Abstract: A methodology is presented for interfacing a three-dimensional, time-varying, intratidal hydrodynamic model with an intertidal water quality model of Chesapeake Bay. First-order Lagrangian residual currents are used to advect the water quality constituents. Comparisons of salinity time series computed with the two models are in good agreement, demonstrating successful implementation of the transport interface.
