Numerical simulation of Heavy Metal (Pb) Distribution in Luoyuan Bay based on Tidal current

Compared with the data measured by other ones, the concentration of heavy metal (Pb), which is investigated by us in July 2011, has increased significantly in Luoyuan Bay, especially near Baishui Zone. The main reason is the discharged waste water from some recently founded large-scale steel plants around Luoyuan Bay. A numerical tidal current model in Luoyuan Bay is established based on FVCOM, with which a heavy metal transport model is developed to simulate the distribution of Pb discharged from steel plants.Reasonable agreement between the model results and field data has been obtained, indicating that the numerical model can be used as computational tool for environment management and the prediction of heavy metals in Luoyuan Bay.
