The New York Bight had been receiving waste disposals, dredged spoils and acid dumps for the past 30-40 years causing accumulation of trace metals such as Cu(II) in water and sediment. A three-dimensional multi-layered time variable model has been developed to assess the temporal and spatial distribution of dissolved and particulate Cu(II) in the water and sediment layers. A chemical sub-model of this three-dimensional mass transport model computes the equilibrium chemical speciation of the metal in water and sediment layers. Sensitivity of the model was analyzed to determine the effects of different parameters such as, settling velocity of suspended solids, loading and dispersion coefficients, on the transport of dissolved and particulate Cu(II).
