A three-dimensional polychlorinated biphenyls (PCBs) model is developed to explore the fate and transport processes of PCBs in the Baltimore Harbor (BH), a coastal embayment located in a highly urbanized watershed of the Chesapeake Bay. The PCB model is an organic carbon-based model coupled with an eutrophication model and is driven by a three-dimensional hydrodynamic model. The modeling framework...
The problem of eutrophication model calibration is formulated as a coupled, multi-objective optimization. An optimal algorithm is integrated into a vertically averaged, two-dimensional eutrophication model for the model calibration. The sensitivity coefficient matrix is used to estimate the Hessian matrix. The modified Gauss–Newton method is used to estimate the unknown parameters. The approach is...
