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.

This addendum to the Lower Passaic River Restoration
Project Modeling Work Plan gives an overview of how the
existing NY/NJ Harbor-wide model will be refined to
focus on Newark Bay.
