and dredged material for laboratory tests, determine suspended solids levels of dredge discharges and containment area effluents, and to develop profiles of suspended solids versus depth for the containment areas. Dye tracer studies were used to investigate the short-circuiting and mixing properties of containment areas. It was found that grab samples taken from channel bottom sediments are adequate for performing sediment characterization and settling tests. Sediment organic contents were generally less than 10 percent for all the sites except one. In general the organics were considered to be too low to be a significant factor in evaluating the settling properties of the dredged material.
