Modeling

The USEPA, along with its partner agencies on the Lower Passaic River Restoration Project, is refining an existing NY/NJ Harbor-wide model to focus on the Newark Bay Study Area and Lower Passaic River watershed. The existing Harbor-wide model was developed by the NY/NJ Harbor Estuary Program for use in its Contaminant Assessment and Reduction Project. The refined model will be used to predict how contaminants are moving within the Lower Passaic River and Newark Bay.

Final Hydrodynamic Modeling Report [January 2008]:   This report presents the 3-dimensional model created to describe the circulation of water throughout the Lower Passaic River and Newark Bay Study Areas. The hydrodynamics of the system are predominantly controlled by 3 mechanisms: freshwater flows, tides and winds. This model was developed with the goal of eventually being able to predict the movement and concentrations of contaminants of concern within the 2 study areas under different future scenarios such as dredging, capping, or monitored natural attenuation. This report includes a calibration and validation of the hydrodynamic model. These are procedures where the developed model is run and the results are compared to data observed in the field to determine whether any refinements need to be made to the model. In general, the model results were in agreement with the observed data.
