Abstract A simulation model based upon in situ current velocity data and records of disposal events was developed to predict the chemical exposure field resulting from dredged material disposal plumes in Central Long Island Sound (CLIS) during the spring of 1983. In the model, plumes are assumed to form as subthermocline suspended particulate clouds which are uniform vertically and Gaussian horizontally. Horizontal cloud dimensions are allowed to grow with a constant diffusion velocity as the plume is transported by tidal currents. The model permits estimation of increases or elevations in suspended solids concentration above background levels at individual sites resulting from multiple disposal operations. Model predictions of time-averaged elevations compare favorably with those estimated from tissue residues of Mytilus edulis deployed in CLIS as part of a joint Environmental Protection Agency (EPA)/Army Corps of Engineers program to investigate dredged material disposal options.
