Abstract: A two-dimensional mass transport model has been developed to integrate a hydrodynamic model and a water quality model for the Patuxent Estuary, Maryland. In this study, a two-dimensional, laterally averaged hydrodynamic model of the Patuxent Estuary based on the Wang-Kravitz modeling framework was used. The hydrodynamic results were averaged every 15 and 30 hydrodynamic time steps for the mass transport computations using the same spatial resolution. A QUICKEST solution scheme was employed to reduce numerical dispersion in the mass transport calculations. Comparisons of salinity results from the mass transport and the hydrodynamic models were made to insure a proper linkage of the two models.
