Abstract
A three-dimensional model of heavy metal transport was applied to simulate the copper content of the Oujiang Estuary. The modeled processes included not only the convection and diffusion of heavy metals in the water column, but also sediment-associated processes such as erosion and deposition of sediments, adsorption and desorption, and pore water diffusion and advection. The model was calibrated using measured data for water surface elevation, flow velocity, suspended sediment concentration, the proportion of copper sorbed in sediment, and the dissolved copper concentration. Meanwhile, the temporal and spatial variability of the suspended sediment, together with dissolved, particulate and total copper were analyzed.
